Just to elaborate on HillerBee's contribution.
The Schweizer 300 was designed as a training helicopter. However the Hughes 269, its forerunner, was originally designed for the US Army as an LOH (Light Observation Helicopter).
In 1986, Schweizer acquired all rights to the helicopter from McDonnell Douglas, who purchased Hughes Helicopters in 1984. After Schweizer acquired the FAA Type Certificate, the helicopter was known for a short time as the Schweizer-Hughes 300C and then simply, the Schweizer 300C.
