I think you are right that equal fuel flow > should be expected, but there are a lot of factors in play here. Incidently, I have come in the habit of refuelling (when I have time) only from the right wing's side. I fill to the top, then wait. After a few minutes, the fuel level has gone down as it flows into the left wing's tank. The I top it up, again. By doing that, I check that fuel is really flowing from one wing tank, to the header tank, and the other tank. No foreign body has blocked the lines to the header tank. When, after that, I check the fuel for water, from the gascolator, ahead of the firewall, and the fuel is running out in my sample glass, I know that the fuel system is relatively ok.

My kit manufacturer says it's not necessary. Lift acts like a giant vacuum cleaner, exerting a peeling force on the top of your wing. You have to do something to hold your fabric on other than just gluing it. Pop rivets, screws, clips, and rib lacing are designed to secure fabric for long service lives.

    Subject: Re: fuel flow
    --> Kitfox-List message posted by: "John Stoner" <john@dakotacubaircraft.com> Marco, I noticed this same uneven fuel flow when I started flying my KF III. By experimenting I found that I could control which wing tank drained faster by flying with one or the other wing slightly high, that is, in uncoordinated flight. I then chose to ignore it until I gained enough experience to start landing on the beaches and gravel bars. Then when the plane was parked with one wing low, and more than half full tanks, the fuel would flow from the upper to the lower and out the vent. A shut off valve in each wing root solved the problem, but added to fuel management awareness. I now have three fuel valves; left wing, right wing, and master under my left thigh. I did not follow the manual in installing the fuel system. I thought it was to complex, going to the firewall, back to the center mounted valve, back to the firewall, etc. Also the fuel system was in too close proximity to the exhaust system. I routed the fuel system down the left side of the fuselage, and modified the exhaust system to be entirely on the right side of the engine. This had further benefit in being able to place the fuel pump for best efficiency rather than prioritizing dodging the exhaust system. Regards, John Stoner KF III, 582

    --> Kitfox-List message posted by: "Lowell Fitt" <lcfitt@sbcglobal.net> I understand. One of our frequent companions had a Coyote. Since another airplane was slowest in our group, I can't speak as to his relative performance. I do know that he could land very short and his climb was excellent. Especially after he put on the CAP 140. He sold the airplane as it was just sitting around waiting for the hub upgrade.

    Subject: Re: RE:prop pitch
    --> Kitfox-List message posted by: "Don Smythe" <dosmythe@cox.net> Using other peoples numbers depends largely on where you check the angle. I use 20" from the hub (about 3/4 length) as a reference point for all my settings. That is, place a measuring device on the front of the blade and push it toward the hub until it makes contact then mark 20" on the blade. Right now, my blade is set for 27-3/4 degree with the tailwheel on the ground. This number will change up to a degree or two (forget) if you move the measuring device 1 inch either way on the blade.

Off the ground 400 to 500 feet and climb is 600 to 800 fpm . Off glassy water in 300 to 400 feet and shorter on rough with wind. On wheels 1200 to 1500 fpm climb and crusie in the 90s Your best advice assuming you know how to set your pitch is set for static rpm of 6200 rpm. That is tied up not moving engine warmed up and you should get 6200 rpm , once rolling it will climb to 6400 to 6500 on climbout. Rotax 582 does not get it's full HP till 6200 so by setting it any less you missing out on HP plus hard to tune if you not cranking Full HP.

    Subject: Re: Rib Stitching
    --> Kitfox-List message posted by: "Lowell Fitt" <lcfitt@sbcglobal.net> Thanks Ron. It didn't occur to me to go to the website. As you might recall, this subject arose as a builder having already covered and painted was asking if he needed to ribstitch which would have resulted in essentially refinishing the wings. There are a lot of Kitfoxes out there flying without ribstitching, however, and it's absolute necessity might be open to varying opinions in our application, especially since the incidence of fabric separation from a cap strip resulting in an incident sappears to be zero. If I were in the business, I most certainly would recommend the suspenders along with the belt, but not only on the website in the FAQ section, but in the covering manual. I just couldn't find it in my manual. Incidentally, they also recommend ribstitching all control surfaces, I didn't ribstitch those and am not particularly concerned about it.

    Subject: Re: Rib Stitching
    --> Kitfox-List message posted by: John Larsen <jopatco@mindspring.com> Hello: I think a good way to look at rib stitching on a wing designed to not need rib stitching, is to consider Jim Osborn efforts. Jim is my neighbor here in the skypark and had a career as an aeronautical engineer for Northrop. He is also the designer of the Acro Duster. When he built this style of wing he made his own ribs designing them with 1/4 inch cap strips, as he was going to rib stitch. If you are going to rib stitch you do not need one inch cap strips. All aircraft like all the Pipers, military planes have narrow cap strips and were designed to have rib stitching or other mechanical devises to hold the fabric in place. One must have whatever retaining method listed by the manufacturer when you cover these planes. I get bored very fast rib stitching and don't like adding the little ridges to create some drag across the width of my wing. I don't rib stitch and have over 850 hours on my wing and have hit over 140 mph IAS without incident. When I cover an under cambered wing like the Avid and early KF I do use stainless steel staples on the underside of the wing as the fabric can pull loose in this area. It happened occasionally when I was working at the factory we had a procedure to take the wing off and re attach the fabric. No flying mishaps came from these incidents, however if you let it go long enough the fabric could open a seam, rip and foul the flaperon. Maybe that what happened in the accident reported to the NTSB. What really gives strength to the wing is the shrinking of the fabric. It is the vise like grip exhibited by the shrunken fabric that holds the wing together, not the glue or rib stitching. Rib stitching or other means of retaining the fabric are necessary in a case of a puncture in the fabric like a bird strike. The rib stitching will keep the fabric from ballooning from air pressure and or having the puncture lead to a large section of the fabric being ripped off. Dean Wilson, designer of this style wing, said the wing would be just as strong if you put no glue on the ribs where they attach to the spars. An engineer and friends tried it and found that what Dean said was true, the unglued wing was a strong as the glued wing. The fabric was well glued during this test. Your Truly For about 20 months when we will most likely go through this tread again.

    Subject: Re: Rib Stitching
    --> Kitfox-List message posted by: "Ronald K. Stevens" <rkstevens@verizon.net> Yep. I plan on rib stitching my control surfaces as well as the wings. Given my engine/prop choices, I'll likely have one of the faster ones anyway. And, like they say...the rib stitching never hurts. But primarily - aside from the belt and suspenders approach - I plan on rib stitching everything simply for the peace of mind. I'll just never have to worry 'bout it. Besides...it looks cool :-) However, if I had a flying 'Fox that wasn't already rib stitched...And given the amount of Foxes out there that are not rib stitched. I wouldn't worry about it. Just give a thorough preflight and keep an eye on it. Like you said, there is little statistical evidence or empirical data that would cause me to worry. There just aren't any KitFox's falling out of the sky due to fabric de-bonding.

    Subject: Re: SV: Bungee Cords
    --> Kitfox-List message posted by: "Rex & Jan Shaw" <rexjan@bigpond.com> Hi ! Guys, I'm no bungee expert as I have Grove gear but the following is from Service letters on the Skystar site. Perhaps it helps clarify some questions. Rex. Service Letter #20 SUBJECT: Shock Cords FROM: Denney Aerocraft Company Dear KitfoxT Builders, Over the course of the past several months, good quality shock cord has been increasingly difficult to obtain. The shock cords (LSC-19) included in your landing gear kit may be fabricated of one of three different types of bungee material. Some of this material is of smaller diameter than the original stock. You may have to take more wraps than indicated by the instructions, Step (22) and Figure LGH-6. The original material is .41" diameter and color coded with two rows of black threads and one of red. Install it according to the manual (six wraps). The smaller cord is about .33" diameter and marked with 3 rows of green threads. You will have to take about eight wraps. It seems to be good quality bungee material and should work just as well as the original. For a time we sent bungee material that has proven to be of inferior quality. It is about 7/16" (.41") diameter and marked by paired bands of red and green. These shock cords do not last at all. Return them to the factory and we will be happy to replace them with the better - quality cords as soon as possible. Happy building Dan Denney rexjan@bigpond.com

    Subject: Fw: M4-912 overheating
    --> Kitfox-List message posted by: "Chuck & Deanna Schieffer" <cdschieffer@starnetdial.net> Hello fellow Listers, I have a M4-1200 with a 912 in it. On climbouts to about 2500 feet the engine oil temp gets up to about 230 to 235 with the coolant temp about 210 in a 75 degree day. I have an earls oil cooler and oil and coolant levels are full. I usually throttle back to about 4800 to 5000 rpm at about 2000 feet to keep the oil temp below 230. Any time I go to full throttle for extended times, (10 Min or so), the temps come up. The top of the coolant radiator is about 1.5 inches away from the belly of the a/c. I use the orange coolant but talked to Lockwood about using the new Weaver coolant. They indicated that my temps won't change, it just cools the cylinders better by reducing/eliminating air pockets in the coolant passages if I understood them correctly. I understand from the list that I could move the radiator down further into the airstream but I am wondering if anyone has ever used any baffling under the cowling to try to force more air through the cylinder fins. It looks like the air path of least resistance is over the top of the engine and out the bottom. Any thoughts on reducing temps on high power settings??? Thanks in advance, Chuck

    --> Kitfox-List message posted by: "Jay Fabian" <experimental208nd@comcast.net> Hi Chuck, I have the same set up. 4-1200 912ul. I actually have to put duct tape over the radiator and oil cooler. Factory set up. Even at a 75deg day to get the temps near 200 deg. Some thing else must be up with your engine, maybe some one can add to this. thanks Jay F. ----- Original Message ----- From: "Chuck & Deanna Schieffer" <cdschieffer@starnetdial.net> Subject: Kitfox-List: Fw: M4-912 overheating > --> Kitfox-List message posted by: "Chuck & Deanna Schieffer" > <cdschieffer@starnetdial.net> > > > Hello fellow Listers, > I have a M4-1200 with a 912 in it.
