    AS with other V spec motors I have tried the KV is way, out the only one that is close to the stated KV is the 540-L 810KV; This motor seems to be around 1600KV. I tested it with a Graupner CAM 5.5x5.5 speed prop on a fully charged 2450mAh 4S lipo. Current draw was 30A Volts 15.0 RPM 22,680 efficiency of this motor is very good just above 80pcnt

    Very powerful motor, my 2,6 m e- glider weight 1,6 kg is a rocket! Climbs almost vertical, use 10-6 folding prop, aluminium spinner, 2,2 Turnigy 3 cell lipo and 40 amp Hobby King blue ESC. 15 - 20 sec to almost "out of sight" altitude.!

    Superb product for the price.



    With a 10"x6" folding prop (HK), it pulls just a fraction under 30 amps at WOT from a 2200mAh 2S pack, for a total of ~220 watts.



    Bare wires, no connectors, but it's no big deal to solder some 3.5mm bullets.
