King Hi Al: Welcome to the Kolb List. Where in Asia do you live? Asia is a pretty big continent. TNK is a very small company. That means they have 4 full time employees, President, Donnie Sizemore; Parts and Sales, Travis Brown; Ken does fabrication; and Dennis is the welder. You were speaking with the welder because one of his secondary duties is to answer the phone if Travis and Donnie are not available. Why don't you give TNK another call and talk to the Pres? TNK is more than an airplane experience. They are more like family, once you join them. Don't think you can expect that type treatment from the larger airplane companies. I have flown the new MKIIIx.

Pushers are inherently noisy because the propeller is chopping disturbed air from over the wings. With a 2-blade, both blades are chopping at the same time, kinda doubling the noise produced, hence the advantage of a 3- blade is that only one blade is chopping the air. Another lesson learned is that shorter props, and hence less tip speed, are quieter. I was swinging 58 inch props which were much quieter than friends who put on 62 inch props. Warp drive props, I have since learned, are presumably okay for the Jabs, and hence a 3-blade setup is possible.

When I took it off to find out if I would get more power without it I also found that it made no more noise than It did with the muffler on. At least in side the cockpit it is no more noisy. I have never heard the noise from out side but I'm told that my straight pipe VW sounds considerably better on a over flight (I don't know if it is more quiet or just lower pitch) than a muffled Rotax. My first engine mount used the stock Kolb mount which allowed my redrive VW to move around quite a bit and was fairly quiet inside the cockpit. One day I even took my head sets off to see if I could fly without them.......I put them right back on. When I switched to the new lower custom engine mount the inside noise increased quite a bit. I currently fly with MP3 player headphones stuck in my ears under my noise canceling aviation headphones. I have tried stopping the noise with noise reducing foam in the gap seal and behind the cockpit with little benefit. I think the biggest noise source is the prop and engine vibrations. Select a prop with the lowest tip speed and use the softest vibration dampers (engine Mounts) you can get hold of. Stock Kolb vibration dampers are pretty good too bad I can't use them. Of course shorter props will produce less thrust and too soft a engine mount may allow the engine to twist out of alignment (not a good thing). My $.02 worth.

The owners have basically said "no ultralights". If I annoy the neighbors, I'm out. So.........I am hoping this combo will be quiet. (Kolb Twinstar / hks ) - as a matter of general interest, the twinstar with the hks, custom fuel tanks, twin facets, gascolator(it all adds up) minimal fairings, weighs 460 lbs. With a gross weight of 750, it's a one and a half person plane.

I recall the Lockheed 'quiet plane' they developed for Vietnam use. It was astonishingly quiet, mainly due to a huge slow-turning tractor prop on a shaft above the fuselage. Kolbs can't do that; no help there. But the exhaust was fairly large in diameter and aimed upward. I read that one Kolb installation had the exhausts aimed up and FORWARD. I'd think that would produce too much back-pressure, but if it works? They've done a lot of things with 'tuned exhausts' on VW dune buggies -- that might be close enough to have some practicality for kolbs .

That 4 blade powerfin is waay too much prop for the HKS unless you will be pushing a trike. What kind of Kolb are you putting it on?

It didn't have the strongest aileron response either, tho it had the lightest controls of any airplane I've ever flown. I too was advised about the additional loads that could have been imposed on the wing and ailerons themselves if the spades had been added. So I never did actually tr it. My titan has spades on the ailerons but the wing, aileron and attach hinges are noticeably significantly thicker, stronger and etc. The airfoil is different as well so it's just got loads of aileron and can handle spades. The kolb wings still strike me as pretty strong, but probably still getting close to a limit with the extra deflection. I resolved the issue by not flying my FS II in bad weather and just letting the brave guys call me names.... It was more fun to fly in smooth morning or evening conditions anyway. In fact that's still how I fly and I still get called names ;).....
