I did one the other day (number two so far) and carefully measured everything that went into it by the gram. The skin I did was the inside of the passenger side outboard wing, the part between the spars. It gave me a nice large area over which to average any errors. The total area to be covered was [(21.5 + 12.5)/2] x 79.5 = 1351.5 square inches. After the fabric was cut, it weighed 7.5 oz. I used 174 grams of epoxy to wet it out, and 160 grams of epoxy and micro to fill the foam before applying the glass. Bottom line is that the skin (without foam) weighed 19 ounces. My foam skin will be .375 inches thick, which will weigh 9.4 ounces, for a total skin weight of 28.4 ounces. I also added about 6 ounces of tape, micro, and epoxy to fasten the skin to the spars and end ribs around the perimeter. Grand total (not counting outer skin, which has yet to be applied) is 34.4 ounces. If I had built the skins using the method the plans call for, the three foam ribs would have weighed 6.4 ounces. The foam for this size skin weighs 1.57 pounds per inch of thickness, so assuming that after sanding you'd end up with an average of .6" thickness all over, that's 15 ounces. There's a little epoxy and micro required to glue the foam to the ribs, so let's say 4 ounces. That adds up to 25.4 ounces for a plans built skin (without the outer skin). Bottom line is that each double walled skin will cost you 9 ounces, for a total of 36 ounces (2.25 pounds) for the whole plane. What you get in return is a skin that is at many times stiffer and stronger, all over. Using the plans method, the more flexible foam deflects out of the way when sanding the airfoil contour. With my inner skin the foam is supported from below by the inner skin while I sand the airfoil contour into the outside. Lambie's "Composite Construction for Homebuilt Aircraft" states that by putting a core that is 10 times thicker than the glass between two layers of glass yields a surface that is 37 times stiffer, 10 times stronger, and 6% heavier than just the laminate alone. That's about what I've seen with my decks and stub wings so far. I'm sure you've all played with one sided foam and compared it to double walled foam. Plus, the entire wing will be torsionally stiffer due to the extra layer of glass inside. Besides all of this good news, I think it's pretty easy to make the skins this way. It takes maybe an hour to cut out and build the little sanding jig, and half an hour to sand out the insides. 1 hour to glass the inside skin, and (in the case of the lower skins) another hour fastening it in and making it removable (for access to the inside of the top skin). It's a trade that I can live with. And I'd be willing to bet that finishing time will be reduced due to the more accurate airfoil contour. Many of you will think life is too short for this sort of stuff. Maybe this kind of anal retentive behavior is why I now have 1750 hours into this thing, and suspect that I'm barely 60% finished. I'm now designing a new aileron and flap hinge system. When I get it figured out, I'll let you know. So far, it looks to weigh about the same, but all joints are in double shear. The surfaces themselves will have far less drag due to the lack of a top opening (in the case of the split flap) and the lack of the large gap at the bottom of the stock aileron (I'm using a Frise). I'll let you know how it works...

I had an interesting experience with a Mikuni on a motorcycle this weekend. At the garage where I'm rebuilding my 750 Norton Commando, a guy came by with an almost identical Norton, but with a single Mikuni (non-CV) carb rather than the twin Amal Concentrics of a stock Norton. His plugs were fouling from extreme richness at low speed, apparently like Dan's engine above. I'd never worked on Mikunis in my life, but tried to help, as did others in the garage. He eventually disassembled the carb, which was filthy, and blew out all the channels with carb cleaner, then we got the bike running but it still seemed very rich. Ultimately, we solved the problem with a Colortune -- a spark plug with a glass window in it, through which you can watch the color of the flame as you adjust the carb. (This is an English device that's well-known in the bike-repair community but may be more obscure to homebuilders. Check it out at R.D. Enterprises http://www.rdent.com. It costs about $40). On a Colortune you see that a proper mixture burns blue, and rich or lean burn yellower or whiter. This guy's bike was inconsistent, varying between blue and yellow. He traced it to an air leak in the manifold, and it now idles reasonably well (for an English bike). The Mikuni we were working on was a non-CV that specifically stated "Not for Aircraft Use" on the side, but they probably all adjust similarly. Among Brit-bikers, the Mikuni has the reputation of being a pain in the butt to adjust, simply because there are so many options -- I'm told there are 1000 varieties of needles available for it, with numerous tapers, holes, etc., as well as slide cutaways, pilot jets for the idle, and more, so if you know what you're doing you can zero them in perfectly. By contrast, the Amal has a permanently mounted pilot jet, 3-4 slide cutaway options, grooves on the needle for richness and that's about it. I'm happy to have a carb whose choices are limited enough that I may well stumble on the right one by chance alone, but ability to get it perfect is less than on a Mikuni. I'm reprinting below a post on setting up single and dual Mikunis on Norton twins that was compiled by a Canadian motorcyclist. For clarity, "Commando" is the standard Norton 745cc parallel twin, which was originally 8.9:1 or so compression. The "Combat" Commando bumped compression up to 10:1 and used a hotter cam (leading to serious reliability problems). Compression was subsequently lowered back to 9.3:1 or so and the engine bored out to 828cc instead. What applicability all this has to aviation engines is uncertain, but it may be better than nothing.

Mark I tend to agree that there is an over abundance of rudder authority on the KR-2. I never have had to use even 1/4 of the available rudder throw. In cross winds the wing tip will contact the ground much sooner than you will ever run out of rudder control. Mine seems to have plenty of response in all aspects of the flight envelop. My vote is you don't need as much as is provided, keep in mind that I am not an aeronauticle engineer. There may be other reasons for the amount provided such as spin recovery or other such unusual attitudes. Hope this helps Parley (currently rebuilding my 1835 after the second prop strike) On 23 Aug 98 at 22:07, Mark Langford wrote: RudderHeads, I really hate to set off another flurry of KR traffic, but I'm wondering about KR rudder size. Troy says he thinks it has way too much, and that he never uses but a small fraction of it. Yet I think I remember others saying it doesn't have enough. Could you real KR pilots cast your vote one way or the other on that subject? I'm trying to decide how to do my rudder balance, whether an aerodynamic with lead is the way to go or not (not that I can think of any OTHER way!). Hey, I could use a little more lead in my tail anyway...

You could use the F4U Corsair for an extreme example. I doubt when in the air or during landing the pilot used more than 1/2 deflection but just watch one take off. Looks to me like they use full right deflection during the first part of the take off roll. Cross wind landings is probably more of an issue for us. If you have longer gear legs that allow you to cross control the airplane a little more then more rudder is good but if the gear legs are so short that you can not lower a wing then most of the rudder is useless. I was looking at my rudder yesterday and it sure looks big! I think if anything I will just add a nice big Strake (ala C-152) if I need one. Speaking of C-152, ever notice how the vertical fin and rudder are about 4 to 6 inches taller than that of the C-150? - -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims SP290,..
