269C "Model 300C"
The 300C is powered by a 190 hp (141 kW) Lycoming HIO-360-D1A and has a larger diameter main rotor (26 ft 10 in compared to 25 ft 4 in).
The larger rotor and engine gives it a 45% performance increase over previous 269-series models.
Hughes and Schweizer both marketed the 269C as the Model 300C.
300CQ
The Sky Knight is a purpose-built 300C for urban police helicopter patrols with a muffler and other noise attenuating materials and design changes to reduce the helicopter's noise signature by 75%.

300CB
The 300CB is the first pure production of the 300 by Schweizer and is powered by a Textron Lycoming HO-360-C1A, 180 hp engine.
The 300CB first flew on 28 May 1993, and was certified by the FAA in August 1995.
The 300CB can be reconfigured from a two-seat cockpit to a three-seat configuration.
While it is still suited for utility and special missions, this aircraft was designed for helicopter training.

300CBi
A fuel injected version of the 300CB that alleviates carburetor icing concerns in colder temperatures.
The 300CBi also includes overspeed protection and automatic rotor engagement during startup, as well as a low rotor RPM warning system.
