Cheap Easy T Copter For FPV
This can be flown on 3 cell packs but with allot of gear 4 cell is a better choice. I use zippy compact 2200 and 2700 25C 4 cell packs from hobbyking. When in stock I get the 30amp F30A ESC's and flash them to SimonK software. its not necessary to do this but it makes things more precise and snappy.
