Bill here I found that the only time I got enough air in the wheel wells to feel it in the KR, was at high angles of attack,close to a stall.. I found it usefull in the overall feel of flying at lower speeds. The air hit the bottom of my legs.

In the tables for solid wood, basswood is approximately 2/3 as strong as mahogany in all modes. Basswood plywood will be approximately 2/3 the strength of mahogany plywood.

I got the majority of the layout of my web-site completed over the week-end. Now, all I have to do is build a KR-2S so I can have some content! ;-) The address is: http://fly.to/hangar-AP (add to your bookmarks) ;-) When you get there, click on the eagle to go to the KR-2S sub-site and feel free to browse around. (To get back to the front-page click on the eagle at the top-left corner.) I don't have any pictures yet and I don't have all the links created. If I overlooked any information you may have sent me or if there is any information that needs to be updated please send me an e-mail from the site. I want to include as many links as possible from my site to other KR builders/owners. There are still some pages under construction that have unresolved links ... just use the back button. Thanks, and I hope to have my e-mail account flooded from you folks! ;-) Best wishes to all, Albert Pecoraro Kentwood, MI 49508 616-281-3828 (H) 616-247-2803 (W) apec97@hotmail.com http://fly.to/hangar-AP <--- Now it's ready!!!

Yesteday, several of us were talking while I was pulling my oil screen out of the accessory case on my Cont. as part of the Annual. Carl Berge, who did a great deal of the design on Pipers and is doing redesign on the Arrow II, was going over the Piper Warrior my hangermate had just purchased. While he was commenting about various points in the design history, I asked him about Mike Selig. He knows Mike well and is very complimentary about his work. One thing I forgot to ask, and I will make a trip out to North Base, where he is working on the Arrow and reconstructing a Moth, to do so, is whether the thicker wing will change the center of pressure so other things might be affected. If this should move the center of pressure rearward relative to the CG, what other things might this affect??? Rex Ellington Rex T.

These will be made from 5/8" 7075 T6 aluminum. Overall they will push the axles about 10 1/2" in front of the main spar which is significantly improved compared to the 6 1/4" that you get with the standard Diehl Gear. They also give you 6" more height. However, everything has its cost - these will add about 4 lbs over the standard Diehl gear, but save about 1 lb over the same sized legs in Scotchply. I'm going to have these legs quoted and was wondering if anyone else is interested in having a set made. I'm hoping they will cost less than $65 each. Please let me know if you are interested in as the more that we can have made will decrease the per peice price. I can forward a drawing to those of you who can view .dwg files.

When I was down at Arlington at a flyin. I used to keep my cockpit always covered or cracked open because of the high heat buildup inside. This one day I left my KR with the canopy closed and the temp went up to 102 deg F, the Tygon shrunk and as luck would have it did not pop off at the top but at the bottom and I had about 25 liters of fuel in the KR. Fortunately, 100LL evaporated quickly and I had no smell in the a/c. Did bugger up my leatherette upholstery which I had to replace. Talked to Jim Scott Jr. and he said they never use Tygon on anything and that it was not a very good plastic. As he is a dealer for ultra lights he gave me a short piece of what they use which was nothing more than snowmobile gas line, and I never had a problem since. That is my experience with Tygon, KISS is the best way to go. 73, Ross Youngblood wrote: > > >> > > >>In looking at the pictures kindly provided by many of you I see a lot > > >>of excellent workmanship.

Are the wing stub skins > that RR sells usable with the new airfoil design? The main spar still sits on the longeron, but the aft spar comes up some amount (seems like it's about 1.5" but I won't swear to that til I check it. Maybe you mean if you go with the 18% version, which does require a "taller" spar on the order of 8.5". I worked on the 16% version last night and fixed it so that the rear spar is still 4.0" tall, while the front spar grows a little to 7.3 inches tall. That gets the main spar in the 25% range and keeps aileron chord closer to stock, a generally better match than what I had before, but either way will work fine. The RR wing skins are way too rigid to ever conform to a different airfoil. By the way, Steve Eberhart deserves all the credit for these new airfoils. I was planning on using a different version of the NLF. He questioned whether or not it was right for the KR, and asked "why not get the guys that designed the NLF to design one specifically for the KR?", and then he did exactly that. Not only did he talk them into doing it, but followed thru and built the wind tunnel test wing sections as well.

Are the wing stub skins that RR sells usable with the new airfoil design? >> The 16% chord wing uses the same main spar as called for in the plans, as Mark said, there is a slight difference in the contour of the spar cap. I believe that even if you have contoured the cap it will still be fine. The rear spar is where the change is as it is mounted about 1 1/5 inches above the attachment point called for in the plans. Mark can give you more precise measurement that "about". Troy should be flying is plane shortly, so if you haven't mounted the rear spar yet, just hold off. If you have it is easily removed and repositioned. The RR stub wing skins are the RAF48 airfoil and will not work with any of the new wings. I'll repeat myself the sake of a better airplane...............it you are building your spars or have done any foam work on the wings, hold off and look into the 16% or 18% they will be the future of KRs. Your plane will fly with it's nose straight ahead, you will get better cruise (speed for the same power and fuel savings) without sacrificing anything.

He pulled the foam hunk out, trimmed it with a knife, slathered on soe epoxy and pushed it back in. Couple of layers of epoxy/glass and it was done. It looked to me like sandpaper was not in his repertoire. 0 Does anyone know if the higher incidence was perhaps intended so you could three-point the plane on the retracts without hitting the tailwheel too soon? ---------------------------------------------------------------------- Subject: Re: Nav.

The sandable foam is usually urethane. if you hotwire it, it reportedly releases a poisonous gas. DO NOT HOTWIRE URETHANE FOAM The hotwirable foam does not sand well..is often blue or whitish. Hotwiring is fun. Someone else here did hotwire his wing foam. They are basically solid with some portions cut out internally. I suspect that his wing will be rigid and strong with minimal extra weight.
