[MOC] RC Baja 1000 truck

[Danifill]

Hi! This time I decided to experiment with suspension once again. The goal was to make a simple model with a high travel suspension for off-road driving with some decent speed. So, it has two electric functions: driving (2 L motors) and steering (Servo). It has working suspension on all wheels: front independent with a positive castor and a rear live axle suspension. I used regular yellow 6.5L shock absorbers and they work pretty good, I'm happy with the suspension travel! Anyway, it could be a little bit smoother if it was heavier, but the weight had to be low. Firstly, I tried to use a buggy motor for driving, but it was constantly cutting off, so I decided to put 2 L motors directly to the wheels. Surprisingly for me, it works much better! It also has a detailed interior. The body part is not that pretty to me in some places, I'm not really good in building simple exteriors yet. :D I hope that you will like it!

Thank you!

Nice truck man! My only thing is I'm surprised the BuWizz with an RC motor doesn't work, I just finished a very similar build with BuWizz + RC and the power never cuts out.

Thanks! That’s probably because of the weight of the model, also the BuWizz I own is pretty old already, so it might not be at its full potential as well. It went well on a regular road surface with buggy motor, but the off-road was tough for it! L motors aren’t that “hungry”, so it was a nice choice for me. :)

Makes sense, yeah. I like how you put the L motors directly in the rear axle, replacing a differential. Minimal power loss
