Reply:Nice video. im just glad to see the guy went to school and learned to weld. As a welder and EAA member it frustrates the hell out of me when i see so many hideously welded fuselages.www.performancealuminumfabrication.com

Reply:hard to test for fatigue, as it usually results from the airframe or wings flexing, no matter how little, but can have catastrophic results.
