I picked up a used roller and I am converting it to a mid weight 4 gear. I want to compare a heavier 4 gear truck to my ultra lite. Both will have 4 gear trannys, cDiffs, M2C toe blocks and comparable motors (Tekin Pro4 4000kv and a Castle 3800kv).

My 2nd truck coming together.

Same mods as my 1st truck, servo flat on the chassis.

Second 4 gear modded motor plate and cDiff.
