Over five years I could build a complete new S airframe and have money left over for the cost savings. I am actually guessing that with a good cover I could get almost as much time out of the airframe as if in a hanger. The wood is all varnished and plenty of wood and fabric planes have been sitting outside since they were built in the 40s. This is all theoretical since I don't know of any others kept outside yet. With any luck, I will be living at an airpark in a year or two and i won't have to worry any more. -------Original Message------- From: Kenneth L Wiltrout Sent: 07/06/03 07:42 PM To: engalt@earthlink.net, krnet@mylist.net Subject: Re: KR>Airport woes > > Brian I really don't think this type of aircraft will do well being outside on a permanent basis.

I apologize in advance. My name is Richard Alps, I'm 63, I've had a set of KR-2 plans for, ... oh ... maybe 25 years. I want very much to build a KR-2S, and I'm fond of M. Langford's work (when does this guy sleep ... or work???). There is something that I believe is missing from this web site, and all the fine people who share in it. I see lots of stuff on the techie side, and the aeronautical side, and most all the sides you can think of. But there is one area of my own personal flight experience that I don't see anyone broaching. I refer to ye olde check lists. I was trained at a Cessna Pilot Center, probably like many of you. After all, you go to your local airport and ask to be taught how to fly one of those wingy things. If it is a Beechcraft FBO, then that is most likely what you start out in. Next thing is, that I have never owned my own airplane. Therefore, all my time has been in rentals, again, mostly Cessna. I do have some Piper Cherokee 140 and 180 time logged. And altogether I can account for something like 400 total hours in the air. Zero in the last 10 years. Ouch!! Anyway, when you approach an airplane that God knows who flew the last few times, then you owe it to yourself to really be certain that the bird will take you up, dance you around, and bring you back SAFELY!!! Ergo, the check list. I can't believe that I would ever climb in any airplane without having walked around it and physically demonstrated to myself that a full collection of specified items have been determined to be in good order. Period!! To this end, I have looked among my box of old belongings, and I came up with a Cessna 1978 Operators Handbook for the Skyhawk 172. I turned on this computer I am using right now and copied three or four check lists into Microsoft Word 2000. It fills two type written pages, and the only thing wrong is that the information is not for a KR-2 or KR-2S. If you climb into a Skyhawk, you can just about bet that the check lists will be very close for almost any age of bird, but I think that this could be less true for our dear KR-2 and KR-2S airplanes. Its because each is a unique airplane. No cookie cutters here. Back to the checklists. I would be happy to e-mail an attachment of these lists to anyone who would like them. The real thing is that they need to be modified for the KR. Most of you are much further along in the construction phase than me, and I think most of you would do a better job of converting the checklists for KR use, don't you agree? I think at this time, the only thing left is the question of whether or not you agree that having and using checklists is appropriate and necessary. I have absolutely no desire to mess around being judge and jury here, and I see no need to. Every single one of us that flies, knows and understands the concept of PIC. While you are up there, not the President of the United States, not even your WIFE can tell you how or where to fly that plane (well, she can TELL you...). You are the last and final determining factor. And so it is with any checklist. It is just that I learned to fly with them. I welcome any response (boy, that was stupid!!). Really, if you want to comment, go ahead. If you're interested, I can forward what I have (taint much). If you have something that everyone can benefit from, contact me on the net. To save this net, you can contact me personally at either: richardalps@aol.com or richardalps@msn.com Thanks guys and gals. As a very dear friend would tell me about now, "you stuck your foot in it this time." I wind up introducing myself at Town Hall Meetings this same stupid way. I have no idea what ails me. Gaaaack! I KNOW they don't teach public speaking like this. Sorry. Richard G. Alps Littleton, Colorado PS. Plan to see some of you at Red Oak, Iowa this year.

Most people will have different canopy latches, different fuel systems, different avionic systems. I'll give this as an example. When we started Jeff York's newly bought KR for the first time, figuring out the fuel flow system within the cockpit was the first order of business. As I recall three different fuel flow valves were inside the cockpit, along with a drain. Some basic items such as aileron ckeck, elevator check, rudder check, prop, etc. on the outside and items such as oil pressure check, amp check, fuel check, trim check should be standard there will no "one size fits all" list. Make one up, I'll have one, you wouldn't believe the number of RV tipup canopy flyers have there canopy open to the 4" mark because they forgot to latch the handle behind their head. How much building time would it take................what, an hour to make one up!! Dana Overall 1999 & 2000 National KR Gathering host Richmond, KY RV-7 slider/fuselage Finish kit ordered!!

WHAT THE HELL WAS SOMEONE THINKING??? Page 87 of the KR2 plans give the written instructions for mounting the hinge with " 8/32 pan head bolts with nut plates spaced 6" apart". Before cutting the wing open to correct you might consider using a hole saw, held at an angle to cut a semi-circle access hole every 6" on both the aileron and wing panel. You really only need access to attach and flox the nut plates. Make the holes on the bottom side, insert a foam plug when finished, and cover back over with a layer of glass and refinish. If the hinge alignment is o.k. now I'd remove and replace half the rivets at a time to hold alingment while you are correcting the problem. Good Luck.

It sells for about $4.50 a foot and you can make it for about $1 a foot. I came across this info at one of the Gatherings. To build mine I cut 4 foot lengths of 2" fiberglass tape. Lay on plastic and squeegee in the high temp RTV. When first layer of tape is coated add a second layer of tape and coat it. I used 4 layers of tape and that seems just right. When the top layer is coated, flip the 4 layers over and coat the bottom side. Allow to cure and trim excess RTV from the edges with a sharpe scissor. You can't tell this stuff from the seal material you purchase.

That's >what I intend to do anyway. Rick Wilson. ++++++++++++++++++++++++++++++++++++++++++++++++++ That would work but the tie-down points are very close together. The distance between tie-down ropes/chains at the airport is generally equal to the wingspan of a KR2. If you wing tip is still open, hook a 1/8" piece of alum angle(or steel) over the end of the lower wing spar cap, flox, and allow a portion with a 1/2" (approx) hole to extend below the wing. How much drag could this produce when aligned with the slipstream?

Your money would be much better spent going that route than turboing an 1835. You will need to go into the engine and adjust the compression ratio, add a dual oil pump and many other modifications to end up with a reliable turbo installation. When I put the turbo on my TypeIV engine there were no turbo kits available. I had a custom turbo built by AirResearch, purchased stainless tubing to make up the exhaust system, had to buy a TIG welder, take a welding class, purchase a Nissan intercooler, modify the intercooler to have aluminum end caps rather than plastic, plumb the intake side, oh goodie, I get to learn aluminum welding, build extra large cowl flaps..... You get the picture, putting a turbo on a KR is not trivial. It drives a lot of other decisions that end up making the project take a couple of years longer. If you like building more than flying, by all means, turbo that 1835! If you want to fly, call Steve and order the 2180 upgrade.
