All my work is based on the cramer truggy : https://cults3d.com/en/3d-model/game/cramer-truggy-rc-4x4-full-3d-printed
Ive fallen in love with the idea of a chassi made of TPU so i decided to keep at it with the idea, but i wanted to brushless full power drivetrain that only real Rc parts can deliver.
- Update on this, the front dogbone shaft needs to be shorter, im sourching and waiting for a proper one to arrive but it seems its around 85 mm
“This kit contains new housing for diffrentials front and back and a center diff using 2 90 mm dogbones.”
Bearings and cups from these using 100mm dogbones to give an allmetal drive train.
If there are interest i cant modify these files for traxxas parts but for now ive gone and sourced it pretty cheap from china.
ive also made some TPU cushions to take out the slack between the center diff and the dogbones. I currently have some issues with my current motor so my machine rides a bit choppy from start to fullspeed but this seems to work overall.
Its still in its beta stage for this.
Ive redesigned the upper arms to be able to be used with 100mm shocks still, this will however require me to once again redesign the body posts for the open RC chassi.
The center diffrential house model is very basic and unfinished in my eyes but works and fits.
However you need to superglue in nuts in the roof
All of this has been done as a hobby project during my sickleave after a carcrash(well the car crashed into me), i know its far from perfect but please comment and have opinions so we can make this an even better build.
My next idea around this is to buy a spare part set of example traxxas machine and fit it to this, i however would need some founding in order to achive this if it would be interesting.
I like this car as a whole and the project dukesdok made since i made one for my son and he can drive it and smash it into a wall without anything breaking.
I really believe that this can be a real cool platform to build from even more just like the open rc project
