Well, first off, the latest issue of one of the magazines just did a review of the Seagull Spacewalker. If you have it, it mentioned that very problem. If you don't, I can find it and try to paraphrase it. I believe the reviewer offered a solution, but my memory is garbage!

Last week at our local club meeting, that Decathalon was the raffle prize. The guy that won it opened it up and went through it right there, it was very impressive. I can't speak to the hardware / tank quality, etc., but the building and covering was BEAUTIFUL. Keep posting your progress with maybe some pictures, and maybe some flight reports?
