Some flexwings are rated on 17 Stone for the front seat.Quite a lot of the older flex's are at 16 Stone.The wing fabric will last quite along time.It depends how you treat it.Rigging and derigging wil affect its lifetime as will storage.Common is to be kept in a hangar although I have seen them left semi-rigged outdoor and constant UV can drasticly reduce its lifetime.
