FMS Chevrolet K10 1/18 RTR Crawler

FMS Chevy K10

If you’re into American pickups from the 70’s and you’ve been thinking about a smaller scale crawler, your search is over. The FMS Chevy K10 scale RC crawler is a gorgeous, licensed hard-bodied model with moderate performance to match its looks.  It’s an RTR (Ready To Run) and you only need to supply 4x AAA batteries and a USB 5V 2A charger to get going.

FMS Does Impress

We were recently impressed by the FMS Suzuki Jimny 1/12 model, with its exquisite scale detail inside and out. The FMS Chevy K10 is a little over a foot long and enjoys nearly the same level of detail on its body. The underside is tidy and the interior reasonably accurate, though somewhat more spartan than the Jimny. The price is accordingly lower than the little Suzuki and we think there’s a lot to like in this model. Let’s take a closer look.

1970s Hard Body

This model is all about the body. FMS makes a few other similar models with the same running gear and different tops. There’s a Hilux and FJ Cruiser, among others. The FMS Chevy K10 here has a lengthened rear to suit the long bed of this classic pickup truck. That means the trailing arms, drive shaft and chassis are longer than the others. This hurts performance, but oh boy, does it look good! Worth the trade off? We think so!

You get a shiny exterior, complete with chrome bumpers, grille, mirrors, and period-correct wheels. Black plastic door handles and wipers add to the scale detail. This thing just looks amazing when it’s rolling outdoors.



There is a pair of headlights in the FMS Chevy K10 that are pleasingly round and yellow when on. They have a standard light and high-beam setting. Underneath these, a pair of indicator lights are located just above the bumper. These can be set to flash with the corresponding steering direction like faux indicators, or to be set to ignore steering entirely, or to stay on in hazard-flash mode.

The rear of the tray features red brake lights that light up when the vehicle is in reverse. There aren’t taillights nor brake lights. Reverse lights should be white, but they are red. It’s forgivable, as they look great and aren’t distractingly incorrect; just a little incorrect! The car still looks fabulous.

The FMS Chevy K10 features a Chassis Mounted Servo (CMS). This setup hides the 1kg servo up and away from the front axle, helping to add to the scale appearance of the rig. There’s an 050 sized brushed motor, lights at each end and an all-in-one ESC, Receiver and Light Controller located in the engine bay area. The 2S 380mAh LiPO battery goes here too, along with the power switch. A 1A USB LiPO balance charger is included with the model.

The ESC is a 20A brushed unit designed to run on 7.6V. Note, no part of this vehicle’s electrics is waterproofed. There are ways to do this without buying different hardware components, but be aware of this break with the current norm in the hobby. Lack of waterproofing aside, it’s a tidy setup and everything works well together. However, the radio transmitter needs a little more explanation – read on.

FMS K10 Electronics

Radio Transmitter

It’s small in the hand and easy to operate. We found the springs under the 4x AAA batteries weren’t stiff enough and the radio would power-cycle and need to reconnect with the vehicle if it was shaken too much. Also, whilst there are many buttons on the transmitter and the appearance of 6-channels (including beeps when pressed), most of the extra buttons don’t serve any purpose with this model.

Confoundingly, there are several features programmed into this handset that do require extra buttons, but instead of using those Ch-3, 4, 5 and 6 buttons, the functions are instead accessed via multi-purpose buttons with the help of a Mode A/B switch. In Mode A, your Throttle Trim and Steering Reverse buttons work as labelled, but in Mode B, your Throttle Trim + button cycles through the light profiles while the Servo Reverse button acts as a steering end-point limiter, cycling through 30%, 50% and 100% of steering range. It’s not an intuitive system – but once you understand these functions, operation is easy enough.

The shiny chrome wheels perfectly suit the K10 body. The axle width is just right, and that soft rear suspension means the rear wheels tuck right up into the wheel well with articulation – it looks just like the real thing! The licensed Cooper Discoverer STT Pro tires complete the look for a stunning finish.

In real life we’ve been driving on Cooper tires for years on our 4WD vehicles. The 80-series here ran the Discoverer STTs and the 100-series is currently rolling on the Discoverer ST MAXX variants. We haven’t used the STT Pros before, but the Discoverer range is known for its rock ability, particularly for steep ascents and descents. This is a seemingly perfect match for the intended purpose of this plucky little model. Love!

Shocks, Coils & Links

Coil-over springs around plastic ‘friction’ shocks comprise the suspension on all four corners. The front shocks are nearly upright. The rears are laid forward at around 45 degrees – this ensures they fit under the bed. The laid-over shocks give the rear a very soft, bouncy character. Stiffer springs could help, but ultimately, laid-over shocks at such an angle give a diminished response part-way through articulation. This will compromise handling if you’re carrying anything in the tray, but on the plus side there is plenty of plush movement to help keep wheels on the ground in the slow and rocky stuff.

The links are a different matter. There’s a 4-link setup at both ends. This makes sense for the rear. There is the same 4-link setup in front, which would make sense if there was an axle-mounted servo. However, as this is a CMS vehicle, a panhard rod is required to ensure the suspension can cycle without lateral movement, which would otherwise compromise steering input. A panhard system works best with a 3-link arrangement, comprising one upper link rather than two. Panhard and CMS will work with a 4-link setup, but not so well as with 3-link. We think one of those two upper links should be removed to allow proper and smooth articulation of the front axle. We’ll cover this in more detail in a follow-up video where we address a few minor issues with this vehicle. Stay tuned for that. In the meantime, the system works well enough as-is and we were able to enjoy it on the rocks.

Rock and Roller

Speaking of rocks, we took the FMS Chevy K10 to a favourite local river spot with large, round boulders and long slabs of rock. This is perfect terrain for a vehicle such as this. We enjoyed steep ascent and ascents, steps, side-hilling and (very) shallow water crossings. (Incidentally, the ball-bearings in this vehicle are not sealed. Along with the electronics, you’ll want to avoid water in your adventures whilst in stock form).

Gearing and motor size seem well matched to the intended purpose. The servo has sufficient strength and speed to handle such terrain. The radio was comfortable in the hand and the vehicle’s speed was a good compromise between low-speed torque and high-speed running. This thing will go happily at walking pace and still be able to bog right down on challenging obstacles with sufficient torque to turn the wheels. In a word, driving the K10 is fun.

The Verdict

The last FMS model we looked at was the Suzuki Jimny. This was a pleasant surprise, with a great mix of hard-body and scale features and able to deliver a reasonable off-road driving experience. This set the expectation for the Chevy K10 reasonably high.

Did the K10 deliver? We’re glad to report that it absolutely did! If you’re a fan of 1970s square style pickup trucks and you’re interested in a vehicle in this size, the FMS Chevy K10 should be on your short-list. We really like this thing! Check out our video review to see it in action!

FMS Suzuki Jimny 1/12 4WD RC Crawler

FMS Jimny by ROC Hobby

If you’re into hard-body crawlers and highly-detailed scale, is this the car for you? (Spoiler: yes, yes it is!). Made by ROC Hobby, in conjunction with Eachine, this is the FMS Suzuki Jimny – and it’s gorgeous! The vehicle is branded by official licence from Suzuki Motor Corporation Ltd. This lets the factory bring us scale detail at a pleasing level, right out of the box. Let’s take a closer look!

A Very Scale Model

We recently looked at the Jimny look-alike from RGT. It was a performer (for its size) and it had a lovely scale body. But now we have the FMS Jimny here the RGT is looking decidedly less scale in comparison!

The RGT was a mish-mash of different scale ratios. The track and wheelbase were inconsistent with the full-size vehicle and the body was a different scale again. We covered this in the article and videos for that vehicle – check them out if you haven’t seen them yet.

In contrast, the FMS Jimny is consistent in its overall dimensions, in and out. This does limit its off-road performance, but that’s a feature rather than a bug.

Scale Exterior

From bumper to bumper, the FMS Jimny sports a stunning array of accurately reproduced scale parts. The bumpers themselves look like the real thing, with integrated lights at both ends. Real mirrored glass adorns the flexible side mirrors. Under an opening hood you’ll find an engine bay filled with faux engine parts – not just a cover hiding the electrics! The battery and power switch live here, too.

The 3 doors open and there is a pleasing amount of scale trim adorning the body exterior. Flip the vehicle over and you’ll find a convincing appearance of the real car underneath, too. Just have a look at this!

Let’s Take This Inside

The scale party continues once you open a door and peer inside. The doors themselves have an inner skin with arm rest, non-functional window winder, open lever and map holder. The rear barn-style door also incorporates an inner skin with an approximation of the real thing. There’s also a wire pair visible near the hinges that goes up into the integrated tail and brake light at the top of the rear window – which also has the demister lines across it!

There’s a lidded storage compartment behind the rear seats, which independently fold down. The front seats both fold and slide forward and back. The dash is fully detailed with labelled dials and radio. Best of all, the steering wheel moves in conjunction with the front wheels! Just fit your 6” figurine in the front seat and you’re set for some real fun with suspension of disbelief intact!

A Bright Idea

Part of the appeal of the FMS Jimny is its slick light kit. The 3-in-1 radio-ESC-light controller gives tight integration with throttle and steering inputs, plus a separate channel to change light profiles. There are several settings from which to choose (manual except with light control outline here).

The lights can be found in the front and rear bumpers, the front grille, side quarter panels for indicators and the aforementioned tail-and-brake light in the rear window. The system works very well and adds to the scale experience in day and night driving.

Walk and Crawl

With those tiny 60mm tires and limited suspension articulation, you won’t be crawling any major terrain. But that’s okay, as the FMS Jimny is clearly intended to bring you more of a trail drive and light-obstacle clearing experience. The car includes a 180-size motor with appropriate gearing and power for the car’s size and scale nature.

In second gear you get walking speed from the car. That’s just fine for taking it along the trail. Then drop it into first for the harder obstacles and you have a decent little crawler. Limited in tire and suspension, sure, but still quite able if it can get sufficient traction.

Suspension & Geometry

Just like the real thing, the FMS Jimny sports live axles front and rear. There is three-link suspension (ie. with panhard) at each end, which is great for realism but not so much for performance! Again, given this is a scale machine, that is more than forgivable.

There are coil springs on all corners and angled shocks too. The shocks are not oil-filled and really their only purpose seems to be to limit the maximum articulation before the links reach the end of their throw. Without them, the coil springs could pop out. Still, the lack of proper shocks leaves the Jimny to bounce quite a lot on the bumpy stuff. Everything’s built to a price and in this case, the lack of proper shocks seems a logical place for some compromise.

Battery & Charger

The car comes with a USB balance charger that needs 5V and 2A. It outputs the required voltage range to charge the included 2S LiPO battery via its balance plug – that is, ~6v to 8.4v, at 1A. This means the 380mAh battery should be able to charge in 20 to 25 minutes, which is absolutely fine for a ‘cheap’ included battery system.

Note, the battery charger does not have a Storage charge program, so you want to try to keep this battery at around 7.4v when you’re done with it. For reference, empty is about 6.6v and full is 8.4v, so if you run it for 2/3 of the usual runtime before you put it away, that’ll be much better for it than storing it full or empty. It’s a LiPO thing.

Radio & DIP Switches

The little radio takes 4x AAA batteries. It’s comfortable in the hand and the steering wheel has a pleasing and precise spring and movement. There are end point and trim dials for throttle and steering, a 2-way switch for channel 3 (that’s high and low gear) and a button for channel 4 (to cycle through the light profiles).

There is also a set of 4 DIP switches on the top of the unit. These are all two-position switches whose functions are not listed anywhere in the included manual, so here are their functions:

  • Switch 1: driving profile (down is forward/brake/reverse; up is forward/reverse with no brake)
  • Switch 2: battery profile (down is for LiPO with Low Voltage Cut-off; up is for NiMH with no LVC)
  • Switches 3 & 4: drag brake (3 Down 4 Down 25%, 3U4D 50%, 3D4U 75%, 3U4U 100%)

Finish & Durability

The FMS Jimny ships in an attractive EPP case. Being a hard bodied vehicle, the protection works well and the car arrives in good condition. Our unit had loose screws in the roof, with one screw out and the second rear one half out. Both of these were easy to screw back in (1.5mm hex driver) with threads intact. Our RHS side mirror was also loose, but that was easily tightened via the screw on the inside of the RHS door.

There was protective film over the windows and the wiring and electronics were tidily installed from factory. The car is designed in such a way that the fixings should not come loose with use, but if they do, everything is accessible without fuss, though you’ll need your own tools. The car will last as long as its driven as intended. Don’t push things too hard with rock crawling or running second gear in hard terrain and everything should serve you well for a long time.

The Verdict

Is it a rock crawler? Well, kinda sorta. Is it a trail truck? Also kinda sorta. Scale is the focus here and while there are some interesting bells and whistles like the steering wheel and light system, nothing is waterproof and the tires are not aggressive. The steering servo does have sufficient torque for the model and the motor is well matched to the transmission. Some pros and cons here – so where does that leave the prospective purchaser?

If you like scale and the smaller size of this model appeals to you, definitely pick one up. If you’re after a scale experience in 1/12, you will not be disappointed. However, if you want more capability in the rough stuff but you still want something in this size and with a moderate amount of scale, you might instead want to check out something like the MN86KS or the WPL C44KM. As for us, we’re gonna get this thing out and maybe even improve it a little – we’ll let you know!
