"Global Warming" is best described by the Spanish words .....Eltoro Poo Poo !... I can usually sum up how severe the winter has been by how many times my snow blower broke down....many , many this year and it is now in my shop after both wheels just fell off....no joke...the axle broke in half.

The distance from the pulse pump exceeds recommendations but apparently works. If you were to use this system and fold the wings regularly, it might present some problems. I don't think I'd like to repeatedly connect the fuel lines.....to much room for leaks and loose fittings. Maybe use this location to haul "spare" gas...no plumbing, just fuel to refill with at remote locations. Or.....how about mounting one of these footballs on either side of the engine over the center gap seal........make it look like a little mini-Warthog. Then hang a couple Sidewinders on each strut.....a 50 cal. between the gear legs....new coat of Poly-Tone camo.... I gotta quit this stuff.....been watchin' too much MSNBC..... Denny, we aren't too far apart.....maybe this summer we could get together. You aren't too far from Dennis Souder. Ever run into him? Mike in WV do not archive

Not sure if it will help but those numbers are: UL94HB 5012043 I am assuming the 425 is the PSI working pressure so anything that you can find that meets or exceeds what Matco supplies should work fine.

    Subject: Sun n fun
    --> Kolb-List message posted by: Timandjan@aol.com Lots of talk earlier about sun in fun. I plan to fly in commercially to Tampa, rent a car and hit the show. Planing to fly in Wed and leave Saturday. I plan to get a room somewhere, or camp. Is anybody doing the same and might want to get together. Is anybody planning to camp at a place where I might join in. I can bring a tent etc. Just use a corner of the camp site. Last year I went for a few days in my RV, had to pay for the entire week to camp and get a parking pass, no biggy, but not worth it for me to only be there for a few day this year. (you can't just camp for a few nights like at Oshkosh, have to pay for the entire week) SInce I plan to get a car, if you flew in, maybe I could use your pass to park and in return I would be glad to shuttle around for food, restaurants etc. I usually go from sunrise to sunset, only need a place to sleep and shower. Anybody interested??? Let me know. Tim in VA. DO NOT ARCHIVE

Thanks! Kirk thrust should be directly forwards in the cruise attitude, for best cruise performance, or in the climb attitude for best climb performance. ussually closer to cruise attitude is chosen, which will be a couple, maybe 5 degrees aoa on the wing. so slightly below the level of the bottom of the wing.

    --> Kolb-List message posted by: "Peter Volum" <peterv@etsmiami.com> This could be worth pursuing Richard... The guy who sells starters for Rotax Engines (GPL) also sells Rotax engines for Hovercrafts (including the 912, although admittedly not the 912UL). If the parts for non-UL 912's really are the same ones as those for 912UL's, and if the only difference is $$$, then for non-critical components one may well be able to save a considerable amount of dough. I would still feel better about buying critical components from a distributor of the aviation series of engines just in case there is a difference though.

Kirk =============================== Good question, and one that I have been pondering over for a while. Essentially the optimum thrust line is somewhere between the center of gravity of the Kolb on its longtitudenal axis and its center of drag. Eye balling it would place the prop hub somehwere, where the lower back of your neck would be with the engine mounted. That would call for a real small prop and I would guess about 5 blades for an M3X. I think the Verner is the only one that I was told where you can move the reduction unit either up or down. What do you have in mind?

    Subject: Thrust line
    --> Kolb-List message posted by: "Christopher Armstrong" <cen33475@CenturyTel.net> Essentially the optimum thrust line is somewhere between the center of gravity of the Kolb on its longtitudenal axis and its center of drag. thrust overcomes drag, so if you do not want to have a pitch change with throttle change then you want the thrust line to go through the center of drag. On Kolbs that have very high thrust lines you need to understand that at low throttle settings the prop has almost as much drag as the plane. what this means is that the center of drag is moving up and down with throttle setting, exagerating the pitch effect of just changing power. The plane rotates about its center of gravity, so sending the thrust line through the cg would result in no change of pitch with change in thrust only if you were also flying directly in that direction, and there was no change in drag with power setting. You never would be flying in that direction in a kolb, you would be stalled and falling in that direction! if your flying at a reasonable angle of attack and the prop disk was pointed down enough to hit the cg the prop disk would be canted to the airflow significantly, creating a pfactor and a down force at the prop, which would cause a nose up pitching moment, because the thrust line would not be in line with the normal to the prop disk, cause the prop disk is at an angle of attack. so you you would actually line up the thrust line with the cg not the normal (perpendicular) to the prop disk, they are not the same, which is why most engines are mounted on planes at weird angles. usually 1 to 3 degrees to the right and a degree or 2 down. This is also why Rutan's boomerang is actually more symetrical airplane then a standard twn even though it looks asymetrical. Props dont generate thrust from the center of the prop hub unless they are at zero aoa. in a climb you have the prop disk at an aoa and the thrust is coming from 8 or more inches off center. when you take the details like that into account you design an airplane that looks assymetric but is really symetrical aerodynamically. opps, rambled on and on again, probably causing more confusion then clarity! topher

At the risk of sounding self centered - this is about what I want :) For now I want to know more about performance of the wood props and dip into the collective consciousness of the group to find past experience.

I will be installing this on a Jabiru with no reduction. My calculations call for a 60 30. Jabi suggests a 58 44 using a rule of thumb of 1" diameter = 2 degrees pitch we can see that my calculations are off a bit to Jabiru. I will probably go with the 60 " prop. The main difference is that I used a top speed of 85. I probably should have substituted a higher number in there. How fast can a mk 111 go? >Topher > >

    Subject: IVOPROP Pitch
    --> Kolb-List message posted by: ALLENB007@aol.com Kolbers, Can you tell me which way to turn the bolt on a Kolb pusher standing behind the plane and facing the prop. Is it clockwise or counterclockwise to ADD pitch? Thanks in advance for your reply/replies, Allen

    Subject: Re: IVOPROP Pitch
    --> Kolb-List message posted by: "Beauford Tuton" <beauford@tampabay.rr.com> Think of the bolt as the prop control knob on a cockpit pedestal... screw the bolt in (forward toward the front of the plane) to increase RPM, screw it out (pull it back toward the tail) to decrease RPM... There is a tad of free play slop in mine before it actually engages the cams, but you can feel it when it begins to actually touch and start having effect... Good Luck...

    --> Kolb-List message posted by: "Larry Bourne" <biglar@gogittum.com> Do not Archive. Can anyone out there get me a list of STC's for that old 1941 Piper J-5 that I'm still trying to buy ?? A minor (??) problem has arisen. Please reply off List. To keep this Kolb related, Vamoose is covered, and now I gotta catch up and finish rivetting the ailerons & flaps onto the wings, then finish getting the engine back running. Almost time ! ! ! Lar.
