I have been looking at older low cost fabric planes. I know about getting a prebuy and pay now or pay later when buying a low cost plane. Plus I will most likely just look and not buy anything. My question is about the fabric. In reality what is the life of the fabric? Most the ones I have looked at were recovered in the 70’s with either polyfiber or ceconite. Of course everyone claims the plane has been hangered since it has been recovered. Is one better than the other? Or is it time to recover either way? Anything else I should know?
