From reading the net for a year it is my understanding that there are many KRs flying and yet no spar or WAF failures to date. A KR flier has removed his WAFs, inspected the wood spar attachment area and WAFs for hole size, pitting, and surface rust. The only "problem" is surface rust and stain on the wood. THIS IS GOOD INFORMATION and gives a solid data point for all of us. This wing has a well designed spar and WAF attachment design. As you customize the KR to meet your personal needs consider not changing the basic primary structure and not needlessly adding weight. Weight is the enemy of any really good aircraft. While engineering production line repaires for F-4 and F-15 acft structure for McDonnell Acft never once did I design a repair of a non- defective area or to increase the repair strength greater then that designed into the aircraft. But all my major and minor repairs ensured minimal acft weight increase, minimum impact on aerodynamics, and installability of the repair. Having the Stress and Aero Dept at my beck and call made my job easy, and they designed two really fine aircraft.. The KR design is also a really fine aircraft, and affordable. bob morrissey cam...@earthlink.net >
