With no speed control, this engine would have been used before the advent of radio control on U-control or free flight aircraft that ran only at full speed until the fuel was exhausted. The position of the piston mounted below the shaft to keep a low profile in model aircraft uses an unusual mechanism to transfer the piston’s motion into rotation of the shaft above.
The model engine is on loan from Daniel “Buzz” Brunkow. Mr. Brunkow has a large engine collection and is also a builder of engines and fine wooden models. Several unusual pieces from his collection are currently on display at the Miniature Engineering Craftsmanship Museum in Carlsbad, CA. Mr. Brunkow has also contributed a model wooden Cushman scooter and Chris-Craft Cobra for display.
