I have a reflection/rimfire/bl8 esc/ and 640 3cell lithium. the recommend 9x3.8 prop will not hove the plane. The 10/3.5 that comes with the brushed motor will hover at 1/2 throttle. I don't have a amp meter, but will this prop pull to many amps on this set up??? What is the proper prop?

PS My plane is a few ounces heavy......i was very generous with the glue
