I hope you Kolb guys in the area give Greg, the new owner great welcome into the fold. I will miss the little airplane. I had a lot of fun with it over the last couple years putting about 100 hours on it. I visited 22 different airports, several fly-ins, camp-outs, and pancake breakfasts. I even towed it to Oshkosh and flew it at the ultralight farm. I took dozens of friends for rides, introducing them to light sport flying. I learned about Rotax engines and how great they perform. The MKII is a tremendous bargain for fun flying and I would recommend it to anyone. I bought it to have something to fly until I finished my Pietenpol Aircamper, which I hope to have flying this fall, but I didn't think I would enjoy the little beast as much as I did. I will keep my web site on-line to share information about the MKII for others that may be interested. I'm not convinced that I won't be back in a Kolb somewhere in the future.

In case lowering the left flap isn't enough, it wasn't for me, the following might be of use. Regarding the size of the trim tab, I suggest the following, as done on my Mark III classic: - Find a suitable piece of aluminum, as thin as .016, about two feet long and roughly six inches wide. - At the edge of the long side, bend 2" by about 30 degrees. - Tape, (yes tape it, it doesn't need to be with 600 MPH stuff), to the underside of the right aileron, letting only the 2" protrude beyond the end of the aileron. - The tab is to face down, to push the aileron up, to push the right wing down, to compensate for the heavy left wing. - Now you can test fly and see the results. If too much/too little. change the tab. Just don't leave the tape on too long, like weeks, for it may pull the paint when removed. - Once you're happy with results, the real fun starts, making a final mount. - Center your tab to cover at least two "ribs". Mark precisely where they are on the tab. - Scallop your tab to form two fingers forward, for attachment to those narrow "rib" tubes. - Drill and cleco the tab to the rear spar of the aileron. Approximately 2" spacing. - Now, most precisely, mark the center line of the "ribs" at the end of the fingers. - Remove the tab and drill a 1/16" hole near the end of the fingers, on that centerline! - Deburr everything. - Re-attach the tab with clecos and check how precise those !/16" holes line up with the centerline of the "ribs" - If precise, now use the tab hole as a guide to drill a 1/16 hole into that narrow #$%^& rib.

Kolbers, Last year about this time I bought a Firestar 1 for a really good price, I thought. I wasn't thinking about registration when I bought it I was looking at ultralight class. I have since talk to the FAA and have been informed that the only way I can legally fly this plane is under part 103, which I am trying to do, but I don't know if I can get it under the 254lbs. It was never registered by previous owners that I know of so thats out, the one thing that I suggested that the FAA thought would be do-able is to find a registered firestar 1 that has a airworthiness certificate that has been damaged and use my plane to rebuild it. The sad thing is mine is in good flying shape now and I flew it about an hour and a half last summer. If anyone knows about a firestar 1 that fits the bill for a reasonable price please let me know. Meanwhile I am going to try to get in touch with previous owners to see if it was ever registered.

Hart" Subject: Kolb-List: The Rest of the Story Jerry, The following goes to show that when you want to find it, you can't, and then after you have owned up to the fact and reported it to the world, you find it. While repairing a FireFly corner wing brace down in the basement, I spied some folders on one of the work tables. Looked through them and found the brown envelope with the name on it. There were several telephone numbers on it, but when I reverse looked them up, non seemed to be valid. So I Googled machine shops in Dexter, Missouri and started calling. On the second call they knew about Bill Dinkins (The name I heard and spelled as Denkins). This fellow gave me his brother Ted's number in Dexter, and he gave me Bill's number (573) 421-4250. We had a nice talk. He has just retired. His plane has been in the shed for five years. It is in good shape, and he said he would be pulling it out this Spring and expects that after re plumbing the fuel system the 503 will start right up and he will be back in the air. He lives at 8805 cty road 412, Puxico, MO, which is about 20 miles next to you. I have completed making tubing splices for the broken wing braces on the FireFly. And, I have removed and modified the right wing brace. I hope to remount it tomorrow and then start on the left wing. Jack B.

All of this advice is good, but of course I didn't do it that way for my Firestar. I merely cut a piece of lexan long enough to fit over two ribs, put a bend in it, and rivet it onto the wing. Take it up in the air, if it is too much, take a pair of tin snips and trim it, take it up again, and keep trimming until it flies like you want it to hands off. The nice part about lexan is that it takes on the color of the paint that it is attached to, and you can see where to drill the holes. Keep in mind that I am more goal oriented than some others.

Greg, Many Firestars were never registered, but instead flown as ultralights whether or not they actually made the 254# limit, which I understand is just _barely_ possible if the plane has a 377 engine. Probably most ultralights are over 254#, and nobody is checking... a few pounds overweight is a lot less obvious than two seats or a large gas tank.
