This is a vintage Sterling RIMFIRE high performance radio control model kit # FS 27. The model has a 56” wingspan, and wing area of 525 square inches. It can be powered by a .29 to .45 ci engine. All the pieces are there, and construction on the fuselage was started by me. I built a lot of model aircraft but never finished this one. I brought the kit to California from New York in 1976. I will ship the kit in second box, by UPS.
