SK3 Comp. F3A, Popeller 19 x 12. The TURNIGY K-Force 120A-HV OPTO, and 2 x 5S Zippy 4000 Compact 25C, measured 65 Amps and 2250 watts. The Rotomax makes a good impression.

20 flights without any drama. I think a 19x12 is the largest prop you can expect to run on it/mine draws 78 amps on one.

So far the best product I've bought from HK, it's very well made.
