In order to introduce a small turbine powered airplane, Soloy first produced their own certified turbo prop version of the Rolls-Royce 250 engine previously used in the helicopter conversion. The Soloy Turbine Pac was installed in the Cessna 206 then later the Cessna 207. The Soloy Turbine Pac enhanced operational capabilities for these Cessna aircraft especially those on floats or used for sky diving operations. In addition, Soloy has developed many improvements for mature designs using original Soloy systems or power plants that were not available to the original aircraft manufacturer.
The second generation turbine powered Cessna 206H MKII utilizes the 450 horsepower Rolls-Royce 250-B17F/2 engine.
The 8 place Cessna 207 conversion utilizes the 418 horsepower Soloy Turbine Pac with the Rolls-Royce 250-C20S turboshaft engine.
