The Cessna U-3A Blue Canoe kit is a tiny little thing modified out of an exceedingly rare (extinct?) Aurora 1/72 kit; a very nicely done late 50's/early 60's vintage kit. It was issued as a civilian Cessna 310, had recessed civil N-number; to be filled, and had no landing gear, being issued with the dinky little display stand of the era. But most surface detail was RECESSED. Adding a landing gear scratched from spares box wheels, sprue, and sheet stock gear doors turned out to be surprisingly easy. Masking the white paint to have a white surround on the natl insignia was a challenge, but the hardest part was getting enough weight in its pointy little nose to make it stand on three wheels. To this day, it does that barely. Breath on it and it sits on its tail. The white United States Air Force decals not easy to find came from Bob Leavitt's decal spares, as did the blue tail serials. As I recall I put individual numbers together to have an authentic S/N.
This model currently resides in the big 1/72nd Gen Scott chapter collection at the Robins museum.
