Today I maiden a Phoenix Models Extra 300S that I built for a friend. I am using a Thunder Tiger Pro 46 that is about 3 years old and well broken in, although not unlimited vertical this engine pulled the plane at a good pace. The plane hand no nasty habits what so ever. I yanked the elevator really hard several times to try to make this thing snap and nothing. Also on landing it had no nasty habits of tip stalling. This extra for the money was not a bad deal.
Check it out.
