Im sure I've seen that truck somewhere before....

Anyway, i think the problem is you have enough power bolted to that truck to move a 1:5 scale... nay, 1:2 scale even (powerwheels jeep). I would suggest running a single plett- more than enough power.

You would need to get a custom machined output shaft for the stock 3906 tranny design, or go to a centerdiff type setup perhaps...
