How to Program HobbyWing Fusion RTR ESC?

How to Program HobbyWing Fusion RTR ESC?

April 2024 – various video comments

Redcat Ascent Fusion: How do you program the HobbyWing Fusion RTR ESC? (or, how to program the HobbyWing Fusion Crawler ESC).

HobbyWing Fusion RTR ESC Programming

A. There are three variants of the HobbyWing Fusion now: the Fusion Pro 2300kv, the Fusion SE 1800kv and 1200kv, and the Fusion RTR (aka. Fusion Crawler) 1800kv. It’s the Fusion RTR that ships with the Redcat Ascent Fusion, and we’ll probably see this OEM-supplied unit in other RTR models in future, too.

You can use any of the programming cards from the HobbyWing WP-1080 ESC (and we have a programming guide for all crawlers for the WP-1080 here), the HobbyWing Fusion Pro, or the HobbyWing Fusion SE. It’s the ESC itself that dictates what each menu does, regardless of the sticker on your programming card.

HobbyWing Fusion RTR ESC Programming Menu

First, remove the rubber water shield on the power button module and plug in your HobbyWing programming card. There’s an illustration to show signal, +ve and -ve (white, red and black, in that order).

Press Power to turn the ESC on. The card’s red digits should illuminate. Here’s what each menu item is:

  1. Low-Voltage Cutoff (LVC) for LiPO batteries (1-4; 1 is Disabled (for NiMH batteries), 2-4 is low-high, maybe 2.7v, 3v and 3.3v at a guess);
  2. Motor Rotation (1 CW, 2 CCW);
  3. Drag Brake Force (1-5; 1 is off; 2-5 weak-strong drag brake);
  4. Drag Brake Rate (1-6; slow-fast application of drag brake).

Press Item to cycle through 1 to 4, Value to cycle through the item options, then when you’re done with all of them, press OK to save.

Press the power button to turn off the system.

Unplug the programming card, replace the rubber water sheild, and power up – you’re ready to test!

Redcat Gen9 Scale Trail Truck

Redcat Gen9 Scale Trail Truck

​A Detailed Look at Redcat’s Latest

The Redcat Gen9 is the long-anticipated successor to the Gen8 V2. We had to wait a while in Australia to get it, but now it’s finally here! This new model is more than just a Gen8 V2 with a different body. It’s a whole new beast, sporting a new Scout model body and a host of updated features underneath. Let’s dive in and see what makes the Gen9 a worthy addition to the Redcat Racing lineup.

My favourite global hobby store, AsiaTees, sells both the blue and gray variant of this lovely new rig. And on Amazon, TREAL already has a bunch of shiny new goodies for it.

Redcat Gen9

What’s New with the Gen9?

The first thing you’ll notice about the Gen9 is its new body, modelled after the International Scout 800A. This model is slightly smaller than the Scout II, which allowed Redcat to tweak the front and rear bumper setups and enhance the already impressive approach angle performance of the Gen8. But the new body is just the tip of the iceberg.

The Gen9 also boasts a two-speed transmission, V3 portal axles, new tires (that look suspiciously close to the tread on the Marksman we reviewed last year), beadlock wheels, and an entirely new body mounting system, not seen on any other rigs to date. There’s an interior now, too – a big jump over the previous models in the series. If you’re a fan of the Gen8, you’ll find many familiar parts in the Gen9. Even as a Gen8 V2 owner myself, there are plenty of new features or updates to make the Gen9 a worthwhile investment.

New Gen9 Transmission

A Closer Look at the Gen9 Body

Redcat has upped the ante with the design and construction of the Gen9 body, thanks to their experience with their R/C lowrider lineup. The Gen9 International Scout 800A body is a multi-part piece that offers a detailed interior and exterior with ample room for customization. The open-cage design provides an excellent view of the interior, which includes a steering wheel, shift levers, door handles, and pedals. The only other trail rig that offers this level of scale detail is the SCX10 III Early Ford Bronco and some of the Cross RC models, such as the EMO XT4 (which we have here but it’s unbuilt – must get around to that one!).

The exterior of the Gen9 also features scale details, but they may not be as durable as you’d like. Side mirrors and door handles add visual interest to the body, but they may not withstand rough handling. Our unit has arrived intact, but I’ve read of numerous others who’ve received broken mirrors or door handles out of the box. Thankfully, Redcat includes a few extra parts in case you need them. I’d suggest keeping the mirrors aside until you get your rougher trail driving done! (Or look at hinged or rubber alternatives, like this handy 5-pack).

Redcat Gen9 Hinged Body

Lights and Colors

There are light buckets for 2x white LEDs on each side up front, and 1x red and 1x white reverse LED on each side of the rear. The side signals at front and rear of the body are stickers only. But, there are also two light buckets behind the dash! I’ve just gotta work out how to open it all up – it isn’t obvious and the manual gives no clues. I’ll cover this in a future video and/or article here on rc-tnt.com.

The Gen9 body comes in two color options: Metallic Blue and Graphite. Both are eye-catching, and Redcat includes two decal sheets so you can personalize your rig right out of the box. There aren’t instructions included but the box art gives you some idea of how you might go about it. You could also image-search the web for ‘IH Scout II’ for some inspiration. The body mounting system has also been redesigned, making it easier to access the internals of the rig. Two swivel latches secure the front of the body, and releasing them allows the body to be tipped toward the rear and removed from the chassis. Some have noted the front swivel pins can get loose with driving, but ours have been firm so far!

Under the Hood: The Gen9 Chassis

At first glance, the Gen9 and Gen8 chasses may look similar. Both feature a traditional H-ladder setup with full fenders and sideboards. The motor and transmission are in about the same spot. But a closer look reveals a small shift servo for the two-speed transmission and rock light ports on top of every inner fender. The portal axles have also been adjusted to improve durability, tracking, and steering performance. There’s a new servo, too! More on that in a moment.

These updates may not be visually striking, but they significantly impact the Gen9’s driving experience. The truck’s weight is certainly hefty for a ready-to-run (RTR) model. It’s heavy, at about 4kg, but the weight distribution is reasonably low and centered. The car is a little roll-over happy, but it’s not a chronic issue. That is, until you start making turns in 2nd gear! That’s another story.

The most significant performance change between the Gen9 and its predecessor is the two-speed transmission. The first gear is similar to the standard gearing of the Gen8, which is great for crawling but leaves something to be desired for trail use. This is a big point for the Gen9 over the Gen8, as second gear offers a fun, faster than walking speed experience. This feature is great for trail enthusiasts or those who want to let loose occasionally. Just don’t get carried away or you’ll be buying new side mirrors!

Redcat Gen9 Chassis

Redcat Gen9 Wheels and Tires

The Gen9’s tire choice is another departure from the Gen8. The Redcat team chose a 1.9″ version of the Interco Super Swamper SS M16, and I’ve just gone and looked – yep, it is the same tire found on their 1/8-scale TC8 Marksman, but in 1.9 instead of 2.2. This tire offers reasonable traction for both crawling and normal trail use. The wheels have also been updated with a faux outer beadlock ring for added scale. The actual bead locking is achieved from the rear of the wheels.

The tires of the Gen8 were fairly poor. We did a big tire test in 2021 that covered the Swampers from the Gen8 and they came up poorly overall. We do have an upcoming ‘biggest on YouTube’ tire test this year that’ll test more tires than ever before in one series and we’ll include this set in that test for reference. I’ll update this article with a link when it’s done.

The Gen9’s Radio System

DumboRC has been making its way into many RTR configurations over 2022 and 2023. It’s good to see Redcat jump onto this as well. The Gen8 V2 came with the AFHDS protocol of the older FlySky system, which made it inconvenient for binding to newer radios. Now that DumboRC is commonplace, there’s a heap of flexibility out of box with this system.

You not only get the 5-ch receiver with the Gen9, but it’s the light-control variant as well, with an entirely separate, dedicated row of pins just for LEDs in the car. On the transmitter, only three channels are active in the default configuration. You can easily add a fourth and there’s even a Channel 5 dial under the cover of the radio. I’m unsure if this works yet, but when I get to testing it, I’ll update the article (yep, Ch5 is a dial-controlled channel with full functionality). The third channel controls the two-speed transmission servo via the left blue button on top of the unit. The two auxiliary channel buttons are easy to find and use, and they light up when activated, so you can easily tell what gear you’re in. Good!

Redcat Gen9 Moving Parts

Portal axles grant clearance without hurting center of gravity too much and the metal diff plates are a nice touch. If construction and materials are at least as good as the Gen8 V2, then this drive train will be a solid and reliable performer.

There’s finally a better servo for steering than Redcat has done before – see the woeful unit on the Marksman, for example. They’ve been underwhelming for a few years now. To finally see a metal geared, metal cased, waterproof and 8.4v capable unit is awesome. It even gets to 42kg/cm of torque at 8.4v – what a turnaround from Redcat’s previous fare!

Drive shafts are plastic but tough. Axle components are also solid and the stainless steel links and ball ends are stainless steel. It’s a decent package all round, especially given the price. Even if this rig was $449, this would be a positive review of this vehicle. But the model is surprisingly good for its RRP of just $399 (and selling for less from some dealers).

Crawling and Trail Performance

The Gen9 shines when it hits the trail. The two-speed transmission is a standout feature, as the Gen8 was either fast and bad at crawling or slow but frustrating on the trail. The simple addition of the 2-speed is a winner. The first gear is perfect for smooth, low-speed crawling, while the second gear lets the rig move at impressive speeds. Despite its weight, this rig can really move.

When it comes to crawling performance, the Gen9 is excellent. After the Gen8 V2 was capable but not exceptional out of the box, the Gen9 has been a real surprise. I’d put it nearly on the level of the TRX4 Sport. The 1.9″ Interco SS M16 tires have an aggressive tread pattern and a high grip compound, allowing the rig to navigate obstacles with ease, even in challenging conditions. They’re not the all-rounders of the Traxxas Canyon Trails, but they’re a real improvement over the Gen8 V2’s tires. (See our Gen8 V2 review here). For more on performance testing, see our video (posted at the end of the article once it releases).

Final Thoughts on the Gen9

The Redcat Gen9 is an impressive machine at an impressive price. For USD$399.99, you get a capable crawler and trail truck with features typically found in higher-priced models. It’s a great 1/10-scale rig for outdoor driving, whether in your yard or on the trail. With plenty of room for customization, the Gen9 offers solid performance and stunning visuals. That’s a win-win in our book.

Redcat Marksman 1/8 RC Crawler

Redcat Marksman 1/8 RC Crawler

What Is It?

The Redcat Marksman is a different RTR RC crawler in more ways than its 1/8 scale size. It sports a (mostly) decent electronics package and 2.2” wheels. A pretty body with paint on the outside gives the polycarbonate body an interesting finish.

Whilst not a flawless execution, there’s a compelling case to be made for price to performance, especially if you’re after a trail-oriented rig. Join us as we take a closer look at this interesting, larger-scale crawler.

How Big Is It?

For some comparison, we’ve put the Redcat Marksman between a Traxxas TRX4 2021 Bronco 1/10 and an Axial SCX6 1/6 RC crawler. Note that while the Marksman is similar in length to the TRX4 Bronco, the track width is considerably greater on the Marksman. Also, the overall vehicle size is similar to 1/10 scale rigs, but width is the greatest difference – if a little less than obvious at first glance.

The vehicle doesn’t weigh more than many 1/10 scale crawlers and its close enough in ‘feel’ that you could reasonably trail this with others driving 1/10 scale rigs and fit right in. Certainly, some rock problems that might defeat the Redcat Marksman may be traversable by smaller rigs on account of that track width! More on performance in a bit. First, let’s look at what you get with this RTR model.

What’s In The Box?

There’s the vehicle itself, the radio transmitter, manual, scale accessories and ESC programming card. The Redcat Marksman is a Ready To Run (RTR) model, which means all you need to get it going is a battery for the rig and 4x AAs for the radio transmitter. The included Electronic Speed Control (ESC) is a HobbyWing WP-1080. This gives you the flexibility to run either 6-to-8 cell NiMH or 2S or 3S LiPO batteries.

Redcat also includes an accessories bag with some red plastic scale parts – though no obvious way to mount these to the body. There’s a spare wheel adapter for the back of the body – pictured below – but no spare wheel. We’ve used an old Axial Trepador from the original SCX10 on ours as its nice and lightweight and still looks convincing near the Marksman’s larger tires.

Radio System

The radio is the standard rebranded Flysky FS-GT2E AFHDS 2A transmitter, though the sticker calls it an RCR-2CE. This is the 2-channel unit Redcat Racing uses on their entire ground model range at present (2021 and 2022).

One nice thing to note is it runs Flysky’s AFHDS 2A protocol, so if you already have a FS-GT5 for other models, you can bind that to the Marksman here as well. The radio feels good in the hand and has a nice feel on the wheel. There is a sufficient, if sparce, amount of adjustment on the dials and it isn’t heavy. Overall, a good basic radio.

Holmes Hobbies For The Win!

The brushed motor in this machine is a Holmes Hobbies Crawlmaster Sport. This is a 13-turn 5-pole (or 5-slot) 550-sized motor. Being a 5-pole means you get buttery smooth torque at the expense of the punch delivered by 3-pole motors. On a crawler, this is generally desirable.

For trail use, the motor is a perfect choice. There’s sufficient speed for trail driving and still enough low speed control to be satisfying on the rocks. However, we found that if you’re more biased toward crawling than trailing with this rig, a motor with slightly more turns may give a more rewarding experience.

After some testing, we’d recommend the 16-turn 550 Crawlmaster Sport and the same gearing. On 3S power, you’ll be all set with long runtimes, good low speed control and more than ample speed for trail driving. If you keep the 13-turn motor, going down one tooth size on the pinion and sticking on 2S power could also be a reasonable way to slow it down enough to feel a bit better on trickier rock problems. Of course, this is largely a case of personal preference and the stock configuration is fine.

Redcat Marksman Motor

HobbyWing Is Good!

We have a good, solid radio system and a workhorse motor. Redcat have opted for a high-quality ESC for the Marksman in the HobbyWing WP-1080. This is a popular ESC for good reason. It delivers smooth and reliable control and is very customisable. We like this ESC so much that we’ve written an entire how-to article for programming it, right here on rc-tnt.com!

You can use the stock settings for the most part, but we would recommend making one change in particular before running it. Enable freewheeling, which is option 15 on the programming card. Set that to 1 instead of 2 and you’ll effectively have an active drag brake. That means the WP-1080 will apply braking to the wheels even while you’re giving throttle input, helping to hold the vehicle on a hill at the speed you’re indicating, rather than allowing the rig to run away down the hill. A good thing!

Redcat Marksman ESC

Servo Avoido

The electronics package with the Redcat Marksman is excellent! That is, until you come to the servo. This is the same Hexfly 25KG 4.8v-6.8v unit that Redcat puts in most of their vehicles, even their diminutive 1/10 short course truck (which is really a 1/12 sized machine). The servo is slow and too weak even on the smaller Redcat Gen 8 V2, we’ve found. That they’ve also put it on the Marksman leaves one wondering if they’ve actually, y’know, tested the big rig with it. Because it isn’t good.

If you change just one thing on the Redcat Marksman, make the servo your first upgrade. The WP-1080 has an adjustable BEC and while it comes at 6V by default, you can change that to 7.4V with an upgraded servo and the Marksman will be worlds better. Seriously, budget for this if you plan to buy this rig.

Nearly any other crawling servo would be better. Here are a few options we use and recommend, from cheap to expensive:

  • JX Servo WP-5318HV ~16.5kg @ 7.4v, waterproof, cored, metal gear (lower rating but much better than the stock Hexfly unit).
  • JX Servo CLS-6336HV 35kg @ 7.4v, waterproof, coreless, metal gear.
  • JX Servo BLS-HV7132MG 32kg @ 7.4, splashproof, brushless, metal gear, alu case. (Fast and doesn’t fade under heavy load. Probably our favourite semi-budget crawler servo).
  • JX Servo CLS-HV7346MG 46kg @ 7.4v, waterproof, coreless, alu case, metal gear.
  • Holmes Hobbies SCX500v3 ~42kg @ 11.1v (direct run from 3S), waterproof, brushless, ultra tough – our favourite comp servo!

Body and Accessories

In a break from the usual, the Redcat Marksman sports a polycarbonate body that has been painted on both sides! The matte green finish on the outside looks very smart. They’ve finished the inside of the body in a rust-brown color. If you think about it, as the outside green paint gets scratched off on rocks and branches, the underside’s brown will gradually show through, giving the appearance of rust! Very clever little scale-ageing trick they’ve incorporated there!

There are light buckets for headlights only – taillights are stickers on this body. The plastics and faux interior on the Marksman are all of a high quality. Finish is solid and this body should last well. It’s very attractive and is enhanced further by the spare wheel holder included in the accessories package. We’ve mounted ours and the weight difference is minimal on a bigger crawler like this, so we found it very worthwhile for the improved look. You do have to poke a few holes in the pretty body to add this extra bit, so think about it before you do it – but we can at least show you how it looks. We like it!

Redcat Marksman Scale Accessories

Chassis & Running Gear

The steel C-channel chassis rails are solid. Reinforced with plastic cross-braces, the Marksman has a nice, rigid feel. We like that the vehicle doesn’t weigh a lot, despite its size, and as you can see from the photo below, there’s a lot of spare room on the chassis. Included wheel wells are a nice touch also – you get the aesthetic benefits when the body is on, and they also work to keep crud and debris out of the internals.

The axles are solid and well designed. They’re straight rather than portals, which is nice to see when portals seem to be everywhere. You’re going to be scraping the diff pumpkins over rocks, given the width of the vehicle. Larger tires are helpful, but clearance will be something to keep in mind when driving. For us, this adds to the appeal of scale fun. The skid plate is also intelligently implemented and has a nice, smooth finish. Drive shafts are tough plastic with steel universals. All up, the Marksman is a strong and lightweight platform. Simple and reliable.

Redcat Marksman Chassis

Drive Feel

We said earlier we found this vehicle to feel a little faster than we’d like on the rocks. On the trail, the speed is good and it turns well at speed – impressive given its size and locked axles! The adjustability from the WP-1080 ESC means you can make the Marksman feel more like a cruisy trail rig or a precise rock crawler. It’s nice to have that control.

Another thing to note is torque twist. This is the phenomenon where the chassis twists under throttle in the opposite rotational direction to the drive shafts. It’s quite pronounced on this vehicle. On a smaller rig, torque twist can unsettle a crawler significantly. While it’s pretty pronounced on the Marksman, even to the point of lifting a wheel at times, the whole machine does not lose its track or become unsettled. It could be that the effect is weakened by its greater wheelbase and track width than on 1/10 crawlers. Something to be aware of, then, but not a deal-breaker.

The only let-down in the rig is that weak Hexfly servo. We almost never say this as we don’t like to waste things, but do budget in a better servo when you buy the Redcat Marksman. It’s the only shortcoming we’ve found after running several packs through it.

Our Verdict

This is a mid-range crawler as far as pricing goes. You have the choice of numerous 1/10 scale crawlers for similar money. If you like the idea of walking a trail and crawling obstacles as you find them, the Redcat Marksman could be for you. It’s not as capable as some 1/10 scale crawlers largely on account of that track width, but it’s a lovely, smooth machine. We haven’t driven it enough yet to give an idea of longer-term durability but will update this section in a few months to note this.

We love its look. Its simplicity under the body is alluring and it feels great on the rocks. What do you think? Feel free to leave comments and questions in our review video above and stay tuned for more videos in future on the Marksman’s performance, what upgrades we do (*cough* servo *cough*) and how we find its durability. After a few LiPO packs so far, we really like it.
