Update. I have quite a number of flights on this HK450 gt pro2 helicopter It has never had a hard landing or been or crash but
I have found that the main shaft has become slightly bent inducing the above wobble. Do they bend with time or flight stress?
Strange. I've bent quite a few in the past but never had one bent on it's own. I will now call my heli HK URI Geller MK1 GT pro 2
Cheers
