I am new to 3d. I have a Blade (EPP - similar to a shock flyer) with a nippy black 0808 - JETI 8amp esc - 2 cell poly 720mah - 10,4.7 prop. My first 10 or so flights ended up in nose dives and I may have damaged the motor. The bottom line is that it barely hovers. Does anyone know if this setup is adequate for 1/2 throttle hovering? If so, could a damaged motor still produce enough power to hover? Maybe it is just under powered or something else.

PS At slow speeds the motor sometimes squeeks but the shaft does not look bent.

Thanks,
Idiot Newby
