The Lancair 320/360 and the Pulsar XP have all composite construction, fuel in the wings and removable wings. The Lancair wing spars are attached with only two bolts for both wings at the two common attachment points inside the fuselage.
Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA smw...@md.metrocast.net -------------------------------------------------------------------------------------- Hi Dave Many thanks the reply. I am well familiar with the KR2 Super and its website, have been studying it since February of this year as well as many other KR builders sites. I like the KR2Super very much and building with composites is no problem for me - been doing for about ten years for model RC planes ( a different story but composites are not new to me). As usual one sets out with a plan and a list of desires which normally are not fulfilled in every way by existing designs - in other words one tends to like different things about different designs but never finds the "ultimate solution". So I want a two seat, side by side and homebuilt from plans. It would be great if it could fit into LSA limits (again a wishful thought). That led me to KR and the KR2S. Further research led me to alternative materials due to wood availability in my country. I found the KR Super and got excited. Trouble for me though is I want the original wing design with WAF's, fixed undercarriage, fuel tanks in the stub wings and I want to put it onto a trailer to take home in winter and save storage cost for fuel! Scott's KR2 Super does not allow for this with his spar design. I also like the way Mark has rebuilt his wings - from the fotos it is a far simpler construction the the Supers but he used "beefed up" woodens spars. I also find nothing difficult/complicated about the Supers spar design - website has excellent instructions, very good foto's and if followed correctly and taking care with the layups and methods an easy part to make. I am by no means a designer and would be lying if I said I understood half the technical discussion on spar design so was hoping to compare what I have found out and worked with to someone else who may be more familiar with the design aspects of a spar. So back to my original question/query - has anyone designed alternative composite wing spars using the original WAF's mountings design idea? thanks again Greg ------------------------------
