I purchased the green B26 disregarding the reviews I have previously viewed about the props coming off during flight for no reason. This why I am buying these parts. I spent a lot of my hard earned money for this beauty. Don't get me wrong she's a looker. But what a bite in my ass. 3 flights in and she spot off the starboard prop, rolled over and destroyed herself. No explanation. I will.say I am going to try to rebuild her with these parts. So... next flight, new all around servos and threaded prop adapters. Those collet styles don't seem to clamp enough for the torque from the motors!
