Dago Red
I know not everyone checks the market place here, but I saw this nice Dago with engine listed for a very reasonable price. Looks like its one of Lyles trademark paint jobs, not really my color choices, but very nicely done.
Just thought I would post it, if anyone is interested. I don't know the seller, or anything else about this plane, just thought it looked like a good deal on a nice plane for someone maybe interested in getting into this, or looking for a back up.

RE: Dago Red
That's Dewey Davenport's airplane out of Ohio.. I remember the plane from the NATS 99.. I believe it had a twist in the wing, but it was fixed at the Nats.. It was a fast airplane and with the right Pilot can compete with anyone...

Well I have heard by those at the nats say the wing was straightened by heating and then twisting it the opposite direction.
I'll take a new one myself!

RE: Dago Red
It is really not that unusual for a composite wing to warp slightly over time. Even a small twist in a long Q40 wing will cause problems at the speeds these fly.
Heating it, and twisting is not as awfull as it sounds.
Here is an excerpt off of Darrol Cady's site (www.darrolcady.com) which explains the process.
Straight Racing wings
We used to straighten our build up wings in Formula One. The methods we used were much more difficult than we have a need to do today. Diagonal cut wings epoxied together was one way to do it for a very bad wing. We used to also cut the aileron line from where the ailerons ended to the tip. Then we would bend it and glue it in a new position to compensate for the twisted wing. We only did this with the worst of the warped wings. This was just prior to throwing them away and building a new one. Building a new one was common also.
Now, with the composite wings, there is no excuse for not having a straight wing, no matter how much of a twist there is in a wing. I had one wing that had so much of a twist in it that full aileron trim would not make it fly level. By doing what I am explaining, the wing was straightened to the point that there was no aileron deflection for level flight. In order for an airplane to be properly trimmed, there should not be any aileron deflection at all at neutral.
The first step is to fly the airplane and leave the aileron trim where the airplane needed it to fly with the wings level. Note which aileron is up. That is the wing tip to moved. By experience, I have found that if you move that wing tip to where the aileron and the fixed part of the wing tip on the outside portion of the wing is in line, it is very close to where you want to be. Moving it is easy.
Bolt the wing on the fuse and leave the radio on with the aileron trim in the position that it was in for level flight. Get someone to hold the airplane solid on a table with the wing we are going to repair off the edge of the table. I have found that the easiest place to heat and move the wing is at the aileron cut at the outside end of the aileron. Using a monocote heat gun, I heat about a 6" area from the trailing edge to the leading edge on both the top and bottom of the wing. If the temperature is correct, it should be hot to your touch, but not hot enough to bubble the paint. Heat it in several passes over the area instead of trying to do it in one pass. You must heat the top and bottom before you twist it to the proper angle. The heat must go deep in the wing skin, not just the surface to be able to move the wing.
Once the wing is heated, take the tip in your hand and hold it at where you want it plus a little. Now, while holding it in position, rub the heated area of the wing with a wet towel to take the heat out of the skin and to set the new shape of the wing. Remember the goal is to align the outboard aileron with the new wing shape with the aileron in the new flying position. You may have to repeat the process several times to get it where you want it after it has cooled. When it is where you want it, it is time for the next step.
Now you will have a wing that the aileron center and tip does not match the wing. We use the same method to straighten the ailerons. With the radio holding the center of the aileron at the neutral position, heat and bend the aileron to match the new position of the straightened wing. Now remove the wing and mechanically center the other aileron to match the wing. Next time you fly the airplane, the ailerons will be perfectly aligned with the wing and in neutral flying position. If not, you may have to repeat the process. Once I have completed this, the wings have kept their shape. The heat of the sun does not seem to affect the changes you have made.
This process is simple, and it has taken me longer to explain it than do it… Do not be afraid to try it, it works well.
