Yikong 4106 Pro Has a Party Trick!

Yikong 4106 Pro Has a Party Trick!

Inspiration, Not Imitation

Yikong 4106 Pro is a 1/10 RC crawler with an ability we have not yet seen in the RC crawling world. You may not have heard of Yikong before, but they’ve been quietly making some interesting models over 2023 and now 2024. This latest one will knock your socks off, once you consider the ramifications of what they’ve made. But first, some details.

This is a model that combines the best features of the offerings of the likes of Axial’s SCX10 III with 2-speed transmission and DIG (disengages drive to the rear, then locks the rear, for tight turning and improved rock crawling ability) and the Traxxas TRX4 with its remotely activated locking diffs.

The Killer Feature

But what makes the Yikong 4106 Pro special is something new that we haven’t seen in RC cars ever before: independent disc brakes! They’re only in the rear and they activate via a button that mixes their function with the vehicle’s steering. They work by clamping the inside wheel on a turn, when activated. So, when you turn left, for example, the rear-left wheel is braked, helping to really tighten the vehicle’s turning circle. Genius!

On the Floaty Side

The suspension is a bit on the floaty side, with considerable body roll. The vehicle has portal axles, which helps cancel out torque twist while also increasing undercarriage clearance on rough terrain. The shocks are “oil-filled” but the unit I received had “oily” but empty shocks. I’d suggest adding 30wt oil to create some needed damping.

Shocks can be mounted in a variety of positions, which is very welcome. They’re neutral, by default, and I like them there for trail and light crawling. Shock preload is adjustable by thumbscrews, and I found that winding on about 8mm in the rear really helped it with crawling. Now it isn’t so fast to lift a front wheel on steep ascents.

4106 Pro Servos

In the below photo, there are three servos closest to the camera. The first two are the diff lock servos, and then the one closer to the battery is the 2-speed servo. These are waterproofed servos with low power, I’m guessing maybe 2-3kg. Plastic gears, plastic spline, that kind of thing.

My front diff lock servo was broken, out of the box. I may replace it with another similarly cheap unit, or I may even just leave it be. I don’t mind the front being locked all the time. It’s the rear one that wants to be able to unlock, both for general driving and so that the ‘tank steer’ feature can work correctly.

The steering servo is a metal geared unit and has plenty of punch. I’m guessing 15kg or so, which is fine for this car.

Electronics

The ESC and receiver are an all-in-one unit from Flysky, which is OEM-only at time of writing. The Flysky FS-MG11-BS radio system incorporates a connected light kit that is designed to work with the radio system. It manages a lot of complexity in an elegant way. I like it. (It’s the same one you’ll find with the new FMS FCX10 1/10 model, and no doubt we’ll see it in other vehicles soon, too).

The car can take either a NiMH battery (6 or 7 cell), or 2S or 3S lipos. The ESC has a Deans (or T) connector. The power switch is located underneath, behind the skid, and is waterproofed.

The radio transmitter takes 4x AA batteries and you’ll need to supply all the batteries for this vehicle.

The motor is a large, 550-sized can with 32 turns. It’s well suited to the vehicle and I like it on both 2S and 3S.

Axles & Undercarriage

Axles are a pleasing scale design, with smooth lines and bolts in the right places. They engage well, seem like they’ll be durable, and the portals are tastefully implemented. No hulking, unnecessary chunks of plastic here. The front axles are steel universals, adding to their strength and something I always want to see in a crawler.

Thoughtful design is what you’ll find underneath the vehicle. Stainless steel links and inverse-rotation drive shafts are also like this. There’s a servo saver in the form of a passive steering damper on the steering link, too. It’s a solid undercarriage, overall. Nothing is hanging down to be grabbed by sticks or rocks and it just looks good.

Now, you may have read that it has a molded plastic chassis instead of the usual steel stamped C-channel rails. This is true. But, it works. The car is lighter for it, flex isn’t a huge issue and it keeps the cost down. I don’t see a down side in this model with that choice.

Mercedes & Hyrax: Clone Wars

The wheels are 2.2″ and look like the real thing, with the tiny Mercedes G-Wagon spokes around a solid wheel hub. The tire treads are not so scale, being a Proline Hyrax clone, but run on a 4.56″ tire carcass, which Proline does not make. Not entirely a clone, then – though the treads themselves clearly are Hyrax. The foams are a little on the firm side but they work well.

A Mysterious Interior

This G63 body has a complete interior, including dash, steering wheel, dash details and shifters, seats front and rear, and nicely finished. It’s in moulded polycarbonate, keeping the weight low.

However, there’s been a weird decision to apply a frosted, semi-opaque paint layer to the inside of the body on the windows, making it possible to only see the blurred outline of the seats, at best. Why go to the trouble and expense of including an interior, only to hide it? Perhaps subsequent manufacturing runs have removed the paint from the windows. I hope so.

Front Bumper Dilemma

The car comes with a solid plastic front bumper that can be installed. By default, it is not installed, instead allowing the stock polycarbonate body to show off its pretty, moulded front lower grille. If you want to install that front bumper, some of the body needs to be cut away to fit it. I was going to do this on mine but realised it would look worse. Cutting it is a one-way decision, so I’ve decided to keep mine as it is.

I should also add a note here about the sliders. They look like the aluminum of the real car -that is to say, they’re molded and painted on the polycarbonate body here. That means they look great, but it also means they’re weak. Just like the real thing, they’re really just for looks. You could beef it up with steel or plastic underneath, but it would be a custom job. As far as I know, there aren’t after-market rock sliders available for this model (yet).

Lighting Up the Trail

The body also enjoys a complete light system. It functions as part of the integrated Flysky receiver/ESC/light unit and provides full-function lighting. Low beam, high beam, flashing, indicators, braking, reverse, and fog lights are all part of the vehicle’s abilities. Looks great and you can switch between off, low, high, and flashing configurations.

4106 Pro Light Kit

Drive Modes

Also part of the Flysky system is a set of DIP switches on the radio transmitter. Switch 1 toggles driving mode from Fwd/Brk/Rev (trail driving) to Fwd/Rev (crawling). In the Trail mode, the taillights increase red luminosity when braking. In Crawl mode, there is no braking; you simply see the white Reverse lights when reversing, and the low-glow red taillights when otherwise stationary or driving.

Speaking of the transmitter, the wheel feels very premium. There’s a weight to it, though plastic, that has the feel of a much more expensive radio. The spring is light, the balance neutral, and it just feels great to use. The throttle trigger also has a pleasingly light action.

4106 Pro ESC

Radio Freedom

There are many options on this radio and happily, many are not used. There’s a thumb dial that has maybe 5mm of movement from neutral in each direction – that isn’t populated on the receiver, so it’d make a great winch controller or rear steer option.

On top, there’s a button and a dial that also aren’t used on the receiver (unless mixing interferes with this; I haven’t tested them yet), but you end up with quite a few options. You could put a sound system in the car and have the spare top button as a horn, for example.

Drag Brake on the Fly

Lastly, the radio also gives you a dial (Ch.11/Drag Brake) that allows the drag brake rate and intensity to be adjusted on the fly. The maximum setting feels like the equivalent of about 70% drag brake on a WP-1080 ESC (incidentally, see our programming guide here), in this vehicle. The minimum setting is basically zero drag brake. My video review shows the difference between these on the steep rock descent near the end. It’s a nifty feature.

Yikong 4106 Pro Driving Dynamics

The car drives quite nicely. This is a scale vehicle more than a performance machine. With it’s many driving accessories, it’s very fun to play around with. The two-speed transmission has a pleasingly wide ratio between first and second. The lockers engage nicely – well, I should say, the rear one does.

The front one does too, when I do it manually, but my front locker servo arrived faulty, so I can’t tell you from experience. I’ll swap mine out for a replacement servo (just a mini size, they’re pretty universal, so no worries there) and it’ll be fine. The so-called ‘tank turn’ feature of those rear disc brakes is just fabulous, and the lighting kit in the pretty body makes night driving possible and day driving more scale.

Back to the Big Thing

Now, onto those ramifications I mentioned in the intro: independent disc brakes. Yes, this model uses a single servo to modulate between left and right, for the sole purpose of tightening your steering radius when active. It works well. But as a proof of concept, now we know disc brakes work and that they can be rugged enough to be effective in an active, wet-n-dirty off-roader. On its own, that’s already impressive, right?

4106 Pro Disc Brake Servo

Now Think BIG

Okay, now think about faster cars. The Arrma Infraction has a disc brake on the rear outdrive from the transmission, for example. (Incidentally, buy an Infraction using this link for a discounted purchase; it’s my all-time favourite street car and so very worth it). Already a super fun, super powerful street machine, you now effectively have a hand brake feature on an 80mph-capable street basher. Nitros have also been using a disc brake on the drive shaft for years.

But to have disc brakes independently on each wheel? This means the traction control of full-size cars can be brought into road and track RC cars! Do you see the potential here? We already have the technology in the tiny ESC modules of current RC vehicles. Add a few extra servos and now you have something that can brake each wheel as traction is lost in a corner or under acceleration, and so on. What an exciting idea! I don’t know of any other manufacturer currently doing this, but I’m hopeful and excited to see more. Wow!

Final Thoughts

Frosted interior windows aside, the Yikong 4106 Pro is very well thought out. A manual would be appreciated, especially for hobby newcomers, as there’s a LOT going on with the radio. Thankfully, it’s well labelled.

I don’t support the blatant IP theft that Yikong have seemingly undertaken from Mercedes with the pretty G Wagon body, nor from the Hyrax tires. But, on the whole, they’ve created something special.

I’m loving the progress we’re seeing from these smaller brands and I’m so pleased the Yikong 4106Pro is not just another clone of an existing vehicle. It’s fun to drive, capable for what it is (think ‘Class 1 comp crawler’ and you’ll be pleasantly surprised) and it looks great. Recommended.

Losi Super Baja Rey 2.0

Losi Super Baja Rey 2.0

It’s Huge

The Losi SBR 2.0 is one of the larger RC cars available today (currently on sale here). But it’s also quite different to most of the other 1/7, 1/6 and 1/5 scale fare you can choose. It might be the most unique offering in this scale, now I think about it. Consider: if you want to bash hard, you buy an X-Maxx, Outcast 8S or Kraton 8S. If you want to crawl or trail drive, the SCX6 has you covered. Large scale race track nearby? Get yourself a Losi 5IVE-T 2.0 or a DBXL and have at it. HPI’s Baja 5B has you sorted for big buggy action.

But what if you want scale desert truck driving? Humungous suspension travel, the kind of cornering that only a live rear axle can deliver? Something to match the Traxxas UDR favored by so many? But… bigger and more aggressive? Losi has you covered with the Super Baja Rey 2.0. Let me show you what makes this enormous monster so special.

Losi SBR 2.0

This is a 1/6 scale desert truck. I didn’t have the original one, so I can’t give you a side-by-side comparison, but Losi says this one is built on the Super Rock Rey chassis, but with an extra inch of wheelbase length. They’ve combined it with the front of the Super Baja Rey and there you go, SBR 2.0.

It’s a four-wheel drive vehicle that is engineered to be tough – but of course, with the live rear axle, it will take the right driving approach to keep the wheels on the ground. This style of vehicle is made to soak up big bumps at high speeds. While they can slide and corner reasonably well, this will never be a basher to replace the likes of the Arrma Senton 6S or similar, with its independent front and rear suspension. I guess you could say that RC desert trucks – the SBR here, the BR2.0, Traxxas UDR and so on – are all about the scale drive.

Body Issues

I’ll start with something that was a bit of a let-down. It’s only minor, but this isn’t a cheap model and so you expect the thing to be pristine out of the box. For this design, Losi elected to use something like vinyl wrap for the livery. Mine was a little worse for wear, with cracks in the decals around folds and edges. Some sheets were even misaligned. Screws were oxidized and there’s dust under the light bar lenses.

To be fair to Losi, this is surely a challenging model to assemble. Even in a production-line style setup, I expect it would take considerable effort to get something like this together without mistakes. But to find so many minor issues with my unit does make me wonder about quality control. Is it only the body I should be concerned about here, or will there be missing grease in diffs or a critical screw not secured completely?

Still Gorgeous Tho

The issues I had with this thing are only skin deep, as far as I can tell. At time of writing, I haven’t run the car yet, so if there are underlying mechanical oversights, I’ll edit this section later to let you know. But if you’re not looking closely, those misaligned panels and livery sheet cracks are not obvious. It’s all forgivable when you step back and take the thing in. This is a machine of beauty.

Radio System

Cars rarely came with radio systems in decades past. However, relative to RTR (Ready To Run) sales, kit builds are a lot less popular than they used to be. Many hobbyists may still prefer a kit (including me), but it isn’t what sells. Instead, manufacturers are typically now releasing models with everything assembled and included. The included radios with RTR systems have been hit and miss, maybe more on the ‘miss’ side for some time.

Horizon Hobbies has several big brands under its umbrella at this point. This includes the Losi vehicle here, but notably, also Spektrum. This is why you’ll get a Spektrum radio and power system with most Horizon-brand RTR models these days (Arrma, Losi, Axial, and so on). While the common and more basic Spektrum SLT3 system is fine, the better one is the Spektrum DX3 with 6100AT AVC receiver – and that’s what comes with the Losi Super Baja Rey 2.0.

I like this system in particular because of two dials that make it so much easier to use than so many others. The first is an adjustable braking dial – turn it up for more aggressive braking. The second is a stability control dial, or steering gyro – turn that up to have the car counter-steer more responsively to keep the nose pointed forward. In a car like this, I’d suggest the former is quite important and the latter is probably best left turned mostly down. Experiment and see; it’s so easy to adjust on this radio. I’m a fan! (The marks and dust are because Metro Hobbies sent me a floor model without telling me. Disappointing, but not a big deal).

Losi SBR 2.0 Spektrum DX3 Radio

The Main Thing

This is what we’re here for: that epic, desert truck suspension and live rear axle. Check these pictures out! Look at how much range there is, especially over the rear axle. It’s plush, heavy-duty and epic. Of course, the rear suspension is mounted on trailing arms, and everything about the arms at both ends is heavy duty and well designed. There are hefty sway bars at each end and it looks great. Even just typing this, I’m wondering how I’ve managed to not drive this car yet. I’m busy, but too busy to drive this car? I’m selling myself on this thing just writing this.

The front end has plenty of travel as well and the body has a pleasing amount of roll. There’s bolstering around the chassis mounts and both ends are adjustable with alu thumb screws. Looks great, too.

Drive Line

Steel universals are found throughout the vehicle’s drive line. The rear shaft is a fibre-infused telescoping unit that attaches to the steel unis at each end. Given the crazy power this car can make (and we should talk about that in a moment, see below), you’d reasonably question if plastic will be up to the job on the rear end, in particular.

Well, there are steel drive shafts available on the after-market for this car, but having discussed this car with other owners, the consensus seems to be that it’s tough enough for the job. Certainly, there’s not a lot of flex in the parts, but rigidity is probably the more important element here. The glass element should be sufficient. We’ll see!

Losi SBR 2.0 Rear Shaft and Links

Wheels and Tires

BF Goodrich Mud Terrain T/A KM3 tires are clamped securely in Method Racing beadlock wheels on 17mm hex adapters. Side walls are firm but have some flexibility and the foams are also medium-hard. Of course, there are the two full size, functional spares on the rear of the vehicle, which is part of the magic of this interesting car.

Power System

Bigger numbers don’t necessarily mean bigger speed. With RC power systems, getting the voltage, motor kv (revolutions per volt), and gearing correct can be a balancing act. Typically, larger scale vehicles will run lower kv motors, favouring higher volts to achieve the torque and power required to move a heavy vehicle rapidly.

The SBR 2.0 runs a Spektrum Firma 160A 8S-capable ESC, powering a hefty (no, really) 5687 750kv motor. This is both a huge diameter and lengthy can – this motor is 56mm across and 87mm long.Batteries are loaded from the bottom of the vehicle, also helping to keep the weight low. It has a claimed top speed of around 50mph. Doesn’t that sound kind of uncomfortable! Fun, though!

Losi Super Baja Rey 2.0

How does it drive? Well, I can’t give you that quite yet. I’m looking forward to it, but I’ve been waiting to drive with a Traxxas UDR so we can compare them a bit. I might try to throw in an Arrma Mojave 6S as well, and then we can see which might be the best to get for your purposes. I’ll put that video here, when I make it. I can’t wait!

Which RGT Trail Rig  is Best for YOU?

Which RGT Trail Rig is Best for YOU?

RGT Pro Runner

The RGT Pro Runner EX86130 is just the latest in a growing line of interesting and capable RC crawlers and trail rigs. And hasn’t RGT been on a roll this past year or two!

On our YouTube channel, RGT has featured every now and then when there’s an interesting release to examine. But it was almost as if the company was just warming up for 2023’s big releases that we’re now so lucky to be able to choose from!

RGT’s Other Options

Fans of the channel will recall the well-received RGT Pioneer EX86110, which was arguably a forerunner of the current upper echelon of EX861XX models. (Find our RGT Pioneer video series here). With some careful upgrades on a budget, the Pioneer is an exceptional all-rounder. The EX86010-CJ is also a budget stand-out, while we’re at it. (Video here).

Also, I should note up-front that there’s a gap in our coverage of this family of models: the RGT Tracer EX86180Pro. This is a 4WS-enabled SCX10 Pro type vehicle, and one I think we should try to get hold of in the new year. For now, just be aware that it’s an option for those with a rock-crawling focus rather than trail aspirations.

3 RGT Models - Top

The Three Contenders

If you love a mix of trail driving and scale rock crawling, things are now very interesting. As of the start of 2024, there are three fantastic models that the discerning RC trail driver and scale crawler driver will want to know about:

Let’s take a look at them!

RGT Rescuer EX86190

There’s a complete article about this model on RC-TNT.com here – have a read when you’re done with this one. The scale crawling and trail driving community had their interest drawn to RGT’s mid-2022 release of the RGT Rescuer (EX86190). And it wasn’t just the attractive 70-series Toyota Landcruiser body – though unlicensed – that made this RC crawler something special. Sporting essentially the same feature set as the full-version Traxxas TRX4, the Rescuer’s scale looks, 2-speed and remote locking diffs made for a very attractive option.

What really stood out to me in my testing of this model was its fun factor. The vehicle rides on 4.75” tires and the live portal axles work under alu-shock, oil-filled, coil-over suspension on all corners. With a moderately high center of gravity, this leads to a scale model that moves pleasingly, with body roll that mimics the real thing. There are many RGT mods available. You can improve the vehicle’s CG (Center of Gravity), for better crawling with some brass parts. Or, you might better light the way  with bull bar and roof rack light bars complement the existing light kit. Maybe you want to improve the scale model experience with a complete, polycarbonate interior, with driver. You can do all of this!

RGT Challenger EX86170

On the heels of the Rescuer, RGT next released the Challenger. This was more of a retro style pickup truck and in my opinion, its features put it roughly in between the Rescuer and the Pro Runner. Like the Rescuer, the RGT Challenger sports a pair of portal axles, with a 2-speed transmission that incorporates a DIG (rear axle locking), opposite-spinning drive shafts to minimise torque twist, and a built-in 6.6% overdrive to the front axle.

This attractive machine also sports a rear-facing servo winch, sway bar system on the rear end and a functional light kit! Priced only marginally less than the Rescuer, this is another compelling model. I found there were a few ways to modify this model to make it more convenient to use, but there’s very little this vehicle needs addressing, out of the box. A solid choice.

RGT Pro Runner EX86130

I found the Rescuer to be fun and the Challenger to be quite complete. And so the RGT Pro Runner EX86130 took me quite by surprise, not least because it costs about 20% less than the other two! The Pro Runner is another unlicensed body that looks very close to the Traxxas TRX4 2021 Bronco, even down to the smaller details such as the ABS plastic folding side mirrors and similar front grille. (Quick note: the top photo in this article shows the Pro Runner with different tires. The plastic, silver beadlocks are standard, with the 4.19″ tires. See the rock test video for how good they are).

However, the Pro Runner is special for two reasons, I think. First, the price – in Australia at least, I can buy two Pro Runners for the price of one TRX4 2021 Bronco. That’s already quite significant. Secondly, the feature set – it is vast! Check this out: 2-speed transmission with DIG, 6.6% overdrive and opposing rotation drive-shafts, just like the Challenger; full-function light kit, including brakes and reverse options; straight axles rather than portals for added scale; front-facing servo winch; servo-on-axle hidden in such a way that you’ll miss it if you’re not looking for it; steel universal front axles for greater turning angle and strength than the CVD-equipped Rescuer and Challenger’s portal axles. What a list!

How Do You Choose?

That really is the question, isn’t it? I am in the process of making a video about this, and I suppose writing this article is helpful in distilling my thoughts on this difficult choice. There are some little quality-of-life things, like how the body attaches to each (see the below picture), but the unique blend of features, capability, appearance and handling all add up to something different in each case.

So, I do have some thoughts that you may find useful. I’ll try to use this to guide you on why you may (or may not) decide to select each one. Read on!

RGT Body Attachment

Fun

This is the first, and to my mind, most compelling reason to consider any of these vehicles. For trail driving with some crawling, one vehicle really stands out to me: the Rescuer. Why? Consider the remote locking diffs in the portal axles, for a start. The Challenger has portals and the Pro Runner straight axles, but being able to remotely run them unlocked means more scale fun on the trails. When traction gets harder to find, lock one or both ends!

The second part of the fun formula is scale handling to match the gorgeous looks. With the suspension setup on the big, bouncy tires, the Rescuer rolls and moves like few others. I’ve driven this through deep water, mud, rocky ground, and long dirt paths. It just keeps on trucking and it looks great doing it. Vote 1 for Rescuer if you’re shopping for fun!

Modding

There are two kinds of RC crawler owners: those who mod their rigs, and those who just haven’t done it yet. The Challenger is a very complete vehicle out of the box, yes. However, there are a few things you can do to improve its design for easier daily use. I actually cover some of these in my modding video, linked at the end of the article.

But, aside from fixing wiring and putting a body-stand in place, there’s one mod in particular that this vehicle is just begging for: converting that rearward-facing winch to power a rear towing assembly! They’ve actually done most of the work for you already. A boom assembly could be made from aluminum, braised from mild steel, or even achieved with some 3D-printed beams (the last of which I think might be the way I go with it). You already have the winch, so re-route the cable and add a tackle block under the end of the boom and you’ll be done! The Challenger gets my choice as most promising for mods.

Budget All-Rounder

Fun is subjective and not everyone wants to convert a trail rig into a tow-capable machine, I get that. Where I think we’ll all find common ground is on the subject of sheer value for money. On that front, the Pro Runner absolutely and completely delivers.

I took this car with me last weekend to a meet-up with a bunch of folks and we went on a 4-hour mudding adventure in the Aussie bush. Water crossings, treacherous rocky ascents, muddy gullies, greasy clay climbs – this day had it all (video here). I ran the Pro Runner on 3S, which the included WP-1060 allows (and all three vehicles have the same ESC and steering servo, by the way), and this vehicle was reliable and fun. It wasn’t the most capable, with those small 4.19” tires and straight axles, but oh, boy, was it satisfying to wheel. I can’t recommend the Pro Runner enough, if you’re on a budget and want a single all-rounder. Get this, you won’t regret it.

The Bottom Line

So where does that leave us with the choice? Chances are, you already have a pretty good idea of which you prefer after reading the above sections. And if you’re noticing that, wait a minute, none of these three has the remote locking diffs AND a DIG AND portal axles AND a winch, well, yes, you’re right. But not even Axial or Traxxas will give you all that, out of the box. The TRX4 2021 Bronco comes close, as it currently even includes a winch, at time of writing – but no DIG. The Axial SCX10 III gives you DIG and portals, but the diffs are locked full-time. And they are both considerably more expensive than any of the RGT offerings, at least, in Australia.

If you can’t decide and all three grab you, I do have one final suggestion: buy the one that moves you. Pretend you’re going with one of them and see how you feel about not getting either of the others. Repeat for all three vehicles; you may just find you’re most wistful about ‘missing out’ on one of them in particular, and that would be the one to get!

Bezgar HP161S – A Confession

Bezgar HP161S – A Confession

Trouble In Paradise

The Bezgar HP161S is a 1/16 RTR Monster Truck. It’s a tiny little package of durable and speedy fun! Sounds like a slam-dunk video and article combo, right?

You’d think so! And yet, things have not gone to plan. And on that note, here’s a letter I’m overdue on sending to Bezgar…

Bezgar HP161S Water Jump

We Need To Talk

Dear Bezgar,

I have a confession. You sent me the Bezgar HP161S 1/16 Brushless RTR Monster Truck earlier in 2023. I was excited about it, as I’d really enjoyed the similar Rlaarlo XDKJ-005 and figured this might be something like that experience – which was very good, all told.

It arrived! I unboxed it, filmed it, then put it back in its box. All the data was on my laptop waiting for me to make the video. All I had to do was edit it and get it onto YouTube.

But I just… didn’t.

Instead, the mighty little monster truck just sat there in its box, waiting.

And waiting.

Weeks passed.

Bezgar HP161S Weight

A Problem

You see, after I first played with it, I just didn’t ‘get’ it. I didn’t enjoy running it on my rocky driveway, not at first. The little truck was bouncy on the oversized gravel and it inevitably flipped over a bunch. I couldn’t speed-run it on my street, as it felt uncontrollable at higher speeds.

I really wanted to like it, but I simply didn’t enjoy those first few sessions with it.

And so, in my typical ADHD fashion, I moved on to something else. Then onto the next shiny thing. And the next.

More weeks passed.

Bezgar HP161S with Body

Broken Promises

In the back of my mind, I knew I had to come back to the Bezgar HP161S. I had agreed with you that I would do it, and so much time had passed that I was really starting to feel quite bad about it.

I wanted to make a video that covered how I felt about the truck; a truck that you sent me at no charge for review purposes in particular – but I just didn’t know how to both honor your investment and maintain integrity with my viewers at the same time.

And so, it just sat in storage.

I kept making other videos, and the HP161S just waited, sitting in its box.

Waiting.

And waiting.

Until…

The Catalyst

Just last week, we’d had a bunch of rain. There was mud everywhere. My son was home and bored. And this kid has two settings when he’s playing with RC cars: it’s either off, or the throttle is pinned and he’s got the car in FULL SEND, no matter if it’s a crawler, a trail rig, a basher, a road car – pretty much anything in my extensive RC collection that he’s driven, he’s broken it somehow. He’s the ultimate torture test technician. (There’s probably another RC channel idea in there somewhere).

I didn’t have time to fix up another car for him and I knew I’d finished filming the Bezgar HP161S weeks ago (it’d been months by then but as usual, I’d lost track of time). So, I charged up a 2S battery and put the controller in his hands.

Bezgar HP161S for Kids

Bezgar HP161S Tested

LAUNCH! He punted that thing around our muddy yard. Over the jumps, even off the big ones we save for the 1/8 and 1/5 trucks like the Arrma Kraton and Traxxas X-Maxx. There was lots of face-plant and flat-back landings, all the tumble-wumbles, big hits, full throttle collisions, you name it. He was giggling away and after a few minutes I stopped what I was doing to watch him.

The little Bezgar HP161S was not missing a beat. It was taking the punishment – and I don’t know about you, but the engineer in me can’t bear to abuse my cars. That special check in the mind – mechanical sympathy, you may have heard it called – it just stops me from bashing something to oblivion.

But not so with my boy. Oh, no. He was PUNTING that thing off everything. And the plucky little truck just kept coming back for more! Hard landings on corner wheels and the links and A-arms just hung in there like champs.

The little truck Just. Kept. Going.

Bezgar HP161S Dirty

Eureka!

And in those few magical minutes of watching him dish out Kevin Talbot levels of punishment, I knew I finally had my ‘hook’ for the video. This thing was a tiny terror; it was nothing less than a micro X-Maxx. And I could now put together the kind of video that did this little rig proud.

And then I played with it some more and it grew on me. I discovered some little ways to make it go better, and before I knew it, I was having FUN! What do you know!

So, Bezgar, I’m truly sorry it took me so long to get this little truck into the spotlight. It didn’t deserve the wait, and you have been incredibly patient. You’ve built something truly special here and it might just be one of the toughest little trucks in my very, very crowded RC garage. Well done.

Here’s the video:

BTW, Happy Birthday

Well, happy 5th birthday, Bezgar! Hope your next year in business outshines the last! I’ll be cheering you on!

PS. You’ve just emailed me to thank me for taking so long with the car, getting to know it and for taking the review so seriously. In that case, maybe ignore the above. Let’s go with how serious I am about the car. That makes me look like the hero of this story. I like that much more!

RadioLink RC8X: Your Next Upgrade?

What Came Before

We’re looking at the RadioLink RC8X radio system today, but first, I want to take a short wander back in time with you. The year was 1987 and I had my first hobby-grade radio-controlled buggy in my hands. The radio transmitter was one of those old Futaba dual stick arrangements – still in use today in much of the hobby, but not with cars and their ilk. The transmitter took 8x AA batteries and the receiver took 4x AAs, as well as the NiCad stick pack. It was a tedious affair and though it worked, it was clunky.

In the decades since, I’ve encountered a multitude of transmitters, each with its own quirks and features. I have my budget favorites and there are models I like and ones I don’t. But here’s the thing: there are only so many ways you can make a radio transmitter. People have a variety of ways they want to use one and if you’re in the after-market (as opposed to OEM, being supplied with RTR models these days), you have your work cut out for you: your product needs to be familiar and intuitive enough to use, but different in some way so it stands out and to look good doing so.

RadioLink RC8X Radio & Bag

Enter the Radiolink RC8X!

This radio system is something a little different to previous RC radio upgrades I’ve had. RadioLink sent me their new RC8X handset along with a few receivers to review – you may have noticed it in some of my videos recently (the speed run series and the Redcat Gen9 to name a few). I’m pleased to report that this is not just a new iteration of the same old stuff. This tricky little handset has some features that may surprise you – let’s take a look.

RadioLink RC8X Carry Bag

First Impressions

Straight out of the box attractive carry case, the RadioLink RC8X feels special. It isn’t pro-level briefcase special (keep an eye out for our FlySky NB-4 system review soon!), but that’s a different beast. No, the RC8X feels more like a utilitarian do-it-all model that I’m hoping might be my new go-to for a bunch of my models (I have over 100 in my garage at this point and keeping track of everything is a task!).

The handset’s sleek design is complemented by the 4.3-inch full-color IPS touch screen, framed in burnt-orange LED strips on each side of the base. Radiolink seems to have hit the mark in blending form with function and I really like how this one looks.

One thing that stands out immediately is the hulking ‘PS4’ button at the rear of the radio’s base, or foot. In my testing, I’ve bumped this button repeatedly, so I’ve had to disable it. The good news is this is one of just two negative things I have to say about this radio. More on that in a bit.

RadioLink RC8X Package Contents

A Screen That Does More

The RC8X’s display is nothing short of impressive. Boasting an 800*480 resolution, it promises a smooth screen refresh experience akin to mobile phones. The absence of any lag during fast scrolling is a testament to its capabilities.

And as a neat surprise for FPV fans, the screen doubles up as an FPV display – we’ll touch on that in our video, at the end of this article. It might seem gimmicky, but there are a couple of situations where having this feature is really going to be quite handy. Personally, I’m a fan and I’m going to miss this on other radios from now on!

Customization: A Personal Touch

The system’s designers have outdone themselves with the customization options on the RadioLink RC8X. I have many different systems in my collection and customization is common. However, it’s often a clunky experience and the “limitless options!” from the sales copy often translates to a small choice of colors or layout changes.

I have been surprised at both how easy and how broad the customization is with the RC8X. If you’re like me, you don’t mind how it looks and sounds in stock form, as long as it’s functional. However, given making changes is so easy, you’ll probably be tempted to try it. From system themes to voice broadcasts, the transmitter can be tailored to your preferences. You can tweak background colors, font colors, and function buttons, and it’s easy!

RadioLink RC8X Customization

Voice Broadcast: Keeping You Informed

The voice broadcast feature is a noteworthy addition. It allows for alarms based on various parameters, including low transmitter voltage and low RSSI. These features are fairly standard.

Where the RC8X gets special is with its ability to customize the voice broadcast content. And I don’t just mean a little. I’ve browsed the file system on the removable mSDHC card and found you can completely redo the sounds for this thing. It’s filename-based, so if you were so inclined, you could fully redo the sounds for the RadioLink RC8X and have a radio uniquely your own. It’s pretty cool. The inclusion of a headphone jack ensures you’re always in the loop, even in loud environments.

Performance Metrics

The RC8X promises a ground control distance of up to 600 meters, a testament to its FHSS spread spectrum and 67 channels. More is better here, though the radio must operate within a given band. Having a powerful computer driving the frequency hopping means agile interference-avoidance for maximum SNR (Signal to Noise Radio). This should also be helpful in hilly or otherwise convoluted/crowded environments, as lower frequencies may do better and the radio will adjust on the fly, automatically. We’re talking small improvements, but it all helps. 2.4GHz is already pretty good, but you should notice a difference with a powerful radio system and its various tricks to maintain a good signal.

RadioLink RC8X PS1

Response Time: Precision in Control

A response time of 3ms is close to the best in what’s currently available. Futaba, FlySky and Sanwa have this handset beat with 2ms to 2.8ms best measurements across different models – but I challenge you to notice the difference at 5ms or less. I can speak personally to the feel between +10ms and the faster handsets like the Futaba 4PK or Sanwa MT12 on the track, with a previous comparison I’ve done, but modern premium radios have their own implementations of maxing out response speed and the Radiolink RC8X is one of them. Notably, the consistent low speed is what’s important to track racers and historically, the Sanwa easily beats the Futaba 4PX/K models with consistently low latency. The new Flysky NB-4 and this RadioLink RC8X also show promise in low average speeds, where others have tried and failed in the past.

The way they usually achieve it is with some form of duplexing, at the cost of additional channels. Instead of having 8 active channels, for example, the RC8X will only allow you to have throttle and steering active when you’re at the highest speed. The FlySky NB-4 is similar in this regard. It’s a limitation of physics and what can be achieved with a single transmitter and receiver module, but I’m glad of the choice. Even with all the channels enabled, you still have a snappy system, while when you’re in a race environment you’ll only need throttle and steering anyway. Good compromise!

Telemetry: Data at Your Fingertips

The telemetry feature is a game-changer, offering real-time insights into model battery voltage, RSSI, and receiver voltage. With support for up to an 8S (33.6V) battery, you’re always equipped with the data you need for a safe RC experience.

I’ll repeat that: the receivers can accept up to an 8S battery directly connected to the voltage telemetry port to give power level data to the handset. Even my previous favorite FlySky radios don’t do that. I’ve always needed an expansion module to achieve this. Many people might overlook this seemingly minor feature, but for those wanting the simplest way to stay on top of battery levels in their models without having to add additional sensor module/s, this is a standout feature!

Receivers: R8FG and R4FGM

This brings us to the RadioLink RC8X receivers that ship in the package. Helpfully, it actually includes two distinct receivers:

R8FG: This receiver comes with an integrated gyro, ensuring precise control. The support for high voltage servos further enhances its appeal.

R4FGM: Compact yet powerful, this receiver is designed for smaller RC models without compromising on reliability.

As covered above, I really appreciate that both of these receivers can handle high voltage servos and even gives you feedback on your model’s voltage – the built-in battery telemetry port handles up to 8S direct! Bananas!

If you’re into SBUS, the R8FG’s got you covered. It can output an SBUS signal, making it a breeze to connect.

But here’s the cool part: the RC8X isn’t just limited to the R8FG. It plays nice with a bunch of other receivers. There are these compact 4-channel ones, the R4FGM and R4F, which are perfect for smaller RC cars. Then you’ve got the 6-channel ones like R6FG and R6F, the 7-channel R7FG (which we used in the Rlaarlo Speed Run video series), and even the long-distance champs, R8EF and R8F, which are great for RC boats and possibly speed runs (as yet unexplored).

Adaptability and Power Options

One of the standout features of the RC8X is its adaptability. The transmitter can be powered using various sources, including 8 AAA batteries, 2S-4S LiPo batteries, 6S Ni-MH batteries, or even a computer or mobile power bank via a Type-C cable. The universal JST connector ensures protection against reverse polarity connections.

Sounds good in theory, right? In practice, you’ll want to be prepared, as this leads into my criticisms of this system. Read on…

RadioLink RC8X USB-C

Drawbacks

I mentioned the PS4 button is a bit of a problem earlier in this little chat. I bumped it frequently when filming my various videos for RC-TNT, so I ended up disabling the button entirely. This is a minor annoyance with the design and one you may overlook unless you’re clumsy like I can be!

My other nitpick with this otherwise brilliant system is the radio’s default power configuration. It needs no less than 8x AAA batteries to work out of the box! In 2023, this is ridiculous. AA batteries at least I could understand, as their capacity makes their number more palatable, but to need this many AAA batteries in a power-hungry computer system like the RadioLink RC8X seems like a design oversight.

RadioLink RC8X Battery Compartment

Lemons to Lemonade

UPDATE: it’s come to my attention that if you buy this radio system from Radiolink Direct on Amazon, they appear to ship the radio with a 2S LiPO battery, which neatly solves this issue! Woohoo!

Otherwise, if yours comes with the 8x AAA holder, you could do one of a few things:

  • Suck it up and use rechargable NiMH AAA batteries. They’ll give you a few hours of life at least and hey, you can keep a second set on standby.
  • Remove the AAA battery case entirely and replace with a LiFE or LiPO battery. As long as it has the red JST plug and is 2S to 4S, it’ll work. I’d reocmmend a 2S 1200mAh LiFE or LiPO, as this will fit easily. I’m using a Turnigy Nanotech 1500mAh 2S battery and it fits. Just. This pair will safely fit, and will help keep you powered up with a ready spare.
  • 3D print a larger battery lid for the base of the radio and 3D print or buy a 2x 18650 battery holder with red JST plug (mind the polarity matches the radio’s labels). There are also 2S 18650 LiIon premade battery packs that will fit, as long as you have an extended lid printed for it.

The battery compartment is roughly (L) 92mm x (W) 53mm x (D) 13mm – a bit deeper in places – but if your battery is smaller than that, you should be right.

Ergonomics and Design

Radiolink has paid attention to the ergonomic design of the RC8X. Features like adjustable trigger spring tension, threaded design for better grip, and a lanyard for weight balance showcase their commitment to user comfort. A notable design feature is the ability to reverse the installation direction of the wheel section, making it friendly for both left and right-handed users.

I also like that the wheel can be easily removed and replaced with a 3D printed alternative that comes with a built in thumb steer for one-handed operation. I understand RadioLink sells something like this also, if you’d prefer to get the real deal from the company.
