Hi,

it is hard to compare since you have different motor, but with my 500kv HXT50-55b I got 47A with fresh batteri pack, so approx. 1000 W. Best is of course to measure the amp, but if you don't have anything to measure with, check in other forums, I know that your motor is used a lot in Hyperion YAK54, so lot of info in those theards.

Regards
