The story

Aircraft Engine

One of McCulloch Aircraft Corporation's engine designs was the McCulloch O-100-1 (model 4318A). This engine was a single-ignition, 2-stroke, 72 hp target drone engine.

This small McCulloch 0-100-1 engine was used in drone aircraft like the Radioplane Model RP-15 (OQ-6) and the MQM 33 (Q-19).

Helicopter

The McCulloch Aircraft Corporation acquired Helicopter Engineering Research Corp in 1951. It manufactured two innovative helicopter designs – the tandem-rotor MC-4 and the J-2 autogyro.

Rights to the twin-rotor MC-4 was sold back to the original designer, Drago Jovanovich, in 1957. Rights to the J-2 autogyro were sold to Aero Resources (Gardena, California) in 1974.
