Any affect on yaw with only one door removed? I also noticed at the end of the video you mentioned that rear cylinders (CHT I presume) are running about 320F and your oil temp before installing the oil cooler was in the 220-230F at 75F OAT. This summer, is the first time my oil temps got into the yellow area (>212F), so I was considering adding an oil cooler but probably won't since the heat wave seems to have passed. Yesterday, with now normal high temps in low 80s, I was seeing 195-200F oil temps and 270-280 CHTs. FWIW, my CHTs rarely get to 300F except in extended climb at full throttle. I'm wondering why so much difference. My engine is serial #1574 (solid lifter). Is yours a solid lifter or hydraulic lifter engine. I've heard that the hydraulic lifter engines tend to run a bit hotter. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 Truth is what stands the test of experience. - Albert Einstein Read this topic online here: http://forums.matronics.com/viewtopic.php?p=347648#347648 ________________________________ Message 3 _____________________________________ Time: 05:44:36 AM PST US From: robert bean Subject: Re: Kolb-List: Re: No N number For sure, that is not a "buy it and fly it" airplane. -which is the smartest way to get an experimental, just write a check for a purty one.

Boyd, Sorry if you felt that I was directing my request for no shooting at you. When I first posted the warning about losing the A/W certificate if an E-LSA's registration was allowed to lapse on the Rotax engine list, I got some really abusive private emails for my trouble. There are some real jerks out there who run Rotax engines. I'll do the best I can to explain as I understand it. Buying a type certificated plane, a Cessna or a Mooney, is a lot like buying a car. You buy the plane and the dealer files the paper work to transfer the registration to you. The A/W certificate work had been done by the factory. Just like a car, although with a car you get paperwork that says your car meets all the Federal regulations about safety, but no single certificate that has to be carried in the car (a Road Worthiness certificate, if you will). Now imagine if cars were like experimental aircraft. You would go to the dealer and buy the car, then file to register it. Before you could drive it away, a DMV representative would have to come out, inspect it, examine all that safety paperwork, make sure the VIN number was stamped on the car's chassis, and then issue the pink slip. Now comes re-registration. E-LSA, the FAA's version of the red-headed step child, is the only category of aircraft that I know of that is affected in this way. You let the registration lapse and it gets cancelled. You want to re-register but the form that has to be filed with the 8050-1, "Aircraft Registration Application" (the three parter), the 8050-88A , "AFFIDAVIT OF OWNERSHIP" has been revised since February 1st, 2008. In the declaration section it no longer has the box to check that said, basically, this is a previously flying aircraft (Fat Ultralight) that I built and flew quasi-legally under the FAR 103 training exemption. Now, there are only two boxes, one for S-LSA and one for E-LSA and both require that the aircraft "will meet all applicable consensus standards" either under FAR 21.190 for box 1 (S-LSA) or FAR 21.191 i(2) for box 2 (E-LSA). This means that you must have the Certificate of Compliance that comes with your aircraft or your kit, respectively. Obviously we "Fat Ultralight" owners don't have that certificate and can't get one by any reasonable means. Without it, now, you can't re-register the aircraft. Since we register to get an A/W cert, no registration, no A/W cert.

The builder did modify the entrance by trial and error placement and size of the aluminum plates in the lower part of the duct entrance. He said that getting this part right is the secret to getting all the cylinders cooling well. Next time I am at the hangar (late this week probably) I'll take some measurements and photos of how mine is set up and post them. I'm also curious about your EGTs. I have installed only one and it has been running too cool at cruise and too hot at WOT climb so I ordered several leaner cruise jets (needle jet) and several richer main jets and installed them. Did not make much difference in cruise but did lower EGTs a bit on climb. My carb still has the original Bing jet needle, not the newer Jabiru designed one. What EGTs are you seeing and is your carb stock?

Both are quick solutions to a real problem I am impressed. Rick, since Lowe's sells 1 x 2 x 2 foot oak boards for $2.24, I see no excuse for using anything other than the hardwood you suggest. Scrap oak flooring you may have lying around is ideal too. This discussion leads me to think of the much more common task of replacing a landing gear leg and matching existing holes in the fuselage socket. Here, I think that either of your solutions described here should work great and it should be mentioned in this forum. -------- Jerry King Read this topic online here: http://forums.matronics.com/viewtopic.php?p=347661#347661 ________________________________ Message 10 ____________________________________ Time: 07:12:05 AM PST US Subject: Kolb-List: Re: W&B From: "Ralph B" tkben002 > Thanks Ralph for posting your numbers.

From: "Mystic" john tempest you tube video..... the video was interesting..would like to know camera you were using and mount. Hi Jim, My Camera is a Kodak Playsport that was a gift from sister to take on kayaking trips. It's waterproof and works great for that. It wasn't until I uploaded the first videos and watched them on my computer that I realized what a true gem this little thing is. The clips you see on you tube do not do this thing justice. The picture quality is amazing. My only complaint was short battery life, but I found some cheap spares on E-bay,(that were actaully higher capacity than the Kodak supplied one) so it's no issue now. Being a proletarian, I used a very simple/low tech approach to mounting my camera (cheap). I drilled 1/4 inch hole in bottom of tail boom, just forward of tailwheel rod. I used long tongs to drop in a 1/4 inch thumb screw with small washer so that I had about a half inch of threads poking out the bottom. I then used a nylon nut to secure the thumb screw in tight. The nylon nut allows me to screw my camera (in a up-side-down attitude) on the thumb screw, snug it up tight and face it straight without damaging threads inside camera.(which are plastic) I then use the camera tether (wrist strap) with a zip-tie looped thru the tailwheel gap to put a rear pull on the camera which points it down a little more and stiffens it up. Once I upload the footage, I use quicktime pro to invert the video to right-side-up. I'm sure there are other, probably better ways to do it. And ones that don't involve poking a hole in your plane. But I'll bet it can't be done any cheaper.

At any power setting above 70% they want it richer, in the range of 1184F - 1256F. Mine runs up to over 1300F during climb at 55 mph and WOT but decreases to around 1250 or so if I increase the climb airspeed to 60 mph or above. That is good enough for me since 60 mph is Vy in my Slingshot. At cruise mine is running around 1225F or so, even with the leaner needle jet per Jabiru's recommendation. I think I need the Jabiru jet needle to get it right. Of course, it could be the our props that make the difference. Mine is a good bit longer than yours (64"). My plugs are a little on the dark side of ideal which more or less confirms the EGT readings. Pete Krotje of Jabiru USA says you can bias the mixture a bit from one side to the other by tilting the carb 10-15 degrees or so to one side but I don't recall which way he says to tilt it for the bias you want. I have only one EGT probe and 3 CHTs. My CHTs all run within 20 degrees of each other under most all conditions.
