How to Install RCRun RUN80 Steering Wheel

May 31, 2023 – video comment from Oliver Walther

Could you give some information how to install the RCRun RUN80 steering wheel servo? I’ve got my kit and for the steering module there are only two alloy pullies and the micro servo. No frame for the servo or other stuff. I hope you could help. Ty from the other end of the rc world (germany) 😉

 

A. The RCRUN Run80 Landcruiser 80-Series body interior (available here) includes a steering assembly that steers with the steering servo input. (You can see a gif of this below). There’s a micro servo that is used to achieve this and it operates via a 1:1 pulley system inside the dash. The micro servo sits inside the plastic mold shape, but there’s no obvious retention mechanism for it.

You need to affix the servo to the bottom corner of the dash mold, and then align the two pulley wheels so the servo can turn the steering column. The whole mechanism is kinda weak and there is slop in the system, but it does work. It doesn’t have to work very hard, thankfully. (And if I was going through all this again, I probably would not worry about having the moving steering wheel – it just adds complexity and noise and you can barely see it when the car is driving – though it is definitely cool, which I totally do get).

Anyway, see below for a couple of photos I took of mine. I secured the servo with a bit of hot glue but you could use double-sided tape or some other glue and it should be fine. Hope that helps make it a bit clearer! We’ve got more general info about this amazing vehicle on our write-up, right here on the site.

RCRun Run80 1:10 Scale Land Cruiser RC Crawler

RCRun Run80 1:10 Scale Land Cruiser RC Crawler

The RCRun RUN80 is a scale Toyota Land Cruiser 80-Series 1:10 model. It’s a builder’s kit that’s ready for assembly – but you’ll need your own electronics, wheels, tires – AND body and interior! Thankfully it’s all readily available and it’s a fast and enjoyable build. When you do the measurements, it’s actually quite close to 1:9 scale rather than 1:10, but all the same, it’s a beauty!

Unboxing & Presentation

The box is very protective of the metal chassis kit within, ensuring the parts arrive to you just how they were packed. Finishing on parts is generally excellent, though the transmission fit and finish left a little to be desired – nothing deal-breaking though! More on that in a bit. First, the overall model itself. This is a wonderful, wonderful kit.

The price from various vendors, at least at time of writing in mid-2021, is around USD$350 to $400, depending on where you look (and on stock, shipping etc etc). We’ve found AsiaTees to be a consistent and reliable online store and have been buying from them for years, long before RC-TNT was ever conceived. We got ours from them – they sell the RCRun RUN-80 LC80 Kit (affiliate link) and the Team Raffee Co. LC80 Hard Body, along with a good selection of wheels and tires in 1.55″, 1.7″ and 1.9″, depending on your preference for this build. Find a full list of items we used, and where to get them, at the end of this article.

RUN80 Wheels & Tires

Most RC Crawler kits don’t come with electronics and the RUN80 is no different. Like the SCX10II Raw Builder’s Kit and the HPI Venture Builder’s Kit, this one also does not include wheels and tires, which is great for choice and economy, but can be disappointing if you’re unaware until you build! Thankfully, wheels are plentiful, varied and quite affordable, particularly if you look at the Sunraisia style steel rims that are so common on Landcruisers in Australia and the Middle East. If you prefer USA-style wheels to match the petrol models instead, of course you’re still covered. Pick your standard 1.9″ wheel of preference and you’re away. The kit does include hexes, pins and nuts, so you just need the actual wheels and tires and you’re set.

RUN80 Axles Links

Realistic Axles, Links & Suspension

The suspension setup at each end is very realistic. The coil springs themselves are floating with rubber stops at each end, with the shocks just in front or behind, as on the real vehicle. The upper and lower arms are roughly scale – certainly much moreso than any other model on the market, if you’re going for scale faithfulness to the real vehicle (and the author owns a Landcruiser 80 series, 1HZ, to which comparisons are being made!). The diffs aren’t quite in the right spot as far as horizontal alignment is conecerned, but they’re close enough to be convincing to all but the most critical eye (did I mention I’ve been looking under my 1:1 rig for this review?). Overall, axles, diffs, suspension and links are Very Good as far as scale is concerned. Functionally, they offer about as much range of movement as you’d expect from a well setup full-size vehicle, which for scale driving means some limitation, but it will still be a capable model, if heavy.

RCRun Transmission

This is a single-speed gearbox. That means you’ll want to be thoughtful about the motor and pinion, the latter of which ships with the model (14T 48P). I used that pinion and a Hobbywing AXE 2100kv brushless system – and it is so very nice! If you were taking the more sane route for this vehicle, remembering it’s a single-speed, the Hobbywing WP-1080 would be the brushed ESC to use, along with a 35T or 45T 540 motor. A 550 will fit but you’ll need a hacksaw to help with length – no huge deal, but worth keeping in mind.

Unfortunately, the motor housing itself didn’t make such a great first impression; if you’ve watched the video, you’ll be aware that the screws in our model were over-tightened on the motor housing/transmission assembly. Quite a few of the threads were stripped and needed re-tapping in a slightly larger size. I always keep the tools around for such eventualities, so it was a trivial fix, but disappointing all the same. The gears themselves were seemingly of a high quality steel and the bearings are solid. The motor mount is thoughtfully designed and getting the pinion and spur gear mesh sorted was easy.

Once the transmission is together, you’ll get to the driveshaft assembly. These are also of a reasonably nice alloy, but while I can’t prove this with the equipment at hand, I suspect they’ll be of moderate strength rather than the super-strong, hardened steel of high quality machined parts from more expensive models and hop-up parts. For what you’ll likely be doing with this model, though, they’re a completely fine accompanyment.

RUN80 Diffs

Run80 Body Mounts

Although the body needs to be bought separately to the kit, they are designed to go together and so I’ll cover the body, interior and accessories in this review. You want the LC80 experience with this model and these are all part of the intended final product, after all!

RCRun Diffs & Driveline

The diff gears themselves are of the helical-cut type and the steel used in these parts does seem to be solid. I didn’t need to shim my diffs at either end, but this would be all you might need to do to ensure the diffs last as long as the truck. (If you’re unfamiliar with the process, I’ll have a video and article up on this at some point, but in short: shimming the diffs means basically using shims (really thin washers) to move the pinion gear closer to the crown gear for closest possible mesh. You want just a half millimeter between the pinion and crown gears – any less and you’ll be putting unnecessary wear on the teeth, and any more and you’ll eventually wear the teeth down until the diffs click and you lose drive. Shim diffs for close mesh and you’ll be all set!).

Overall the driveline on this vehicle is engineered to suit the intended purpose. The bad threads on the transmission housing were a slight hassle but with the price of this model in mind, the value is still definitely there.

Final Thoughts on the RUN-80

If you have some modelling experience and are ready to build a kit with a hard body, this is a solid choice. If you’re a Landcruiser fan, this model should especially appeal, as many other 80-series RC cars on the market appear to be copied from this model, in both 1:10 and smaller scales.

The value is good for what you get, especially for the thoughtful suspension arms and booted shocks. The main drawback is that you need to buy the body and interior separately, but bought all together it still is not a prohibitively expensive exercise.

RCRun Driving Experience

With the servo-driven steering wheel moving with the front wheels – especially if you place a little 1:9 scale figurine in the driver’s seat – your escape to realistic scale driving can be complete and engaging. (Update, there’s a bit more info here about installing that part of the kit).

Coupled with the sound from the rather loud transmission that has that big petrol engine sound when under load, the trail driving experience with this scaler is very good.

An additional enjoyable factor is the weight from the rather heavy body introduces a degree of body roll that gives further impression that you’re driving a proper four-wheel drive vehicle and that physics are very much actively working with and against the rig. It’s quite an enjoyable experience, all round.
