I'm not racing in the vintage series, so am not the best person to ask but I believe that a control motor was sorted out by Stu and bought from Pete at Castle models. Best bet would be to have a word with the boys tomorow, However, you can always run the car in the normal heats (these are sealed can 540 style 2WD, modified 2WD or modified 4WD) in which case use whatever motor you feel most comfortable with is always the best
