my gearing is 18/47. it is geared pretty low in first gear. when it hits 2nd gear, it gains a bunch of speed. if you do use a feigao xl, i recommend the 10xl on 6s lipo. it will run cool compared to the 8xl or 9xl and it will draw very little amps. i think the 10xl will only pull about 63amps max. if i were you, i'd get the feigao 10xl or 11xl (58amp max) and 2 3s 3000mah 20c lipos from hobbycity. the batteries only cost $25 each. or, you could get just 1 6s 3000mah 3s 20c pack. for that setup, you would only need the 70 amp supersimple esc.

for the feigao motors, leave it 2 speed and use a 14-16tooth pinion with a 47tooth spur.
