So is the 2820 12 a better choice for the plane? And that can be paired with the 11x5.5 prop. What about battery mah and c rating.Yes, that will work very well. The battery can be a 2200 mAh 4 cell with a 25C rating. We do not need higher than 25C for stunt and the higher C ratings just weigh more. The next popular size battery is the 2700 mAh, and if you don't mind paying a lot more, then the Thunder Power 2700 is great. It weighs the same as some of the regular 2200 packs.
