RE: New Tamiya Hummer On The Way!! Need Help Making It OffRoad Capable
For the motor, I'd try one of the trinity stockers, Ive got the monster horsepower stock in my TLT and it has more than enough torque.
If you do end up getting one of the tamiya motors, get it off ebay. I seen them all the time for like $23.
For the diffs, you can usually just fill them up with epoxy, jb weld, etc. to lock them. You can even screw them together if you prefer.
For the shocks, you better wate untill it come sin so you can measure the stock ones.
I dont know what youll do about the body, the stock is one is hard plastic so I wouldnt suggest using it unless your car is gona stay on all 4's at all times, otherwise it will get beat up pretty fast. Proline makes a military style hummer body for the T-maxx, and HPI makes a jeep body for the savage/T-maxx. But I think theyd be too large.
