No, a 33 teeth pinion can't be right - rather 23 teeth. When you use the standard 48 pitch 84 teeth spur gear you will need a 24 teeth pinion to reach 5,95, a 23 to reach 6,21... I would advise you not to gear the car too low for the beginning. Start with a 21t. pinion (84t. spur gear) to get a gear reduction of 6,80 - then slowly lower it up to 6,5/6,2 maximumely with a 19turn motor at such a race track. |
