I purchased 2 Eagle 50s from x-heli.com and both of the original motors failed within 2 days of each other. I purchased another motor from them and one from e-flight blade cp and took the stickers off and put a heat sink on them and they seem to be ok.one of my helis had a 9 tooth gear and the other one had a 10 tooth.will Exceed replace my burnt up ones? Maybe Andy can tell me.
