Awesome stuff,you dont see many planes/pilots that do inverted harriers that low. I want one right now!! Did you put a DA50 in it? If so,what throttle setting does it hang on,I've heard some say the DA50 will prop hang a 16# plane at near idle,a little unsettling for a new engine. Anyhoo,I'm thinking of a Velox when the Do goes and the AW Extra as my next projects.
