Ahhh, so this would explain why I got better aileron response on the last plane i built (Furious 3D) whenever I used the 2S vs. 3S battery. I thought it was doing better because there was less air being pushed over the wing surface with the 2S but i guess that had nothing to do with it?

BTW Chellie, i just replaced that monster ST .10 motor and 35A ESC with this setup from Head's Up RC: 2408-21-B Brushless Motor & 18 Amp ESC
Do you think it's ok to use a Orange 10x4.7SF prop with a 2S 1350mAh 20C batt on this setup?
