As for fishing weights being cheaper, it depends, but they are a lousy shape, unless you are talking about "split shot" which are very expensive per each in comparison with buck shot. The only problem is that the buck shot has to be bought in 10 or 25 lb. bags. If the lead is scrounged from old buildings, flashing etc. and/or wheel weights from a tire shop it's literally dirt cheap; OTOH, pure lead wire from Corbin is $20.00 per 10 LB. spool, dia. from .125' to .440" in several sizes. Probably the easiest way to create a strip would be to cast one (or two) inside a long (6'?) piece of 1" ALUMINUM "U" channel. Dean: don't get me wrong, I still think it's a neat and elegant idea; BUT ... The aileron gap cutback per the KR-2 manual (page 88) is 1/2", which I work out to be 12 degrees. So the only space available is the thickness of the hinge material plus about 0.080" (2 deg.). However, as I see it, there is nothing preventing a new construction spar being angled at 15 or 20 degrees. The question is, would that be enough to allow for the necessary amount of weight? Probably a gap seal wouldn't hurt either. As for some general numbers, lead weighs 0.4097 lbs/cu.in., so 6' x 3/4" (the inside dims. of 1"x 1/8" "U" channel) x 1/4" would be 5.5 lbs., 3/8" would be 8.3 lbs., etc.; and 0.440" round lead wire would be approximately 4.3 lbs. per 6' strip.
