We pulled the engine down and the rings had NO spring left in them. The eBay ad says they have kits for both 582 and 583. Maybe you got the wrong kit? I tried expanding the photo in the eBay ad to see more detail of those pistons and I couldn't be sure, how many ring lands there were. Are the pistons supposed to be a forging? That might account for some of the reason they are so expensive. -------- Paul A. Franz, P.E.

We pulled the engine down and the rings had NO spring left in them. They looked good when they went into the engine. The cylinders were precision honed and the ring end gap was fine. After the break in and a little over an hour in the air, I noticed a loss of power especially at takeoff. I made a quick turn around the airport at less than half the pattern altitude and got her back on the ground. I shut it down and jumped out and gave the prop a spin by hand and I may as well have had a turbine in the nose, there was virtually no compression. Thanks for the advice. I am going to shoot him an e-mail and see if he can send some closer pictures, and see if they are single ring, or doupble. I noticed he does have diffrent kits for 582 snomobile, 582, and 582 aircraft. I assume that there is some diffrence, although he could be selling all the same thing, and just changing the price. I will let you all know what I find out. If these are double ring, made for aircraft 582, they may be a good deal.

    I just got a message back from the seller. He refered to them as "aerolites", so I am not sure if that is a brand or what, as I can't seem to find any other info on that brand name. Anyway, he said they make an aircraft version, and a snowmobile version. The aircraft version is a single ring though. Whay would an aftermarket company make a singel ring version? Leonard, I am interested in more info. from you. Was this the exact same kit as you got? Same seller? After you tore it back down, was the ring the problem? Maybe the piston is good, but jsut needs a better ring? At the price of this kit, it is 2 pistons, rings, and a whole gasket set, for about the same price as just 1 piston with rings costs elswhere. Hard to pass up a deal like that, but it is probably too good to be true. Andrew Read this topic online here: http://forums.matronics.com/viewtopic.php?p=217756#217756

    From: "LarryM" <CrownLJ@verizon.net>
    After 71/2 yrs (300hr) on my 582, I decided to pull it down and look at it for the first time. I can happily report that in all aspects, the engine spec'd within new limits, or just outside new and well within wear limits. (Rotax repair manual specs) The outer main bearings were a bit rough, and thus replaced. I replaced 4 bearings (Rotax - airplane) ($314 delivered) and a gasket kit ($84 delivered - Mark Smith) for a total investment of $400. That's 7 1/2 yrs. or $53/yr. I couldn't even come close to that on my Lycoming. I'm not trying to start an argument, I just wanted to post facts. When manufactures list TBO like 2000hrs or whatever, it doesn't mean that many hours with no $$ spent, but just when the parts might be worn out. my .02 larry Read this topic online here: http://forums.matronics.com/viewtopic.php?p=217808#217808

    Subject: sight glass fuel indicator?
    From: "WurlyBird" <james.t.trizzino@us.army.mil>
    I am happy to announce that I have finally purchased a Kitfox III that will be waiting for me when I get home from Afghanistan. My buddy that did the test flight and inspection for me indicated that there were no fuel gauges on the wing tanks, 6 gal variety. John McB has told me to check if there were holes that were covered because he thinks there might have been some on that style fuel tank but he had never seen an install done after assembly. For right now I am guessing worst case and assuming there is not. Has anyone ever installed or seen/heard of an installation of a sight glass or sight tube type fuel gauge after the plane was assembled? Right now I am thinking that it should not be too hard besides having to work partially through the fuel cap opening and ensuring no debris remains in the tank. Am I completely wrong? Is there a good kit or specific sealant for something like this? Any information will be a great help. Thanks James -------- Prospective Kitfox buyer Here for information on airframes and engines Read this topic online here: http://forums.matronics.com/viewtopic.php?p=217836#217836

You might not need to go to the trouble of installing a sight glass on the wing tanks. The header tank may be large enough for a comfortable reserve. You might be able to see the fuel in a clear line coming from a wing tank and if the header tank holds enough for your reserve requirement then that could be sufficient. You could also install a low fuel alarm in the header tank. Some of the header tanks hold half an hour or more reserve. You might also talk to the previous owner and find out what his procedure was. -- Paul A. Franz Registration/Aircraft - N14UW/Merlin GT Engine/Prop - Rotax 914/NSI CAP Bellevue WA 425.241.1618 Cell

The worst case is you will have to drill and tap the two holes to install the site gage. The main Issue will be getting all the debris out of the tank. A trick is to grease the drill bit so the debris stick to it. An adapter on a shop vac would probably work but you may get the "Big Bang" from fuel fumes.

    Subject: Trailering a Kitfox
    Kitfoxkirk <aviateer@gmail.com> asks: "I trailered my Kitfox about 300 miles. When folded the wings back out, I noticed that from the flaperon vibrating on the horizontal stabilizer in the folded position, it wore the aerothane off clear to the fabric. Any suggestions on how to alleviate this in the future?" Mine is a Speedster that came with a Skystar factory trailer and brackets. The trailer is single axle with springs and a large toolbox. Two brackets go from each front spar to the landing gear brackets. Two go from each rear strut to the horizontal stabilizer. These secure and support the wings. I tie the outer flaperon weights together with a bungee. This keeps the flaperons immobile and clear of the horizontal stabilizer. I leave the stick forward, elevators down. I put foam pipe wrap over the rudder and secure it to the wing brackets with bungees, so that the rudder is turned fully to one side. The tail is supported by a bracket that holds the aircraft on also. So do the ramps, and a motorcycle tie on each landing gear. I only tow it a few miles, but could go indefinitely like that, as everything is secure and nothing moves. I have never covered the top, but would explore a cover held on with bungees with pads under grommets and hooks, angled out, or tied on with cloth or ropes, using bungees from each tie or rope to the landing gear brackets or trailer as a tensioner to keep the rope or cloth tie tight to avoid flapping.

    They are SPI pistons. I used them in my snowmachine with good results so I rolled the dice. I dont care what the seller says, such as "I have used them in aircraft for 14 yrs blah blah blah". If you feel like rolling the dice it's your butt and your plane, I just got through with a 2 yr rebuild on mine and I dont feel like rebuilding it again cause I went cheap on the pistons, but it is just my opinion and something I have observed first hand with my butt in the seat doing the test flights for my buddy. We put stock pistons in the hole and the ring gap was well within specs. The SPI rings were not even strong enough to spring out and hit the cylinder all the way around after a little under 3 hrs on them. They were fine when we first put them in and we did not run the EGTs high or overheat the engine. -------- DO NOT ARCHIVE Leonard Perry Soldotna AK Avid &quot;C&quot; / Mk IV 582 IVO IFA Full Lotus 1260 As done as any plane will ever be.... cause now the tinkeritis takes over. hander outer of humorless darwin awards Read this topic online here: http://forums.matronics.com/viewtopic.php?p=217883#217883
