The HERC JOV-3 was a two-seat tandem helicopter originally designed by Drago Jovanovich at the Helicopter Engineering Research Corporation (HERC). The helicopter first flew in 1948.[1]
When McCulloch Aircraft Corporation purchased HERC they improved the design for prospective military use and it became the McCulloch MC-4.
