One of my club members a former pattern flier has had this taking up space in his basement for the last 17 years. A semi kit for Mike McConvilles 60 sized desire. Foam cores, fiberglass and plans. One of the early and successful turnaround designs.
This brought back some memories as I saw the plane fly at the Nats probably 1991 and talked Mike into sending me a couple of sets of Fiberglass and photocopied hand drawn plans. I had to cut the cores myself. I built 2 of them. In the next year or two the YS 120 4C planes started to dominate the pattern scene. He did design a larger 120 version.
The cores and FG parts were bought from RC city (invoice still on box) They were $50 each. The plans from Flying Models plans service. Not sure of the price.
