And a Free drivetrain does not really mean a whole lot....just make sure that nothing is binding up...like no locked up bearings and over tightened screws that will bind the drive train up. It doesnt matter if the car free wheels for 40 seconds or 10 seconds.....once there is a motor placed on the drive train and the car is on the ground all that goes out the window. Main thing is to make sure nothing is bound up....dont get too concered with how long the car will free spin for....thats way over rated.....leave that for the TC3 guys to lose sleep over.
