was lookin at sme of the gearing posted on the previous page,. I went with 17/46 with a 1400kv on 6s. should be around 35mph. Does that sound right?

Also running the 46 or smaller spur you can omit the shim under the center diff if you run an elite rc motor mount. The elite rc mount raises the motor a lil higher than i would like for it to so leaving out the shim brings it back down a mm or so. JMO
