Just found your post while searching for Jack Stafford website. I wish I had known they were going out of business I would have bought kits and parts. I built a Chipmunk from scratch using the 1968 MAN plans enlarged from the magazine. The toughest model I had ever built, that trick rudder/tailwheel assembly was crazy, but it does look very clean. I also used the heavier pink foam for my cores. And made the mold for the cowl, which came out o.k but not exactly as I had hoped.
