It cost me 11.00 per linear yard @43 in wide. A great deal on some surplus. It is 282 carbon comercial grade. It weighs 5.8 oz per yard. That is almost the same as the weight of KR glass I think. It uses the same amount of resin as glass and generally woking with it is the same as glass. You can vacuum bag, I guess. I just laid it up like regular glass. I did a test to see if I would gain, or lose weight. If you are very carefull with your resin the two types of consturction are identical in weight. The only weight savings I had was the foam frame. I don't know how to explain it well, but the weight savings I ended up with was this: If you made a fuselage out of 5/8 foam instead of spruce and weighed it, then subtracted all the extra resin that I put in my layups that I didn't have to, then you would have a small weight savings. I'm sure that made no sense whatsoever. The weight of the kr2, not the "s" model, but the kr2, with center spars and fittings was 64 lbs per plans. My plane was 24" longer, 6" wider, and 2" taller, it also has laminated and bent spars that are bigger and weigh more. Last weight ck I did showed that I would be at 80 lb.
