Where should I gear my Orion 13.5?..rubber on carpet. I think I melted one this weekend trying the "4" FDR thing. Tried 4.2, 4.6 and ended up at 5.19 with a motor of 165 F. Seemed really slow. Any help would really be appreciated.
Cool 416 thing: rubber tires with a 96 spur, your pinion = rollout. Example, 38 pinion = 38.12mm rollout, 39 pinion = 39.13mm rollout...really easy to remember.
