With an equal amount of time and effort you could install a lighter,safer, and faster fixed gear, either a self designed or off the shelf setup. Just my humble opinion. Larry Flesner
KR> Stock Retracts
As I continue to research the stock retracts on the KR, I've learned some things from looking at how Glenda Mcelwee designed her retracts (even though eventually she went with the Diehl gear). I like her locking mechanism ideas. I keep hearing about how hard landings can overload and possibly bend the landing gear. I think that a rubber bumper attached to the main spar can be used to absorb the shock and limit the upward travel of the landing gear spring ends on a hard landing. Also a 1' x16" or so length of additional 7075 could be used at the landing gear ends to stiffen it. I can see where camber and toe in could be put in as needed with proper shimming. Just some ideas. -- Glenn Martin, KR2 N1333A, Biloxi, MS
KR> Re: KR-2 Spars
Bill Clapp had formed a company to produce an all fiberglass version of the KR-2. He had exhibited the fuselage at AirVenture two years ago. Don't know if he got any orders. We made a bet as to who would get their creation flying first: Bill or me. I could not find Bill at AirVenture 2011. Have not heard from Bill lately, so don't know who is winning the bet. Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA smw...@md.metrocast.net - Greg, I'm building a KR Super2 which is an all composite derivative of the KR2S. The main spar has a core of 1/2 inch last-a-foam sandwiched with multiple layers of fiberglass and has spar caps of carbon-fiber rod. The construction is complicated and goes very slowly. It is strong but only 1 inch thick so replacing the wood KR2S box structure wouldn't be easy and mounting the landing gear would also require much work. So, I believe you'd be much better off building the spar per KR2 plans. If you like to learn more about building the KR Super2 go to www.krsuper2.com Dave McCauley -- Subject: KR> KR2 spars Has anyone designed composite spars to replace the wooden style spars used in the KR series? Maintaining the same design idea, outboard spars connecting to main spar with the WAF's, but using the modern composite materials. ___
