I had a similar problem with my 6.00 X 6 Cleveland wheels that I got off of a C-150. The tires that came on the wheels were about 17" in diameter and way too big for a KR. When I checked with a major tire seller in "trade-a-plane", I was told they only come in one size. WRONG !! I found tires at "Wicks" that are only 13 1/4" in diameter. They are similar to the 6.00 X 6 X 15 that is used on the Cessna single engine retractables. Later, in replacing the tires on my Tripacer, I found the replacement tires to be nearly 1 1/2" larger in diameter then the tires being replaced. I'm sure this will hold true on the 5.00 X 5 tires also. Take your tape measure to the local airports. Most single engine Cessna's use 5.00 X 5 wheels on the nose gear and the early C-150's used them on the mains also. Check the different brands for diameter. Also, I think a lot of RV's use 5.00 X 5 on the mains. Measure them. Check with different suppliers and see what diameter tires they have. The tires you need are out there, you just have to find them. Changing the lower bracket might be the easiest way to get the wing clearance you need. If you are making your own gear legs and haven't got them cut yet, make them longer. Mine are 29 1/2" long. Remember, you will need clearance to take the wheel covers on and off unless you change the design on them also. Good luck!

If you can find a picture of the Altimizer and compare it with the Quicksilver on Edelbrock's Website you will see they are identical in appearance and function. Able sells the Altimizer for $380, the Edelbrock 36mm retails for $200. I had a friend who runs a motorcycle salvage yard order me one for the wholesale price. Even with an overnight charge it only came to $168. The tech guy at Edelbrock said the carb flows about 312 CFM. The carb is altitude compensating to 10K feet. It has a slosh plate to keep the fuel near the pickup in the float bowl. So any high banked turns on a motorcycle or in a plane will not be a problem.

There's nothing magic about the horizontal stabilizer airfoil drawings, or the length of the horizontal stabilizer, with relation to the AS5046 or 48 airfoil. I just throw those in because it's what I used and it is a "real airfoil". If you already have your spars glued in place you can just use the RR "airfoil", and add on to the tips with foam and several layers of carbon fiber like Troy did. Or you can just laminate some more spruce on top of the existing spars to build them up high enough, using scraps from the main or aft spar tapering operation. You could even build up the top and bottom with spruce laminations, extending them the extra few inches on each side, fill the middle with foam, and wrap it with fiberglass. Now THAT would be an ABORTION! Hmmm, come to think of it, that sounds kinda like the hoaky foam spar on the wing tip! I guess what I'm saying is that just because you're using the new airfoil doesn't mean you're "forced' to use that horizontal stabilizer airfoil, but the extra stabilizer length would be nice to have. Maybe the real answer to your question is that carefully selected aircraft grade Douglas Fir is a sufficient substitute, if you don't mind ripping the old spar out and replacing it.

Christensen" Subject: Fw: KR> Substitute for wood Message-ID: <001501c07ffd$20dd4780$7a785ad1@davec> Vince, Here are a couple of quotes from my Mirage Marathon builders manual: "Use only aircraft grade wood which can be purchased from Wicks Aircraft Supply or Aircraft Spruce and Specialty Company. Unless you know the specifications for aircraft grade wood and can apply them, do not use any other wood for building your airplane. Since the wood carries the structural loads, you do not want to compromise the strength of your airplane." "Other materials such as Douglas fir and Port Orford cedar are acceptable, as long as they meet the specifications for aircraft construction found in Advisory Circular AC 43.13-1, "Acceptable Methods, Techniques and Practices: Aircraft Inspection and Repair", available from the Superintendant of Documents, Government Printing Office, Washington, D.C. 20402. But unless you are an advanced woodworker with experience in judging materials according to the specifications, you are better off to order from a reputable aircraft supply house." Also these other woods are heavier than spruce and especially on a KR any unnecessary compromise in weight is unacceptable to me.

Unless you know the > specifications for aircraft grade wood and can apply them... On the matter of replacing this horizontal stabilizer spar, what we're talking about is going from 2" deep (by the plans) at the root to almost 3" deep, and from .625" deep (by the plans) at the tip to almost 1.5". See http://home.hiwaay.net/~langford/kmlht5.jpg . That's a lot of margin he's building in, and I'd guess that aircraft grade Doug Fir can take up the slack here. Having said that, I'd just order 2 more 7 foot spruce spars if I were going to replace them, but that's just the way I am. But another consideration is that shipping gets pretty high the longer the pieces get. Although I don't pretend to have done any flutter analysis on this thing, stiffening things up (such as by making the spars taller) generally reduces the opportunity for flutter to begin. I might add that nobody has specifically tested this horizontal stabilizer for flutter, but Jim Hill has been flying this exact tail with no problems so far. As always, I should mention that any changes you make to your plane from the plans are at your own risk. And of course, TET only provides these horizontal stabilizer templates in case your independent engineering analysis proves that you can use them...

Frank Ross came out from San-Antonio TX to visit me and N541RY this last weekend. Seems he thought it would be more fun to help me work on the KR than to wait around at the hotel! I'm glad he did, he offered to help out, which took a bit as I had to think about how to take advantage of the help I decided this would be a good time to do the preliminary fuel flow tests. I grabbed the fire extinguisher, and some gasoline, and we proceeded to pump fuel from one place to another for sevaral hours. There were several points which had I been working by myself, I would have said that's it for the day, but with Franks help, we pushed through all the rough spots and we was able to measure the fuel flow at a nearly level attitude from all three fuel tanks. Left Wing Tank -> 1 Gal/4 minutes Right Wing Tank -> 1 Gal/4 minutes Header Tank (Gravity) -> 1Gal 5 minutes I fed fuel from a 5 gal "approved container" via a rubber hose to my fuel connections at the wing stub. This was a preliminary test to find leaks, and get a benchmark on the flow rates forsubsequent fuel flow tests. It would have taken a lot more time to attach/remove the wings for this day of testing. There was initially some air getting into the fuel from some loose fittings, but this was identified via trial and error. I still have some seepage from some of the fittings at the 3/8" fuel selector and around the fittings for the header tank, but generally the situation is MUCH improved over my last fuel flow tests. For the simulated climb attitude tests, I think I will use a ladder, and time the fuel flow to a gallon container which is elevated (top of the ladder), but for gravity flow, I will have to come up with some type of jig to get the plane into a climb attitude, or just specify no center fuel on takeoff in my POH. (Although I'm pretty sure it would be OK). Since we had so much fun Saturday, we had to go out flying on Sunday, (in a rented Piper Warrior)... I think my third landing was pretty good. Both Frank & I took photographs, so maybe someday I will post one on the 'net. -- Ross ------------------------------ Date: Thu, 11 Jan 2001 22:21:21 -0700 To: Brian Vasseur From: Ross Youngblood CC: krnet@mailinglists.org Subject: Re: KR> VW Priming (Procedures/Installation) Message-ID: <3A5E9451.E3BD224B@teleport.com> Brian, I like both ideas.

This means I need to get cracking this weekend to get a cable long enough to reach from my PC to where the scanner ended up when I moved things around in the office a few months ago. I have the Compu-Fire system which replaces the distributor cap, and rotor so you don't need any wires going to the distributor except those provided by Compu-Fire. Just provide a good ground (bolt to the firewall), and hook up 12V. The tricky part is hooking up the tachometer... don't ground the black wire, or you shut off one of the two coils. Trust me on this. -- Ross "Livingstone, Danny (DJ)" wrote: > Hello netters > > I am relatively clueless when it comes to installing magnetos or electronic > ignition system.

After glassing the vertical stab, I cut and removed a piece that wraps around the top of the elevator so I can get easy access to the top of the control horn and the pully. This was a real pain to do, and has lengthened my build time. The first acces cover and layup of the turtle deck was done in Kevlar, and is VERY hard to cut and surface without using a lot of micro.... I finaly made a new cover with glass and it is much nicer. At any rate, there should be a couple of photos of the cover OFF at http://www.teleport.com/~rossy/N541RY.htm I don't have any new photos of the cover at this time. -- Ross Jim Morehead wrote: > Netters, > I have read about cutting a round inspection hole in the plywood below the > Horizontal Stabilizer to have access to the lower elevator cable.
