I like this little thing. I have flown quite a bit more and it kept like a champ crashed possible. I give it four stars because, no matter how much I try, I can not put it right trim, somehow, to change while the propeller, and that is the direction of the engine, now the air is forced to rise switch, rather than decrease as it is now replaced by four-blade fan axis plane. Soon I'll update when I figure out how their original direction reverse back there.
