Thank you, roll overs are not on my agenda
Seriously, if it rolls over, it will shatter. That`s for sure. And it will get worse after each repair ...
So, no roll overs with this body.

Thank you, that`s the plan.


For today, I cherry-picked an unnecessary but nice gadget. I started on the front power take-off shaft. I had the outer parts laying around, so I let go.

I plan on using a mini gearbox motor on the inside as power unit, but I haven`t decided yet which size and speed. Painting for the rusty look on the outer parts will follow later.

You could use that to power a winch.

Yes, a mechanical winch is a good idea. I thought of an auger or a sevage pump.
Maybe an electric power generator, that would be fun. Transforming electric energy into kinetic energy and back into electric energy

Thank you, I am happy if you find some inspiration. I would like to see a pic of yours, of course


Small updates tonight. Update number one, I painted the Tamiya shock housings (gun metal grey):

Size:  138.8 KB

Made some shafts from stainless screws:

Bolted them together with two red rubber rings (working as rubber springs)

Size:  122.4 KB

Now I have some nice looking tensioners (still waiting for the rubber bushings)
As I have a very slow moving rig, I do not need much tension on my tracks, so this will work fine for me. You speedy guys will need a more dynamic solution for your tensioner.

Small update number two, I had to install the mandatory yellow plastic safety cover on my PTO
So I got some plastic drill boxes and cut them up

Put some paint on them

I finished the fuel cell today. I managed to build a flange for the fuel lines. I used some styrene sheet for the flange and made some bolt heads from toothpicks:

1,5mm welding rod for a guard:

Fuel cell with flange, filler pipe and breather. The original Unitrac has an even more ridiculous filler pipe but no breather and flange on top, but I wanted to give it a more interesting look:

To mimic the screw joint I used som 2mm styrene rod and drilled it out with a 1mm drill bit. Oh man, once the scale bug bites you, you are lost

I am running out of excuses now for not painting the body ...

Man that is really coming along. I love the amount of detail! Do you plan on playing with it once it's done or is it going to be a shelf queen?

Thank you!
Of course it will get some runtime! But to be honest, I have the most of fun building it and then test drive it to see if it works as it is supposed to. If not, or if something can be improved, it goes back to the workbench.

It will get probably the most runtime by the kids

Finally I started with painting the cab. First I had to mask the windows from both sides, as I will paint the cab from the outside as well as from the inside. This is necessary because I will use a dull color, which isn`t a lexan paint, therefor I have to use a lexan paint for primer first. And since I want to see the same color on the inside as on the outside (as common on Mogs), I have to paint from both sides. I hope this makes sense and I hope it will work.

Masking is done:

I got interrupted by the postman, who brought some very nice scale parts from rc4x4-shop.cz for the UT90:

Man, you are going all-out with the detail on this thing. I'm content to use the stock body covers or panels that come with my vehicles, I just care if the mechanical and electronic parts work as well as possible. Looks like a great project for cold winter nights, though, as long as you have someone to keep you company when you get sick of tinkering.

Yes, once you get into detail, you are lost

Same with me, my main interest is more in a technical manner. But after seeing all these nice scale trucks in this forum I had to give it a try. And even as a beginner it`s a lot of fun for me doing all the details.

Don`t worry, no major marital problems here. Just a fun winter project filling up some free time

Any video showing the rig in action? I'm curious how fast it is compared to stock with the motor/ESC combo you chose. Also curious about the low speed control with the sensorless system.

Low speed control is still miserable and high speed, well, uhm, not that high at all. Anyway, it is a slow, bumpy ride, just like the real one
But now that I have the matching programming card, I will get back into this and try to teach him some manners
I am currently using the radios V-Tal mixxer, which is limiting my choice of channels, so both throttle and steering are on the right hand stick of the radio at the moment
I will order a seperate V-Tail mixxer to have the full range of channels available. I still prefer to have throttle on the left and steering on the right hand side ...
