What Was It?
Back in the 50's my brother and I got a 1/2A u-control plane kit that included an engine fitted with speed control...the first I had seen. The engine was fitted with a small rubber bellows, and a plastic tube ran out with the control lines. It terminated in a rubber bulb, which could be squeezed to operate a venturi clapper and an exhaust throttle.
The plane itself had a profile fuselage and it had tricycle gear. As I recall, the outline was somewhat similar to a T-28.
The engine started and ran well, and it was fun to fly. The only problem was that the plastic tubing had a huge amount of drag, causing it to belly out.
Can anyone tell me what this was? The only ones I ever saw were those belonging to my brother and me. I'm guessing that they weren't on the market for long, and I wish I had kept mine, darn it!
