Ok guys I have a bit of a problem. I just test ran the car in ths street out front. The 4.5r is tooooooooooooooo powerful, I think. My tires make a weird noise at full. The car has a diff in front and rear and it torque steered like really bad, uncontrolable. what can I do? I am running a 25t pinion and 128t spur. Using 4200 NiMh. I love this car. It was flying down my road faster then my Kyosho V1RRR with TZ12. This car is bad to the bone I might have to go to the 10.5r motor but I love speed and this fills the need if I can control it.
