I'm running a 17.5 v16 in 1/12 stock blinky. The track is 60x60 old gray carpet. I've been experimenting with the motor but not getting the results. Which rotor should be used? I have the 1750 plus the standard and what timing should I be using? The motor typically comes off at 130 area on an 85 rollout with 40deg of timing. Any thoughts or suggestions?
