The pics of his built are gone. But this is what he wrote about his truck.
Motor: lehner 2230/16 with a Reisenauer Gear reduction 6:1
Controller: Schulze 40/160
Batts: 24 x GP 3700 Nimhs
Geared for 34 mph. 24 minutes driving per charge. very low temps of every component.
He made a custom mount for it to be belt driven. That's all i remember.
But i guess a belt would't hold up the power aqwut is lookin for.
