I second the 3DHobbyShop Extra shp. I'm selling all of my profiles and glo engines. From now on I'll only have gas and electric. This little plane flies just like my 88" ExtremeFlight yak w/Brillelli 60. No kidding! Somehow, it even flies better than my profiles in the wind. Harriers with no rocking. It does everything (harriers, rolling harriers, hovers, flat spins, blenders, knife edge) better and easier than any 40 size 3d plane I've ever flown. It's an amazing plane.
