My first attempt to build a mini-scale truck trial, features drive and steering. Including building instructions.
Mechanics is very simple. A M motor drives worm gear on 24t for propulsion (with 12/12t bevel gear for steering). Steering is operated by a M motor with worm gear on 8t and rack pinion. All suspensions are pendular (width axis for front and length axis for rear). Clearing abilities are very good for this scale
