I have the remains of an abandoned pastime-- Scratch Building Radio Control Airplanes/Sailplane. All the products are of a 1980's vintage and consists of 6 airplanes/sailplanes, their plans/sketches, a large assortment of building supplies and parts, flightline kits and structure jigs. All the servos/electronics and engines have actually been eliminated, but the electronic devices would not probably not presently be usable. The entire lot is for sale for $175 OBO and will not be parted out.
Scratch structure is apparently not in vogue, however was a most enjoyable pastime at the time.
