That sounds like a two year penalty with regards to flying! Don't forget that fabric covered airplanes aren't exactly "stout", and they fly just fine. Just between you and me, I have about two square feet of lower wing that's pure mush because my right wheel pant got ripped off and stuffed into it when I landed 20 yards short of the runway on my second crank break. I've been flying it that way for nine months now, although I plan to fix it over the winter, if I can quit flying for long enough. It sounds like you have wings now. It's difficult to say without seeing it, but I'd be tempted to finish it and fly it. Now if you want a show plane (and it won't stay that way for long) and don't mind spending a few extra years on it, that may be the way to go. It's your plane and your decision, but a lot of heavy planes got that way for "extra peace of mind"... Mark Langford, Huntsville, AL mail: N56ML "at" hiwaay.net website: www.N56ML.com
