Default RC8T E pinions and spurs...

Those of you running the RC8T conversion what are you using for gearing? I have the RC8T, AE conversion kit with the two spurs 46t and 50t, MMM V3 2200kv combo, 4s 5000 25c, and soon will have the 5s 25c 5000 batts. What pinion and what spur should I run?

use this site: http://scriptasylum.com/rc_speed/_top_speed.html

Gear to have a top speed of about 35 - 40 mph for racing to start with.

Right now I gear 54/17 using 4S and the castle 2200Kv motor for 39mph, assuming holeshot LPR tires.

for you equivalent would be:

50T & 4S ~ 16T pinion
46T & 4S ~ 15T or 16T pinion

50T & 5S ~ 13T pinion
46T & 5S ~ 12T Pinion

I created this speed and gearing calculator in Excel. It has a list of common ring & pinion ratios and available spur gears.
