I'm looking to find out if there are any known structural problems or things to look out for with the Hangar 9 Ultimate 46%. I bought a used one and went through it very well and fixed a few problems that the original ARF builder had not done correctly.

For example, I know that with the 1/3 scale GP Pitts, there are known issues where the firewall will tear off since it needs better bracing and there is another issue where the upper wing will tear off in flight (I saw it happen!) because the aluminum bracers fatigue and snap while flying. I didn't know if there were any notes anyone had about the Hangar 9 Ultimate?

Thanks
David
