KR> gap between wings
Hi Surely the answer is to remove the rear WAF bolts and only leave the bottom main spar bolt in place, when removing the wing. This would prevent any unnecessary stresses. This string interests me as I am doing the wing roots as we speak. My added complication is that I am using a version of Ken Atkinson's pushrod controls which has the pushrod and bellcranks in the gap. So I have inset the foam rib on the outboard wings 2" outwards to give clearance. then I have tapered the top foam from the join back to the rib and am glassing the inside to give the overhang strength. (a bit like Larry's) Access to the top main WAF bolts remains a problem. I am thinking of cutting access holes and floxing in ally shelves with anchor nuts attached and fitting a 1/16" ally sheet flush inspection plate with countersunk screws for neatness. I can then put a similar, bigger inspection plate on the underneath.

I think the plans are silent on removal all together. I use two cheap adjustable office swivel seats (backs removed) on castors under the wing to support it using the height adjustment to reflect the dihedral. Then I remove all four bolts, fuel lines etc and just wheel the wing out. Simple and the seats are used for beer drinking outside the hangar at other times.

I cut and glued an additional 48" rib to the inboard end of the outer wing spars and used that extra rib and the outer 36" rib as my sanding templets to shape the outer wing. With the stub wing completed and the outer wing completed, that left the gap between the outer wing and the stub wing to fill. I filled the gap with foam, sanded , and glassed. I then cut the wings apart, enlarging the cut in the ares of the wing attach fittings and separated the two. I sanded the underside of this foam to form a triangle shape and glassed that. That gives me a gap, with wings installed, the thickness of a hacksaw blade with cutouts in the area of the wing attach fittings. I tried making glass covers for the gap but when the first set did not meet the quality I was looking for I went to the hardware store and bought a roll of aluminum "flashing", 6"s wide, cut it in half, and attached to the wing with a few screws. That has worked for 355 hours now and I doubt if I'll ever change it. I do have a roll of white flashing material that I may get around to installing some day. http://mysite.verizon.net/flesner/02092585.jpg http://mysite.verizon.net/flesner/020925113.jpg http://mysite.verizon.net/flesner/lf103.jpg I later found it necessary to cut a 4" X 9" access hole in the bottom of the stub wing between the forward and aft spar to attach fuel lines, electrical lines, and have access to calibrate my fuel senders.

I have a different opinion on this. Give yourself plenty of room, maybe an inch or so, and even more, from spar to spar end at the attach points, extending enough fore and aft for getting your fingers in there to attach the wings. Then make some good gap covers like the ones you can see at: http://krbuilder.org/WingGapCovers/index.html And I just noticed that the method for attaching was not included, which I will document next month when I remove them for annual. They attach with 2 screws and a couple of springs. The reason for this radical opinion, is that I tried my best to get them real close on my first KR, and ended up buggering them up before it was all done. Just too much work for very little reward, if any.

Daniel R. Heath - Lexington, SC -Original Message- can I put all the gap filling foam on the wing ? Which is the easier way. I do plan on using the wrap to seal it when all is said and done.

I'd put all of the foam on the stub wing (that wasn't a choice, was it?) and glass it into the stub wing skin. If you put all the foam on root of the wing side, when you lean them up against the wall your foam and glass will get smooshed (tech term there). And I'd make them meet together perfectly so that all that was needed to fill the gap would be 3/4" white electrical tape. That's an "upgrade" I'd like to do to mine next time the wings come off (that's been a few years already). I had the same question when I did mine, but didn't have the good sense to ask that question when I was building mine... Mark Langford N56ML "at" hiwaay.net website at http://www.N56ML.com

Hey Guys, I've got a little question. I will be glassing the stub wings this weekend and I was wondering if the area between the stub and the wing template gets the same amount of foam to fill in the gap or can I put all the gap filling foam on the wing ? Which is the easier way. I do plan on using the wrap to seal it when all is said and done. Mike Sylvester kr2s builder Birmingham,AL. Cell no.205-966-3854 _ Windows 7: Simplify your PC.
