The Continental engined KRs seem to have a slightly different look than most KRs; Larry's looks similar to Jeff Scott's in many ways. Look at the top photo at http://www.flysquirrel.net/KR/JeffsKR.html Also notice how low Jeff's canopy looks. Many folks on this list have gotten rides in Jeff's KR and can probably offer more in the way of real-world commentary on headroom based on their experience riding in a KR that appears to have an exceptionally low and sleek canopy/turtledeck line.

I think I have a 6" pneumatic now if I can iron out some details like finding a bearing with 1/2" I.D. and=20 7/8" O.D. and 1/4" thick.

My favorite shot of Jeff's plane is at http://home.hiwaay.net/~langford/jeff_wallpaper.jpg . It's my Windows "wallpaper" background. There are many more at http://home.hiwaay.net/~langford/redoak2002/ . I've flown in his plane, and I didn't have enough room to pull my camera up to my eye to take a picture, although some of that was that the sling seat was jacked up for his son's viewing pleasure. But I think Jeff would be the first to tell you that it's too low, and if he had to do it again, it'd be a little taller. If you have to err one way or the other, make it too tall, rather than too short...

Look at the top photo at >http://www.flysquirrel.net/KR/JeffsKR.html >Oscar Zuniga ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ The reason they look so similar is that they ARE so similar. Jeff's KR is longer then standard and I believe a bit longer even than the 2s. I don't recall if his is lengthened 24 inches as mine is. Jeff and I have, to my knowledge, the only two sets of Diehl 30 inch gear legs. His main gear wheels are 500X5, mine are 600X6. We each started with an 0-200 cowl from Dan Diehl and then added additional length to fit our engine setups and I removed the bottom center section on mine and rebuilt it to fit the standard 0-200 carb layout. Jeff chose to go with a single piece, forward tilting canopy and I believe it is a Dragonfly or 2s design. I felt I wanted some additional roll-over protection so I installed a fixed windshield / gullwing door setup. I built my windshield and turtledeck bows from plywood scrap end stock I got from Wick's for $2 a bundle. My windshield is a portion of a broken Pulsar canopy I got for FREE and I had enough left to do the rear windows. The glass in the gullwing door and right side panel are from a standard KR half bubble. The gullwing door opens up 60 percent of the top and the right side panel is easily removed for maintenance as well as serving as an emergency exit. My turtledeck started life as a premolded KR2 assembly that I lengthened, widened, and reshaped to match the turtledeck bow. The radius from side to top was taken from the lid of a 32 gallon trash can. My door latch was made using the 3/32" rod that was used to align the elevator and rudder hinges. Lengths of rod had washers welded to one end at the latch handle and run through and latch in to nylon blocks made from a cutting board I got from the Dollar General store. The latch handle is made from 4130 tubing using the same geometry as the latch on the glass door on my pickup truck topper. I also "borrowed" one of the gas springs from the glass door as it was exactly the right length and pressure. This is probably more info than anyone wanted so I'll shut it down here. I will have construction pictures of all this at the Gathering if anyone is interested. JUST THREE WEEKS TO RED OAK !!!!!

Some of you may find them interesting. I'll keep the Net posted on any developments. Larry Flesner +++++++++++++++++++++++++++++++++++++++++++++++++++++ (to Matco) I have a T6 tailwheel assembly installed on my modified KR2. I have been searching for a 6" pneumatic wheel/tire to replace the solid wheel you supply with the T6 assembly. I believe I have located the wheel assy but I'm having trouble finding a bearing to fit the 1/2" axle. I'm needing a bearing that is 1/2" I.D. and a 7/8" O.D. If I'm unable to locate such a bearing I'm considering the possibility of having my 1/2" axle machined down to a 7/16" diameter. My question is as follows; how was the 1/2" axle in the T6 installed? I'm assuming it is a press fit. Can I remove the axle without damaging the assembly and if so, how would you suggest I do so? I would have the 1/2" axle (bolt) cut down only in the exposed portion and leave the portion that seats in the assembly at it's present size for re-installation. I'm assuming that I could re-threat a portion of the outer threads to 7/16 also. A short tapper in the area of the diameter change would hopefully elminate a stress point. Any suggestions? Thanks for your help. Larry Flesner Carterville, Illinois +++++++++++++++++++++++++++++++++++++++++++++++++++ Mr. Flesner, The axle is not pressed fit into the casting but only preloaded by use of a sleeve inside the bearing. What wheel are you considering using on the axle? Does it not have a bearing in it now or is the bearing a 7/16? If is a ball bearing? I assume you mean a 6 inch OD tire. How much tire load will the tail wheel see? We have had requests from customers for a pneumatic version of the T-6. I have located a supplier for wheel, tire, and tube but the wheel is steel and the bearing is not sufficient for a/c use. The thought is to make our own AL wheel to fit the tire but I haven't been able to find source for just the tire & tube. A photo of the wheel you describe would be appreciated. Why do you desire the pneumatic tire? The inquiries we've had have been for ride comfort. George R. Happ MATCO mfg +++++++++++++++++++++++++++++++++++++++++++++++++++ George, Thanks for your quick reply. I'm on my way out of the house at the moment but will try to get back to you this evening with info on the questions you had. My cost on the wheel was $21.50 from a local supplier. If you would like I could purchase and ship you one. That included the bearings of 7/16" I.D. which is my present problem. I'll try to get a digital photo of the tire when I receive it also. Some testing at your location may prove it to be an answer to your search also. The supplier gave me a used wheel/tire/tube that they call an 8" tire (mounted on same wheel) that measures (tire) 7 1/2" in diameter outside. I'm not exactly sure what the 6" tire they have ordered for me will turn out to be. I hope to have my project flying soon and it could be used to test the application. I'll keep you posted.
