I knew Norm back in 1970-73. His best airplane was the Mach I. He won the Nats with it. We flew at a field in Elk Grove, Illinois. He and Gary Leonard were partners in Wing Mfg., making foam wing cores and plastic parts for an assortment of models. Norm's Mach I was later kitted by Midwest Models. I believe you can still get plans from Airage.
