Bud, Thanks for the info. I did call Sig and ordered another wing for about the price you quoted. I don't think that this will be a teriffic flyer, but wanted to build it with my old friend in mind. The key his wife gave me has only one sheet of plans. I was wondering if that was it. Since it has a foam wing, I thought that was probably it. I think my is is really old, since it doesn't really address the installation of radio gear very much. I would certainly like any info you could send me, I wonder if it might be easier if I gave you my email address ([email protected]) of my mailing address. When I talked to the folks at Sig, I was saddened to hear that if they don't sell about 25 to 50 kits a year that they discontinue making that model. Thanks again for you time. Chuck
