Hawksky AT1107 8500kv
A large 11xx class motor from Hawksky
Broad power to easily handle medium and light loads. Peak efficiency is a little on the low side, but it holds up over a fairly large region, so you won't notice much of a change in efficiency between light or medium loadings. Efficiency also seems to drop off very quickly at lower throttle positions, quickly falling to under 50% efficiency for the bottom 1/2 of the throttle range, so to get the best out of this motor it wants to be run only near the high end of the throttle range.
