Are you sure you have the same motor? I am well over 800 watts on mine with an 8x8. Mega 22/30/3. Mine is direct drive. Are you using a gearbox maybe?

Strange, I put a 10x7x3 MA Prop on mine and it's drawing about 420 watts at 30 amps.
I haven't measured it but I believe I'm getting about 58+ oz of thrust as the plane which weights 3lb's 6oz easily lifts itself and accelerates when pointed straight up.
