Originally this plane takes a 11.1v 1300mAh 20C Lipo, but we put in a stick pack Lipo 11.1v 2200mAh 25C battery in to this plane turning it very nose heavy but the bird flew just awesome. It could do more aerobatics, was a bit faster and handled better. Landings are tricky though lol. Next thing gonna try a two blade prop on this one.
