Thanks Brad. The wing is as you described. It is one of the particular film coverings over balsa.The ailerons themselves seem to simply be balsa with a paper glued over to give it that ribbed look of the real cessna.

Here are some more thoughts. I looked at this thing again this morning on my way out the door. The ailerons seem to be straight when I look down the trailing edge. The center section of the trailing edge of the wing seems to be the offending section. At least one side is definitely twisted (or curved down actually). This I may or may not be able to fix with a hair dyer. That is, I noticed that if I bent it straight, it put wrinkles in the skin. So I am guessing I can heat those out and it may actually hold the edge of the wing straight(er). And the ailerons also seemed to be pretty flat when they were lying on the work surface before I glued them. But I didn't go looking for warp either.

The thing that seems to be the biggest problem is the whole model seems to be unsquare. I imaging the wing and tail have to be square, but there really doesn't seem to be any good starting point. That is, the saddle seems to be crooked to the frame, the saddle and frame seem to be crooked to tail, and so on.

Like I said, I am going to call Wattage today and see if they can offer any help. I am going to try all the things you suggested (especially checking to see if the ailerons will work as you suggested). Then, I am not sure what I will do. One step at a time I guess.

I too wish I had access to you to check this thing out. That would be a really big help I'm sure. At least i would know if I am supposed to keep going with this thing, or if it will end up being a $70 pile of scrap wood and small parts!!

Thanks again for the suggestions!

Andy
