How to make my T3 go about 30-35mph?
It takes more than just a motor to go fast. You would need at least a 14t motor and a 2000 pack. You also need a speed control that can handle the current drain from the motor. If you don't have good quallity batteries and speedo your speed will only last a few runs. I have seen 10 turn motors run as slow as a silver can 540 because the battery was shot. Then they got a new battery and fried the speed control. Firt get a speed control that can handle down to around 12 turns. Then get a high capacity pack, then get the motor.
Trying to run a hot motor without a good battery is like trying to run an Indy car on 87 octane, it just doesn't work.
