Good post, like the history. I had a Jensen Das Stick, thought that was one of the first? Wished I still had it, probably collectible now. I had a fuel tank give me a fuel bath once, I learned to finish resin for all my kits and ARFs, no exception. It is well worth the added oz. or two to the plane and gives it more longevity. I drill a hole under the tank compartment so the fuel will drain out rather than carry back over the next bulkhead. The drain hole gives me fast warning that I got a problem especially an indication to stop refueling!
