After my most recent toyota hilux trial buggy build, I wanted to build a simple trial truck that was very strong. My goals were:
No gear "grind" in steering or drivetrain
Powered by XL motor and steered by M
Normal battery box (non-lipo)
No special parts so that many people can build
The strongest (in my opinion) suspension type is ball-joint with reinforcing link. So I used my ball joint suspension idea with internal gear reduction from last year:
Total gear reduction is 3:25 on 1x PFS XL. It has very good suspension and climbing capabilities, as well as meeting all my goals of no gear grind in steering or drive. Video:
