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

Brokes very quickly. The problem are the magnets inside the shaft: thei broken like glass and they are not properly fixed.

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.
