Message-ID: Hi, I read Zeke Smith's book this weekend, which I had ordered from www.amazon.co.uk (why don't they have Bingilis? I know it's at www.amazon.com, though). He says that a certain Bob Martin of EAA chapter 338 , San Jose CA, found a better method to work with dry micro. As I understood, working with dry micro is a real challenge. To keep it light, it needs to be dry, and that makes the substance hard to work with. This requires more than one session of filling and sanding. Zeke says that mixing the substance with alcohol makes it more liquid, so it really applies very fast, while the alcohol evaporates, leaving the dry micro light and dry, which was the goal. He also mentions the possibility to use water to extend the time. Can anybody confirm this?

Phone 507-289-2436 and his internet address is pietenpoldon@juno.com . The plans call for the hub to be fabricated from cast aluminum and there have been no reported failures with his design. It includes the safety shaft and nut, the front plate, and machining instructions for the crankshaft. The motormount plans consist of one Corvair to Pietenpole mount and one Continental C-65 to Pietenpole mount. Vie Kaplin a friend of Don's can fabricate the Hub to the plans at a very reasonable price and I recommend his workmanship. Talk to Don for Vie's address. Vie likes to do the hubs during the winter so now would be a good time to place your order. ------------------------------ Date: Mon, 9 Oct 2000 18:58:33 -0500 To: , From: "JEAN VERON" Subject: Re: KR> Oldest Flying KRs Message-ID: <000b01c0324c$d67d19c0$8d111b3f@computer> N4DD recieved it airworthieness sign off on 7-12-76 and first flight was 7-13-76.

Well, the fog still hasn't cleared, but I DID get Mark Jones' video in the mail, and took notes at the end. Here are the results: Marty Roberts won "oldest pilot", "best engine", "best KR2", and the "spot landing" which we didn't really have, but we figured since he landed on just about every spot on the runway, he was a shoe-in. Jim Faughn won "people's choice", "best interior" and "best KR". It was "nip and tuck", but Steve Bennett won "best KR 1", but then his was the only one there, and his is really a KR 1.5. Also, Bill Kirkland won "farthest flown" for arriving from "halfway to the North Pole" in his Cessna 150, for the SECOND year in a row! Marty needed to up his gross weight just to carry all those plaques home! Thanks for the video, Mark. Job well Done. Marty's in about half the shots, mostly orbiting sideways at high speed, or just as background "music"...

I have not heard of a single incident of structural failure on a KR, even though most are flying heavier than the design weight. ANY airplane flown heavier than design gross will have less of a G rating than it does at design gross. I wouldn't even consider taking off in a Cessna or Piper if it were overloaded the same percentage as some of the KR's that are being flown!! Whatever the weight, you have to keep the CG in range. Beyond that, know what the extra weight does to performance and structor rating and fly accordingly.

Marty Roberts is using Dan Diehl's original wings, built back in 1983 (or thereabouts) on his plane. You saw what he was doing at the Gathering with two aboard, and probably a gross weight of over 1200 pounds. He actually has a G-meter in his plane. I wonder what the highest number is that he's registered...

Yes the wing is strong +/- 7 g's at 900 gross and general aviation requires 4.5 g's for utility category. During a stage of my KR construction when the wing structure was covered I inverted the airframe and supported the structure on the canopy longeron. I put 4000 lbs of driveway gravel in plastic grocery bags and weighed each bag.(20 lbs approximately) then stacked the bags on the bottom surface of the wing and fuselage with progressively less weight to the wing tip. (thats alot of weight I distinchly remember commenting. And the fully cantilever load had "virtually no deflection". My recollection of hearing wood creaking sound from the centersection region caused me to stop loading at 4000 lbs. (not to push the test to ultimate load but just enough to verify the integrity of the workmanship). So I'm satisfied with 4 g's if I'm grossed at 1000 lbs. A 60 degree bank is 2 g's and gust loads in level flight in strong turbulance can exceed 4 g's but I don't ever want to fly in that rough of air. The KR I built gave me peace of mind by the static test I made to safely comply to the utility category. The horizontal stabilizer attachment concerned me for negative g's and I added a fillet on the underneath root to enhance the shear load distribution to the longeron rather than tensile loading the spar to longeron bond. __________________________________________________ Do You Yahoo!?

It was to be fitted with >Revmaster 2100 engines Hmmm... kind of like what you see at http://www.geocities.com/taildrags/KR/Tango01.JPG except 4-place? And as far as the ability to use the "Rand method" to design/build just about anything, yes-! The "construction trainer" I'm building is exactly that. It uses the same wood frame/foam infill/glass over method as pioneered by Ken Rand, and so I'm learning the techniques to be used on the KR. Actually, I've been thinking about the simple lines of a Britten-Norman BN-2A "Islander" twin, using the "Rand method" of composite construction. Scale it down a bit, make it 4-place, hang a couple of Corvairs out on the wings...

Tom Bagnetto's outstanding KR1 is caught on "film" quite at bit at the Perry Gathering site at http://home.hiwaay.net/~langford/k97gathr.html . It's Type 4 VW powered, and really screams!

Subject: Dynel vs. Fiberglass again Message-ID: <39E362E8.EB73B179@wanadoo.fr> I have just received my copy of 'Composite Construction for Homebuilt Aircraft' by Jack Lambie. What did I read there?!: p.140: 'Dynel is fun and easy. It clings like the plastic you use to wrap sandwiches with, or cover left overs. It has a big open weave and can go around all kinds of curves, including two directional, without wrinkling. The open weave takes a lot of resin so the parts may be heavier than for a fiberglass surface. Thus, fiberglass can be stronger for its weight because of the tighter weave and less of requirement for resin to fill it...' p. 182: 'Dynel Fabric - Dynel fabric as originally used in a 4 oz./sq.yd. weave in the KR designs is no longer in production...' Does it mean the 5.85 oz./sq.yd. fiberglass is may-be 'too strong' for a KR?
