Thanks for the info, now here is the big Q. Whats it weigh? The FireFly comes in at 14 grams W/gearbox. Its going into a 3.6 oz. foamie. I'm looking at the Micro Joule flight pack currently as it will offer the weight savings that I'm looking for. I think the ESC, RX and two servos are under an ounce. Thats basically the type gear I'm looking for. The lightest standard gear wreaked havoc on the wing loading. I tried 370 Park on a D box, naros, Pheonix 10 and a 3 cell/720 mAh LiPo. Sure it hauled it around, but it flew like crap. I need to lose weight, and so does the plane. Joe
