The Geo/Suzuki one litre engine weighs a little more than a Rotax 582, it produces 62 HP normally aspirated but with a better, flatter torque curve. Both bolt on gearbox and cog belt redrives and all other aircraft conversion parts are available for very reasonable cost. Turbo versions are available also. Gearbox type redrives for around US$1750- The Geo/Suzuki engine uses about half the fuel that the two stroke engines use. The 1.3 litre four cylinder Suzuki engine beats the Rotax 912 in power and weight, again both gearbox and belt type redrives are available. All those advantages plus flying engines with the hours up to prove them and last but not lease, far, far cheaper than a Rotax. There is a Yahoo group about these fantastic little engines used in aircraft, it is a very active and helpful group. One person on the group has over 1000 hours on one installation. http://groups.yahoo.com/group/FlyGeo_uncensored __________________________________ ________________________________ Message 4 _____________________________________ Time: 03:41:31 AM PST US From: "Fox5flyer" Subject: Re: Kitfox-List: Tailwheel Steering springs --> Kitfox-List message posted by: "Fox5flyer" Correct.

What other pros and cons are they for gsc vs. WARP or IVO ? Has anyone actually charted these numbers? Looking back, I think I picked up a good honest 5+ MPH when I went from the GSC to the Warp. Was around 80-85 MPH now 85-90 MPH. A con to the GSC is the possibility of crushing the wooden hubs by overtorqueing. I think that is what happened to my GSC. It was used so I don't know what the other owner might have done. A pro for the Warp is the ability to repair in case of a minor prop strike. This also happened to me. Warp fixed my blades for around $80. I think a GSC would have splintered. Another pro for the Warp is, it's easier to adjust the blades. They adjust the same way as the GSC but they turn easier in their hubs. My GSC hubs became a bit oblong in shape (possible overtorqueing or not). When you tighten the GSC, they wanted to turn a bit in the hub and go back to their normal set. I have no experience with the Ivo. There was a time (way back) when the Warp appeared to be the prop of choice over Ivo. Don't know if this has changed or not. The above 80-90 MPH numbers are based of several factors and it's hard to compare one Kitfox to another. Pitch, jetting, drag, props are all different. I once got around 95 MPH in cruise. However, the prop was way overpitched and not good for the engine. I bet these comments will get me a blast. personal opinion/observation only Don Smythe Classic IV w/ 582 ________________________________ Message 10 ____________________________________ Time: 07:35:29 AM PST US From: David James Subject: Re: Kitfox-List: Prop tape --> Kitfox-List message posted by: David James --- kitfox@gto.net wrote: > --> Kitfox-List message posted by: kitfox@gto.net > > Don, > > What kind of performance numbers do you get with the warp prop? > I have a gsc wooden one and it seems pretty decent.

It gives more thrust and everyone tells me it's a lot quieter. Similar price to a Warp Drive too. On another group a bloke compared one of the Russian/Ukrain props (Again a beautiful curved shape with twist) against an Ivo and his actual numbers before and after were far better with the Russian prop. I dont know the price of the russian props though. The Warp and Ivo props are like a piece of junk wood compared to those "Real" props. One other thing about the Bolly prop, the blades fit Warp drive hubs so if you have a WD hub you can save some money. I dont know if the Russian/Ukrain props fit the Warp Drive hub though. __________________________________ Stay connected, organized, and protected.

A glass of wine with a good meal, never more. But my father told us, when we were kids, that - as an instructor on the C-119 Flying Boxcar, he used to put a glass of water on the glareshield and ask the trainee to land without spilling one drop. Later, looking at the slooped glareshield of the C-119, I wondered if my father (who passed away in 1986) was just making it up. Or maybe it was on the central console and I mixed it up. Has anyone heard of an instructor doing that in any plane?

I have been told that my wooden prop doesn't like too much flying in the rain. At near the speed of the sound, water will "sandblast" the prop. However, I was told that if the rain was not too dense and that I kept a relatively low RPM, I could get away with it. I have no intention to fly in rain. First, it reduces dramatically the visibility. Second, my Kitfox is far from being watertight. But, if I am up there and a light rain shower comes on my path, should I navigate around it, or just take it but carefully? How bad could I damage my prop? I have a fixed pitch two-bladed Jabiru prop that has some kind of black rubber leading edge, otherwise, varnished.

Also see a lot of engine cowl tops painted flat black. However, this does bring up a thought. Painting propellers can throw off the balance. I made a homemade balancer way back and tested my GSC. I ended up spraying a little clear Polyurethane on one blade to help in balancing. I was surprised to see it make a difference. This might be apples and oranges but every little bit helps.

Just make sure you are using the correct type hose. On the 912 the oil lines are suction hoses, not pressure hoses. The hose must not collapses in suction when hot. Skystar and Rotax really do know what they are doing. On the fuel line I think it is very important to route them so if you have a exhaust break anywhere it will not burn the hose off. Firesleave the fuel line in addition to correct routing. Firesleave kept me from becoming a burning lawn dart when an exhaust broke right next to a fuel line. The legal requirements are not like a certified plane. You can use hardware bolts if you are craze enough to do it. I use a lot of race car items from www.jegs.com because it is good stuff and it cost less. AN not required.

I think a lot of these FBO's, A&P's, long time Pilots that have never been involved in Exp aircraft just simply apply what they have seen on Certified aircraft. The use of good AN hardware is certainly advised. I have another opinion on the barbed fittings. Once a hose is pushed onto a barb fitting, it "almost" doesn't even need a clamp (seals good). Also, "I believe" a hose should be pushed onto a barbed fitting only once. When it gets removed for any reason, it tends to "tear" the inside of the hose causing a good spot for small rubber particles to be torn loose and end up in the Carb. So, if you pull one off for any reason, either trim the end to expose new hose or replace it. If you have a hose that needs disconnecting regularly, use the AN type.

I think the paint is to cover up flaws in the prop. I don't think the latter is an accurate statement. I found this in the West Systems page. Consider that they are largely in the boating industry where is lots of sun and they if anyone would be up to date on UV exposure. Quote: "This hardener was especially developed for use with WEST SYSTEM Brand 105 Resin in coating applications where an exceptionally clear, moisture-resistant, natural wood finish is desired. Cures to a light amber color, similar to traditional spar varnishes. An ultraviolet inhibiting additive improves the resistance of a WEST SYSTEM 105/207 mixture to sunlight, but the cured epoxy surface will still require the additional protection of a quality UV-filtering varnish. 207 is designed to self level for smooth finishes, and to wet-out and bond fabrics. Although it provides good physical properties for general bonding applications, it is more difficult to thicken and less cost effective for this purpose than 205 or 206 Hardeners. It's also used for laminating veneers where bleed through at joints may be exposed to sunlight."

The use of good AN hardware is certainly advised. I have another opinion on the barbed fittings. Once a hose is pushed onto a barb fitting, it "almost" doesn't even need a clamp (seals good). Also, "I believe" a hose should be pushed onto a barbed fitting only once. When it gets removed for any reason, it tends to "tear" the inside of the hose causing a good spot for small rubber particles to be torn loose and end up in the Carb. So, if you pull one off for any reason, either trim the end to expose new hose or replace it. If you have a hose that needs disconnecting regularly, use the AN type.

But they are relatively easy to repair. With a protective leading edge they will wear much less. It sound like your prop has a vey effective leading edge protection. Flying in the rain will not ruin the prop in a single flight unless you hit hail. It will slowly lower its efficiency.

I have used clear epoxy from West Products as a base finish for teak on my sailboat, and all literature warns that I must use several top coats of other materials with high UV protection to protect the epoxy from UV. Jim Crowder ________________________________ Message 38 ____________________________________ Time: 11:00:46 PM PST US From: kurt schrader Subject: Re: Kitfox-List: Jab report --> Kitfox-List message posted by: kurt schrader Hi Michel, *My last entry on the list until I return. First to your other question - if you see rain (with your wooden prop) you should go around it. If you can't go around it, don't panic. Reduce your RPM and slow cruise out of the rain. Check your prop when you land. You might ask your prop manufacturer if they supply a leading edge protective tape for your prop. Some do. It would decrease the likelyhood of wear. If you catch the wear fast enough, you change tapes, not props. Now to your {?} in a bubble. Yes, the free floating door would respond to the dynamic pressure and seek to find the neutral point. But you could very well get flutter from it. Not good. This would be another reason to use an opening spring in my opinion. You could use your X-Plane simulator to "see" the pressure around your cowl, right? The curving bottom of the cowl produces low pressure like the upper part of the wing, but this may be mostly gone by the rear of the cowl like at the trailing edge of the wing. I do not believe that you need 4 times the exit as cowl entry for your engine. Where 1.5 to 1 might be normal, you may find that 2 to 1 would be enough for you. With your current door, do you close off the exit more than 2 to 1 when fully closed? Old VW's had a metal bellows that expanded with heat and opened the cooling doors inside the fan housing of their air cooled engines. This was the VW air cooled "thermostat". By memory, I recall that it was a fairly powerful bellows, but that it weighed a bit too. Anyone have any recent experience with these and know if they would be suitable for controlling cowl doors? I do not remember their temp range, actuation distance, weight, or force level. But if not too heavy, they might make an affordable auto cowl door controller. Kurt S.
