gearing...???????

hi guys, ive been a user but havent been on this forum for years. i recently got back into my electric rc cars and i got a problem cuz i cnt figure out the gearing to make my car faster. i have a xray t2 007 and my pinion gear was 32t and spur gear 71t and i clocked it at 67mph. i was told the bigger u go on the pinion(motor?) gear the faster ur speeds will be so i put in a 43t pinion gear and i clocked it at 59.... do i have this all backwards or something??? thanks.

The pinion gear goes on motor, the spur is the gear it drives. Using bigger pinions and/or smaller spurs will increase top speed,but reduce acceleration. Using smaller pinions and/or larger spurs will reduce top speed, but increase acceleration.
