2-speed motors
 

2 Speed Motors.....Think about that...... SHIFTING!My god! Anyway about that. When you hit the shift button does it act like a Nos booster? Also the auto modellista kit is a 2 speeder, it comes with a 2.2 motor will the car still shift if you use a better motor than 2.2? thats about all just wanna find out. Thanks

2 speed cars are slow as dirt unitl you hit that boost button....other motors do work

The 2-speeds are in the chassis, and not the motor. There is a thread about this a few weeks ago about this. Do a search and you should find it.
