KRnet> Retract Axles

Jim, I have the wheels and brakes that I removed year’s ago. I don’t think they have ever been flown. I’ll check to see if the axles are with them. Call or text, Pete, 503-710-4618 Sent from my iPhone -- KRnet mailing list KRnet@list.krnet.org https://list.krnet.org/mailman/listinfo/krnet

KRnet> KR for sale in Oregon

I have picked up another Champ project and I need to part with the KR. I consider this to be still a project. It is still in phase 1, 1835 VW (balanced), Forward tilt canopy (from RV12), modified Cheetah gear legs, Rudder area increased 26%. All gages stay in the green during flight tests, typic

KR>KR for Sale

I have lost interest in my KR. I decided in 2016 that is I wasn't flying the KR comfortably by June that year I was going to purchase a plane I can fly! I bought a 1946 Aeronca "fun flyer", not much to look at but a solid plane. I don't get anywhere fast but I do get anywhere! and I'm loving i

KR> Pacific Nortwest Mini Gathering?

I would be interested in a NW Gathering. Depending on the interest, I would suggest Lenhardt Airport (7S9) Under a shelf in Aurora's (UAO) airspace but I'm not sure there is hangar space for the planes that attend and and it is 15+ minutes from the nearest motel/hotel. there is a shower and I w

KR> KR Project for sale/trade

I have a KR 2 Project that I started in the early 80's That I need to get out of my shop. It has a been widened 4" lengthened one Bay (I think 11"), has spar location altered for AS504x (6 as I recall) and a dragonfly Canopy These mods were made before the KR2S eas released (not the airfoil

KR> Glassing Tiger Gear legs

Phil, Structurally the added layer is not necessary but it will protect the real fine uni on the surface. I added a styrofoam leading and trailing edge then wrapped with one layer of 7533 (KR cloth) including all the flat surfaces with bolt holes. I then filled the flat between the leadi

KR> rudder stops

"Hey Guys, Looks like I'll be doing Rudder stops as an afterthought. What's the best place and method for this ?" I don't often contribute but I think this time it is important. My take on this is; I am installing stops at both ends. The reason: I hear it is accepted good practice to s

KR> Subject: center spar analysis

I checked my work in the morning!! The real answere is...I=66.7 in4 (2774.3cm4) so Z= 25.7 in3 (421.1cm3) does this sound more resonable? Pete Original Message - From: Pete and Karen Gauthier<mailto:gauthier0421 at msn.com> To: krnet at list.krnet.org<mailto

KR> Subject: center spar analysis

Has anyone tried computing the section modulus of the front center spar? I should probably wait until tomorrow to check my work but I get I=36.7 in4 (152.7cm4). Z = I/c so Z= 10.2in3 (41.5cm3). I used dimensions from my CAD drawings and they are before any trimming for the airfoil but I thi

KR> Gear Legs

This thread started as a request for the dimensions for the Diehl legs. The Rand Robinson Engineering legs being replaced are 7075 aluminum, very similar to the one Steve just described and the mount/bracket is cast aluminum (very stout cast aluminum). The legs angle out at 22 deg. (not much

KR> fletchair gear legs

Thanks Peter, I have a set of these legs and I heard that someone has done just as you suggested, cut them in half, but I don't know how that worked out. They are 1" thick. I don't think it would be good practice to reduce the thikness not having any information on the stacking and I'm af

KR> LANDING GEAR LEGS

I had a mishap involving a broken rudder peddle assembly and partialy developed ground loop (partially developed because at 90 deg. the gear legs parted the aircraft and terminated the loop). I have the Yankee legs and I am trying to determine a spring constant to design my replacement legs.

KR> First Flight

N424DG is no longer a hanger Queen! I want to thank Ed Stepec, a fellow EAAer and former KR Owner. He did the taxi testing and flew the first flight of N424DG this evening. from the ground it was a perfect take off and a perfect landing. It was a short flight, only 10 minutes but he reported

I have concerns about passing a medical also. I contacted an EAA Pilot Advocate and had a discussion about my options. See the following website http://members.eaa.org/home/medical/. The physician I talked to assured me that it is highly likely that I wou

KR> Laminating spars

I think Peter Johnson and Sid Wood make good points, orientation does matter but in this case I believe the difference is insignificant. The spar is in bending but as Peter pointed out the caps see very little bending hence very little shear due to bending (sometimes referred to as horizontal s

KR> Re: Question about spars on 2S

Hi Buzz, Do these spars have a finish on them and is it the finish that is crazing or is it the wood? There should be no finish on the top and bottom of the caps because that will affect the bond of the fiberglass skin. Your choice of the words "the stub spar have checking cracks" is interesti

KR> Spar holes

I have a question. ..snip My opinion on spar holes. The dowel solution is fine in a the compression zone but only increases stability in a tension zone. My opinion is to to make every effort to reuse existing holes. If that cannot be done, dowel plug all holes and move outward on the spa

KR> Manifold Pressure

I'm getting close, I might be able to make the next gathering. right now I have another question. I am installing a manifold pressure gage and would like some suggestions for locating the source. I have the HAPI intake ducts with an aerocarb. I am considering welding (or brazing) a half coup

KR> VW dip stick

I have a HAPI 1835 with a Rand Cowl. The dip stick is easily accessible through the air intake but it cannot be removed without removing the top of the cowl. How do those that are flying VW access the dip stick. do you Modify the dipstick, cut a door in the cowl, remove the cowl? Any adverse

KR> HAPI spark plug wires

I am reinstalling the 1835 HAPI engine and two of the Auxiliary (automotive) plug wires are to short for my comfort level. Making a new set of wires is not a problem but... Does anyone know how HAPI formed, or recommends replacement of, the seal on the plug boot? Thank, Pete Gauthier Woodbur
