KR> Glassing Tiger Gear legs
FWIW, I bought the last set of undrilled gear leg blanks off eBay this afternoon. When I called Fletchair, the guy said that someone just bought all he had, except those. That being said, he still had several used sets available. -- Sent from Gmail Mobile

Dan, Did you leave your leg thickness ( 1") the same, or did you cut then down to a thinner size. How are they performing?

Dan; I believe the legs are actually for a Cougar, the Grumman twin. Gross on a Cougar will be quite a bit higher than for the AA-5, and your plan should work well. Peter

I've dealt with these guys before and found them to be decent people. I bought the O-320 for my SuperCub there. They gave me two used Grumman Cheetah exhausts that I was able to modify to use as the exhaust on my SuperCub. Very reasonably priced and good people to deal with. It appears that these are old inventory that is in need of recertification to sell for use on a certificated aircraft. But it should be some pretty good stuff for use on a KR. And the price is right. I was looking at one of the KRs at the gathering that had the cut down Grumman gear legs on it and was somewhat surprised at the stiffness of the gear as compared to my 30" Diehl legs. I think I would be tempted to plain it down a bit more. -- The Ebay Ad: US $19.50 - New undrilled Grumman Tiger, Cheetah, or Traveler laminated fiberglass landing gear leg 1?

I did not thin them out. I dialed in the flex I thought would work by reducing the width. I read of an earlier KR2 which the builder simply cut the leg down the middle. He said they worked just fine. His KR was a 900 # plane. From that point I knew my plane was going towards the 1250 # GW range. Applied some simple math and there you go. The flex and deflection seam right. If I find them to be to stiff I'll cut the down. If it's not stiff enough I'll use the other set of legs I bought and start again. At that price you can experiment some.

I think when Dan Diehl tested the KR2 unidirectional glass legs that he manufactured or cut from from Scotchply he found that due to the offset in angle forward and outwards that there was a tendency for the legs to twist slightly as they flexed on landing. The glass 45 degree wrapping was intended to reduce that torsional influence. However, I don't know how significant either the twist or the wrapping to address it proved to be. Nor do I have any knowledge of how the Gruman legs would act although because they are thicker it is possibly even less of an issue. Scotchply has since been taken over by others (Cyply??) and is hideously expensive.

I purchased the blanks for the AA5 series main gear fiberglass struts for $17.50 each plus shipping from Fletchair Parts - Call 800 FA-WINGS (329-4647) The parts that I made are on my KR-2 now and appear to working ok. The ready-to-bolt-on parts cost $245.00 each for the Tiger. The blanks are 1-inch thick; you will need to plane these down to 3/4-inch, cut to shape and size, and find some bolt holes. A power wood planer and a power metal band saw works well for the first two operations. I will not bore you with the details how to go about it. However, just one inquiry on this forum will get the details flowing to bore the rest of the 600 or so netters who really don't care about that.

I thought it was because the Scotchply was unidirectional and it was to prevent the legs from splitting through the bolt holes.

Phil, these legs were not wrapped when install on the Grumman. They had a fairing for aerodynamics but not structural. That's how I did mine.
