KR> KR2 Top view Drawing Request
As per our phone call could I request a drawing of the top view looking down on to the ribs that make up the width of the aircraft? If you would like I can redraw them in a auto-cad (dwg or DXF) format if you would find that helpful. My contact information is Stan McDonald 402 Mudcat Road Foxboro, Ontario K0K2B0 (613) 968-9516 Thank you for taking the time to talk with me and may you have a safe and happy flight. Regards Stan

Received. Thank for the well wishes. I will check the plans when I get back this weekend.

That's GROSS weight of the plane, not empty weight! I'm sure we all know that, but somebody will call me out on it... -- Mark Langford ML at N56ML.com http://www.n56ml.com

Can I build the fuselage before making a final decision on whether or not I need my aircraft to meet the sport pilot operating limitations? This is not so complex a question, but the answers are! 1. Sure, it's simple to extend the wings and get to 51 mph, but if you want to retain exactly the same spar strength, you'd have to do some re-engineering of them. Personally, given that I've seen how strong these spars are, I'd do it without further concern for the spars, especially since you will have to keep the plane light as well (within reason...you could add a thousand pounds to the plane and 30' of wings and all bets would be off!). 2. No, almost the same answer as above...the extra Corvair weight can be compensated for by more wing area, and more spar re-design, but it would obviously be too fast for Light Sport then! I'd stick with the VW and be happy with it if I wanted to fly Light Sport, but that decision could be made later too. 3. Sure. There's a simple equation for stall speed that involves the lift coefficient of the airfoil, density of air, weight of the plane, and wing area. You can juggle all that stuff and figure out how much wing area you need based on your weight, and therefore the length and planform. If I were going to build an obviously KR-like airplane and make it meet Light Sport, I'd be prepared to show the FAA guy or DAR that equation to prove my point. Otherwise, a guy armed with the same equation and a tape measure could quash your dreams... -- Mark Langford ML at N56ML.com http://www.n56ml.com

Well Brett I would suggest to you that it stalls at 49 mph. I can assure you no one other than you will fly it to find out.

KR> KR Net Calling for a copy of plans and assembly manual for a 1986 version KR2
Hello KR Net, I've runout of ideas on how to get a reference set of plans for my KR2 - N44774. Built by Gary GArvin in 1986- switched hands 5 times- never flown!!! - new AWC. Will start Phase 1 testing in about 3 weeks. Has conventional gear. VW 1835 engine. Single stick. single 14.5 gal tank. Its sweet and I am pumped BUT your knowledge is Very Important to me. Will fly out of Spicewoods Airport just west of Austin Texas. Don't hesitate to contact me directly. L. Rene Ffrench 512-547-7164 Thanks lrffrench at gmail.com +1-512-547-7164
