About a year after ordering, my Thunderbolt rolled into the hangar on Friday. Great excitement followed by a whole Saturday of my wife and I muscling that beast into the 4 engine mounts. Hi temps and hi humidity - lots of cursing - but got it hung! For some reason I just don't remember the IO-540 being so difficult but that was ten years ago! ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
