While I was assembling my Mini 4WD 1/32 Unimog, I came up with the idea of making it remote-controlled and, of course, steerable. After doing some research on the Internet, I had the impression that my plan was not entirely unrealistic. I wanted to at least try it. It soon became clear to me that I didn't want to modify the chassis, but wanted to keep it in its original state. I had to build a new chassis myself. I couldn't keep the existing nice worm gear and central drive shaft either, as it would no longer be 4WD but 2WD. So I had to think about a new gear unit and for the front I needed a new suspension and, above all, steering. To be honest, I was pretty apprehensive about the whole thing. But one day I got to work... Here are a few photos documenting the creation of my 2WD RC Mini Unimog. Maybe it will be an inspiration for others who are planning something similar. Most of the parts I already had at home. For my project I bought a set of wheels from a Mini 4WD Land Cruiser, a bag of gears and a small 2S Lipo. After initial tests with cardboard, I made a chassis out of 5mm walnut wood. Now it was time to think about the front suspension and steering. Unfortunately all my replacement steering knuckles were too big. So I made my own, one set out of plastic and one out of wood. I chose the wooden ones. A one-piece steering rod. Two seperate steering rods are better. :-) First steering test with servo connected - it works! Now it was time to install the axles, the gears, the servo and motor in their final (and exact) positions. I had to measure very, very precisely. It took me a while to get the chassis tuned well enough. That was the moment when I really gained a lot of respect for the work of the engineers and designers in car construction. If I had installed nice 1/32 TRF oil dampers, it would have been easier. :-) And now I could finally start installing the electronics. It's been already very tight with the motor and servo, but now the controller, receiver and LiPo still had to be accommodated. What a crowded house! And of course I needed body posts! Comparison of the original and homemade chassis. And then came the big moment: My RC Mini 2WD Unimog drives. It actually drives! The gears are'nt running smoothly yet, the steering angle is too small, that could be improved. In particular, the gear ratio is not right yet, I would like it to be more like a crawler. But for now I am happy and will leave it as it is. I now know how to do it and can build a version 2 one day when I feel like doing these tiny tinkering things again.

Nine months ago I bought this little rarity: Mercedes Benz Unimog, 1/32 Mini 4WD Series No.9 — small and fine! Since the early models of this Mini 4WD Series are so rare, I'm going to create a build thread. The box is small and light, as are its contents. 🙂 The instructions are very clear, in other words very minimalist. I am going to paint it grey (TS32) to match my 1/10 Unimog.

Tamiya "Tracked Vehicle Chassis Kit" & Carrera "1957 Chevrolet Bel Air Custom"

I have built quite a few of these Tamiya mini 4wd racers. When I saw this new starter pack from tamiya I couldn't wait to get my hands on it ! This kit is fantastic value for money considering what you get in the box. On the side of the box we can see all the extra's (Tune Ups) you get Inside the box this is what you get. (note you even get a little screwdriver as well as the usual spanner) so on to the build - oh but first I added these to my build. building ..... note I ball raced the spur gear too. Gears in, axles in and the ballraces the motor ready to go in the chassis motor in chassis wheels on and the carbon parts laid out ready carbon parts on rolllers and mass dampers on the underneath all complete body on - I have had this one ages and put it on the car, note the stickers are different to what's on the box but it is the same style of body. I really enjoy building these little Tamiya mini 4wd racers, just a shame there is no where to race them. (what this space )
