KR>Wing attachment brackets
Netters, I made my own WAF's from l/8th inch 4130 steel that I ordered from Acft Spruce. I cut out the pieces on a table saw using a carbide blade and made all of the holes on a drill press. If the cutting and drilling is done slow and the part being cut or drilled is dipped in water often so that it does not get hot the metal will not change, that is to say it will not become soft nor will it become hard and brittle. My KR2 with the WAF's I made flew for almost three hundred hours before it was sold and there never was a failure in that area.

KR>Registration
Max, Thanks very much for the legal advice. I am sure it will be of value to some of the builders. If you still have an interest in building and flying your own aircraft I can tell you from my experience the KR aircraft are the easiest to build. They are also very durable and strong. Properly built they will provide a safe and very enjoyable flying machine for years. Years ago out in California I was at Meadowlark airport with Ken and a lawyer friend of his was about to fly his KR-1. This was long before the KR-2 was designed. When that lawyer landed he told Ken that the last time he flew an airplane as hot as the KR-1, it had guns on it. This guy was a former P-51 pilot during WWll. Ken's KR-1 had a turbocharged Revemaster 2100 installed and would in level flight get up to 200 MPH.

KR>Building a KR-2
Dan, Build a KR-2S rather than a KR-2. The KR-2S is an improvement over the KR-2 and much more stable in flight.

KR>Registration
Netters, I am not a lawyer so may not know what I am talking about so I wish some of the members of the net who are lawyer's would respond to this message with their expertise. It seems to me since every KR aircraft I have ever heard of, including the two (KR-1 & KR-2) that I and a partner built back in the 70's has been much modified from the original or the present day plans. Like I think the plans call for the RAF 48 wing and several builders are using a different wing. KR aircraft have been extended in length, made wider, have different canopy configurations, landing gear and the list goes on. If there is any change in the building process that does not match the plans then it is not a KR Aircraft but your own design using the KR plans as a building guide. Since it's not a KR aircraft, why should Rand Robinson have anything to do or say about it?? Bob Stone, Harker Heights, TX rsto...@hot.rr.com
KR>group building
Oswaldo, It not only can work but is an excellent way for a group of builders to get their projects done. The by products are encouragement from each other, profit from each others errors during the building process and not make the same error. More heads to figure out a difficult problem and best of all camaraderie. You may even be able to get lower prices for items needed by group or fleet purchase. I see only positive things and nothing negative. Good luck to all of you. Bob Stone, Harker Heights, Texas, USA rsto...@hot.rr.com - Original Message - From: "Oswaldo P.

KR>Pin holes
Netters, I don't understand all the talk about pin holes being such a problem. When I built the KR-1 and KR-2 years ago (l977) after laying up fiberglass and resin we covered the entire surface with a piece of cordite sprayed with mold release. This is kind of like cling wrap only thicker. When it was dry and the cling wrap removed the surface was so smooth that very little sanding was required. After minimal sanding a coat of feather fill was applied and sanded. Feather fill sands out very easy to a surface smooth as a shirt button. There were a few pin holes of course but there was also a product like bondo that came in a tube like tooth paste. each pin hole got a finger dab of this paste and then final sanding ready for sealer and paint. The finish was so good on our KR-2, we won the best composite prize at the Chino Airport EAA Fly-in in 1977. One of the judges told me that their final decision was biased on the beautiful finish. There are much better products on the market today than Feather fill and bondo so I just don't see pin holes being that big a problem. Bob Stone, Harker Heights, TX rsto...@hot.rr.com
KR>Boat fiberglass or plywood skins
Netters, It's been a long time since I built and I do not have a set of plans any more but I seem to remember the original design was for the boat frame to be skinned with 1/8" aircraft plywood and then covered with a thin layer of fiberglass cloth and Ken thought this would make the strongest structure considering all the compression and tinsel pressures from the engine. As long as I knew him (from 1970 to his death) he never had an engine fall off so he must have been right. Bob Stone, Harker Heights, TX rsto...@hot.rr.com

KR>RE: 2 strokes
Netters' What Ace says makes a lot of sense to me and the makers of kit helicopters must think so too because so many of them recommend the use of a high HP outboard. I have never agreed that any engine designed for surface vehicles is all that safe in an aircraft but for those who just cannot afford to use an aircraft engine like continental, or Lycoming an out board motor would be the best alternative.
