I have gotten in a few flights with my Harrier 46 and I am a little disappointed. I have a Saito 72 on it and have it balanced at the 140mm mark. It just does not seem like some of the other 3D planes I have had. It seems to come in fast and won't slow down. I have a 13x4 prop on it. I don't know what it is, it just seems squirrelly. When I go into a hover it acts like it is falling out nose heavy. I tried making it tail heavy but that did nothing. Any thoughts?
