Another that should be added is to make sure that the when the plane is sitting still. Look at the nose gear leg and make sure that it has an angle of about 3 degrees when looking at the gear leg from the side, or 90 degrees to the center line of the fuselage. Meaning that the bottom of the gear leg should be in front of the gear leg where it ends the angle and striaghtens out heading down towards the ground. I forget what the name is, camber or something. This is standard on the Grumman AA1, Tri Q200 etc. Greg Martin ----- Original Message ----- From: "Orma" To: "KRnet" Sent: Monday, September 19, 2005 2:44 PM Subject: KR> Shimmy > Bob there are several other reasons for a nose wheel the shimmy.

This means that if I use a straight push rod all the way back it will sit near my hip, and we all know we do not have much to spare there either. So a series of push rods is needed to get it low between the spars and then back up the elevator horn. I am planning to model up my own design in the next few weeks and will gladly share it for scrutiny with the net group. Have you done any load testing with the bent (joggled) rod in compression? I would be concerned about it bending under maximum input load and suggest if you have not done some testing you should, pin the down stream bell crank and see what your Pull up and miss the mountain force is and is it deforms the bent push rod or not. I just be saw something that looked a little skinny on the column bucking side, it may be perfectly fine, but for every one that is looking at push rod designs, even your straight push rod designs should be analyzed and proven by test to be safe.

I was rather excited when I first saw them being used and in some areas they have had reasonable success, like the gyrocopter in Australia. I've never seen any real success in the KR in my 16 years at the Gatherings and years on the net. I've only seen one fly and it was a heavy KR to start and I wasn't too impressed. The engine will be heavy, cooling problems, and lots of little engineering things you'll probably have to work out on your own. Long story short, If you can't go with say an 0-200, I'd go the Corvair route and build it conservative. Go the 110hp route, don't bump the compression too much, short prop extention, etc. Dump the engines to whoever wants them. Again, just my opinion. No experience with Sube's or Vairs although I have three Vair engines waiting in the wings. Glad you enjoyed the Gathering and hope you took some good info home with you.

What is 'non standard'? In my case they're the hand turck type and come in three different grades. None of them are verry good, but the split wheel rim, tube & tire are. In my nose wheel I'm using a 3/4" tube as the axel so the double tapered bearing has to be able to fit that. I'm checking into what's available here locally for the double tapered roller bearings. I may have to make an adaptor to mount the races into the hub but not sure yet. I've got plenty of room outside of the wheel itslef for the bearings to mount. I would have to shorten the spacers though. -Joe Message: 8 Date: Thu, 22 Sep 2005 07:02:04 -0500 From: "Steve Bray" Subject: Re: KR> KR landing gear To: krnet@mylist.net Message-ID: Content-Type: text/plain; format=flowed Joe & Bob The bearings in my nose wheel are rough when installed.

To: krnet@mylist.net Message-ID: <209.9ffa11d.306498d0@aol.com> Content-Type: text/plain; charset="US-ASCII" For those interested in the SUB installations two names come to mind. Steve Makish and Bob Lester are the only two that I know who have SUCCESSFULLY flewn many hours behind Subaru engines in a KR2. They know all the problems and had all the bugs worked out. Since then they have removed the Subarus and installed Corvair engines. I believe Steve has 150 hours or better on his now and I have 290 hours on mine. WHY the change? To move from a more expensive, complicted engine that can wear out in 500 hrs to a much simpler engine that is easier to maintain and costs less to build. Now all the installation packaging is worked out and available and there are corvair engine running that have over 1200 hours on them and never been down for major maintenance. I like the Corvair personally and will continue to fly behind it.

This is a bearing distrubitor that I've never been to that didn't have 3 to 5 grades, prices, of any size. I think the od was standard but the id was odd for the od. I didn't push it because I don't like the set-up. It has a 3/16 bolt running through the axle. It's a Dehli (sp) set-up and I take it that this works but I want more between my prop and the ground. I'm a ways from useing it but when the time comes think I will make another axle in a common size, 3/4, and put a 3/8 bolt through it. To put cone bearings in means they would need a nut on each end to keep the pre-load right. Ball bearings should work fine if they are good ones. As I say I'm a ways off and still thinking of going back to a tailwheel but was wondering if other people were using this set-up, that 3/16 bolt scares me.
