Need help with 1st BL setup in Emaxx!!

ok gotcha.

I was using the calculator, and gearing of 18/51 (mod1) would give me a top speed of 36mph... this is fine with me, but will this gearing produce wheelies on command?

Im kinda looking for a good mix of top speed and torque.

Maybe 15/51 would be a better choice (30.8mph), for medium sized open areas for bashing, and small tracks?

ALso, does the stobe slipper kit come with a 51t spur? it doesnt say so Im guessing I will have to get one. IS this my only choice?
