Camp Scholler........hum, the only places left will be out by the road. Find any spot and have at it. Bring along a small burner, a pan to boil water and a box of coffee singles if you are of that type. I like my coffee first thing in the morning to get the system working. It will be a hike to get coffee if you don't bring your own. I also plan breakfast and dinner at the campsite. It gets very expensive to eat out every meal. Showers, if you can get by until lunch time, the showers are much less crowded than first thing in the morning. In the morning, plan on standing in line. Buy some bottled water before you go. Bring an empty bottle around with you and fill it up at the various water stations. A bottle of water will cost you an arm, leg and maybe someone else's leg to buy on site. Take the trolleys, they will save you untold miles of walking. I run everyday, but your feet will take a beating trying to cover all the grounds. Don't miss the vendor buildings, lots of neat.......and expensive stuff. Find the outdoor used stuff guys, the early goers can find some good stuff. The late comers still might find something they need. On a personnal note, don't know how deep you want this to go, I wear a fanny pack with some toilet paper in it.................never know how "stocked" the porta pots are with essentials. They do have that John Wayne toilet paper........Rough, Tough and don't that sh#t off anybody!! Sorry, just had to go with that:-) Enjoy and have a good time. Look at other airplanes than what you are building. You will find some neat ideas people have incorporated. Dana Overall Richmond, KY RV-7 slider/fuselage Finish kit ordered!!

I could have probably gone a few more gallons in the wings but 29 gallons should be more than sufficient unless you are building a single seater with a big fuel hungry engine. Oh, one thing I forgot. The forward control cable for the aileron runs just behind the forward spar so you obviously need to cut the foam there so the cable doesn't hit the tank. I had my plane hanging upside down so the elevator hung in the full up position which meant the stick was full back and the aileron cable was in the full forward position. I almost didn't realize that the cable was going to rub against the glass on the tank when I pulled the stick back. Make sure you have clearance with the stick in any position. I also put a vent tube in each tank. I drilled a 1/4" hole at the forward corner of the tank in the bottom and floxed in a piece of aluminum tube that was bent forward on the bottom of the wing. I also made an indention on the back corner of the bottom foam plate and after it was glassed I took out some foam and epoxied in an aluminum fuel tank flange so I could put in a strainer.

My opinion, for whatever little value it is, build the fuselage according the freakin plans with the material recommended and tried. The other parts, there are now tons of documented pain free alterations that will not take you nearly as long to do as those of us who went the documentation phase of construction. The fuselage is a pretty straight forward and structurally sound piece of the puzzle. Can you improve much on this part of the airplane? I think not. The exclusion of the Banana Boat in the building process only flattens the top longeron, not an issue with a composite airplane. Take Jim's KR or Tom Crawford's prior KR, great flying airplanes. BTW, I still can't believe you said that:-). I'll check Mark's pulse when we meet up Tuesday night somewhere around Oshkosh.............I'll let everyone know.

For those that have been keeping track, this is the fourth major move since the KR project started... but the plane stayed at the airport this time. (At least until the next move). I just had a pretty good day of KR work. My wing tanks were seeping around the metal flange where the Capacitive fuel senders were, and I was sort-of fed up with working in fiberglass, so it took a year to get to it. (Work, Moving etc also was a factor... not to mention that I live 92 miles from the airport now.) I've got a really good 1 man rigging system set up for my KR. I have a wing dolly that both wings fit on when they are not on the KR. I also have a seperate wing installation jig that consists of two pressure treated 2x4's on wheels with removable carpeted stand offs. One end is reversable so that you can switch from left to right wing. One of the things I engineered into my KR was quick release fuel fittings on the wing. With these and the dollys you can attach and remove the tanks without draining fuel... up until now I had self draining tanks so I haven't tested this much yet with full fuel. I've had this setup for a couple of years now, and it seems to work reasonably well. I will take some photos and post it (soon?)... http://N541RY.com is off the air at the moment, but as soon as it's back I will have new photos. After putting the wings on I made a couple of calls on the radio from the KR to order fuel... if everything works as well as the radio setup, this is going to be one terrific aircraft when I finally get my life in order so I can finish it! Had the fuel guy put 6 gal in each wing tank. Last fall I had them topped off, 11gal each, and with the seeping saw most of the fuel go by-by. I did some searching on the web last year and found a good motorcycle site that had instructions on how to clean and repair fiberglass motorcycle tanks. Basicly, you buy some MEK, slosh that around until it runs clear, then clear that with Acetone. My tanks hasn't really had enough fuel in it to get dirty yet, but I thought running some MEK in them would be a good idea. After cleaning my tanks, I set them up for some light pressure testing with my air compressor. I have a nifty vacuum/pressure gauge that I put on a AN barb fitting with 1/8" thread. This was installed at the fuel drain point. The air compressor was connected to the fuel outlet, and I put tape over the fuel vent, and removed the fuel senders and taped that over. I pressurized the system slightly, just before the pressure gauge moved, then started listening... sure enough, I heard sound coming from the fuel sending flange area on both tanks. A few months later...I get out and mix epoxy. I decided to thin it a bit with MEK. MEK is an epoxy thinner... available through Aircraft Spruce or the Hardware store. This made the epoxy into kind of a sloshing sealer... then I poured this into the tank, and sloshed it around. (Remember to pull your sender, and fuel strainers etc... you don't want anything plugged with epoxy.) I had the fuel sender AN3 mounting screws installed, so the holes for that would not get plugged, and tipped the wings up on their end. After sloshing for a bit, I applied air pressure to see if I could force epoxy out through any holes... sure enough it worked like a charm! I pressure tested both tanks last week to about 1.5psi and only heard hissing out through the fuel filler neck. CAUTION: Tony Bengellis does not recommend pressurizing your fuel tank with air (As I recall). You could potentially de-laminate it if you don't watch what your doing. After a week of curing, there was some minor dremel work to open up the hole in the fuel sender flange, but otherwise no Homer Simpson "DOH" moments. This all ended nicely with me making some nice radio calls today "Corvallis Unicom Experimental fife four one romeo yankee, on the ground, request". Fueled around noon. No fuel dripping or seeping on the floor of the hangar as of late this evening (6:00PM). We stayed in town so I could check it... then did the 92 mile drive home North to Portland. (Yes I've moved again...) There is a slight chance that due to the wonderfull economy, I may get to move yet again before this is all over with... Texas is the next possibility Dallas or Austin. Won't move unless I can find a nice place for my KR to live. When I do finally fly to the KR Gathering, the KR will have more road miles than air miles... With the wing tanks properly sealed, I should be able to proceed with taxi tests, without being a major fire hazard in the hangar. -- ____________________________________________ http://www.operamail.com Get OperaMail Premium today - USD 29.99/year Powered by Outblaze ------------------------------ Date: Sun, 20 Jul 2003 05:14:53 -0500 From: "Max Hardberger" To: "KR builders and pilots" Subject: KR>EDUARDO'S KR-2 WEB-SITE TRANSLATION Message-ID: <001a01c34ea7$c3e55f00$0100a8c0@toshibauser> References: <5a.1f8cc31d.2c4b3de7@aol.com> <020101c34e58$3ba67880$1202a8c0@basement> Content-Type: text/plain; charset="iso-8859-1" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Precedence: list Message: 16 HERE IS A ROUGH TRANSLATION OF THE FUSELAGE SECTION. IT APPEARS THAT HE USED 3 LAYERS OF GLASS CLOTH. IF ANYBODY NEEDS ANY OTHER PART TRANSLATED, LET ME KNOW. MAX HARDBERGER NEW ORLEANS Translation: After sandpapering all the left-over glue, I began to cut the polyurethane foam. In this case I am using foam of two densities, 40 and 50 Kg./m3, in different places on the fuselage. For the curves, I used a foam plate of 50 mm and fitted them to the finished form of the interior, so that after gluing them in place, the work to sandpaper them was reduced. For the tail wheel strut, I made reinforcements of cedar, because with the impacts that it receives extra strength is necessary. Also, to complete the foam blocks I cut it in the center vertically and laminated it with the same 3 layers of glass fabric and epoxy, then placed it against the block to stick it in place. This way I obtained extra stiffness for the whole structure. Once all the foam was glued in place, sandpapering the outside was the next step. This is one of the pleasant parts; in approximately 40 minutes, the foam was transformed into the silhouette that I had envisioned for such a long time. ------------------------------ Date: Sun, 20 Jul 2003 10:14:46 -0400 From: Brian Kraut To: Rick Wilson Cc: KR builders and pilots Subject: Re: KR>CONVERTING KR-2 TO WING TANKS Message-ID: <3F1AA3D6.30308@earthlink.net> References: <20030720033111.13192.qmail@web21202.mail.yahoo.com> Content-Type: text/plain; charset=us-ascii; format=flowed MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Precedence: list Message: 17 Either I have three wings or I can't add!
