The KR100 was built by Kevin Kelly, who was doing some work for RR at the time. He did several interesting things with it, among them hinging the flaps and ailerons directly from the aft spar, and giving them more "normal" proportions. I was told that he provided plans for the design to RR, but that it was never marketed for some unknown reason (even HE didn't understand why). He built it with the intention of racing it, and didn't do too bad, from what I remember. I think it had an 0-200 or similar engine. It's still a one-of-a-kind airplane. I think he now works for Boeing in Seattle, but I could be wrong. There were several blurbs in a few of the newsletters, but that's about all the info ever published on it, to the best of my knowledge..

Has anyone ever thought of using the centre section of the clutchplate? I've seen a gearbox here with this type of installation and it works great....or is this old toffee?!! One nice feature of my reduction is that the drive shaft and the driven shaft are actually 2mm apart, so if the gearbox does fail the gears can be removed and a short 30mm coupling installed to join the two shafts together for a direct drive system as they both have the same splines. This will only be a temporary solution because of the vibration problem. One can make it permanent though if some type of dampening devise is installed... i.e a clutchplate ...How's that for D.R.P... ( drastic recovery plan).

Has anyone >ever thought of using the centre section of the clutchplate? Steve Bennett's rear drive uses a rubber coupling between the flywheel and shaft. I think I heard that Ross Aero may use something similar to a clutch disc center section, but that's just hearsay. The problem with the spring type center section is that it is just that, a spring, and doesn't offer any damping like the rubber does. It's there to absorb shocks and reduce chatter in the automotive application. It's possible that at the right frequency, the springs could reach their resonant frequency and self destruct. I've been tempted to try it myself, though. I've been trying to convince myself that with a careful enough analysis (involving crankshaft/rods/flywheel/shaft system) I can nail down the resonant frequencies close enough to tailor the system such that they can be avoided at operating speeds. The rubber coupling eliminates these worries, but puts 8 pounds way out front where you don't want it. Decisions, decisions... I got your picture of your KR and will post it. But you sent it to KRNet (like this one) so everybody else has it already too. Very nice looking plane.

Is Mark or anyone else who has given this issue some design thought seen what I am talking about. The whole set-up is very light weight and the concept could be easily adapted for aircraft use. Considering the abuse I subject my bike to, I would think it has fairly well proven it's durability. Those rubber biscuits absorb a tremendous amount of torque and are still in perfect condition after 23 years.

Maybe you could explain in more detail what it is you plan to do? It sounds to me like you want to remove the main spar and all of the wing foam and glass forward of the rear spar. I don't see any reason you shouldn't be able to do this as long as your new skin (fiberglass) laps onto the rear spar by a couple of inches. -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims Ailerons almost done! http://www.geocities.com/CapeCanaveral/Hangar/4136/ Aliso Viejo CA Give Blood, Play Hockey! ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---------------------------------------------------------------------- Subject: Re: vertical stab.

You would be much better off removing all the foam and glass forward of the vertical spar and making a new nose section using KR2S templates. Mount the new nose piece in such a way that the fin is straight ahead or close to it.

They are easy to insert, easy to use, and reasonably priced. Different lengths are available for differing thickness of cowl materials. The only drawback, was when the aircraft reached flight hours of about 3000 hours and more. The fastners, because of their small bearing diameter, tended to wear the holes in an elongated pattern. I was able to repair this, (and think it would make a much better origonal installation) by using stainless dimpled (flush) washers on the surface of the cowl. (PS, when we sold the flight school, one of the 150's had just over 10000 hours, and the cowl repair was holding up fine) Good Luck, Bill Zorc 73101.157@compuserve.com ---------------------------------------------------------------------- Subject: Re: KR100 From: Mike Mims Date: Thu, 20 May 1999 19:17:13 -0700 X-Message-Number: 20 "Blandford, Carlton C" wrote: > > > By the way, did you and Mike receive the photo of my KR?
