Well I have a Novak HV 6.5 in it now on 4s LiPo and I would say it does an easy 40 MpH with 19/87 gears, maybe 45. And with 1" of ground clearance I have no problem with control. I mean it doesn't flip over it just spins out repeatedly if I corner to hard. How much power would you actually get from that 1930/8 on 4s? The HV puts out 400W already. I got the motor information off of the
Fine Design page. Yep I said the "F" word.
