Greg,

You thinking maybe the voltage is a little too much for the ESC? I never considered that, just figured 80 Amps through a 77 Amp ESC was the problem... Now that I think about it, the Jeti 77 is only rated to 30 cells, and by my count, a 10S LiPoly is the equivalent of 34 cells. (3S + 3S + 2S + 2S = 10 + 10 + 7 + 7 = 34 cells) You might be able to get away with 9S, but not 10S.

That's a real bummer, because these big outrunners have some real promise in 50cc gasser applications. I mean, your 1/3 scale Edge is meant for an 80cc gasser, isn't it? On a 15lb 25%-29% ship, it should easily give 3D performance without pushing the motor nearly as hard.

I don't know where they are on it, but Castle Creations was supposedly going to come out with a Phoenix ESC rated for more than 30 cells last time I asked Shawn Palmer about one. Modelmotors is also supposed to be coming out with a TMM8032, 80 Amps, 32 cells.
