Greg,   
        I am working on a kr2 project. I brought it to University of Alabama
where the engineering guru's and their students are using it as a learning
tool.
        One of the things they are exploring is composite spars with
removable out board wing sections using the as5048/46. They will build wing
spar with wing attach to test. I will be glad to share the results.
        They also have decided to go with retractable gear. So I can offer
you / ( kr netters) the fixed gear, wheels...
        Question: I see there is a combined 48/45 wing template set has
anyone built a 48/46?   Does anyone have insight/suggestions on this
combination?

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.

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
