Heran 20cc Model Airplane Engine by H. Heran, Czech Republic, 1981
This 20cc ‘open rocker’ model airplane engine was made from a cast aluminum crankcase, a machined aluminum head, and a machined steel cylinder. Unlike most model engines of the era this one utilizes a nylon back plate (with crankcase breather) and vibration dampening engine mounts. It is believed that only about 12 of these engines were manufactured and sold.
