One other note/question about my setup: There doesn't seem to be a sweet spot with my power when I'm trying to hover. It's either not quite enough power to hold it or to much power and I'm climbing vertically. Is it characteristic of ESC's to have crappy resolution of power output or is it the Sky Hooks unit I'm using? I think the Jeti ESC I have on my Sunwheel using a Speed 400 does pretty much the same thing. I'm not sure since I hardly fly it anymore.
