Alright back on track for the CPP for a bit....One thing I found that helps the stock back tail motor, is going to a carbon fiber tail rotor blade. They weigh 1 gram less than the stock plastic ones, and believe me for that little motor that's big...Lol.. I've never broken one, and have them on both of my CPP's. There pretty tough ! I've had my fair share of crashes and I'am pleased with the durability of em'.....
