The Nobler is a very good airplane. Is is amazing to think it was designed to fly the much less demanding Old Time Stunt pattern of 51-52. I have judged a fair number of TopFlite ARF Noblers and they can be made to fly very well. There are a ton of posts on how to modify them to make them better. I have never built a Nobler, but I had the pleasure of watching George Aldrich both build one from scratch and fly it. In fact it was the first stunt pattern I had ever seen flown, and I though no way can I learn to do that. Well, now I can at a middling Advanced level. So do not despair
