I've been lurking for some time now. Joined just to answer this.

I have the Elite as well, mine has the O.S. 55 with an 11x6 prop. Fantastic flyer, I did have to crank those bolts down quite a bit. I sometimes develop a small amount of play after a few hours of flying. I just retighten as necessary.

I love this airplane and it is a fantastic flyer. Inverted flight is great along with basic aerobatics. I increased the throw a little all around and it really helped. I also have flaps installed and that really slows this plane down. Without them, she likes to come in hot.
