Video: STC granted for reversing option on MT props for Cessnas

Bloomer, Wis. — Flight Resource, a distributer of MT Composite propellers, has acquired an STC for a reversing option for the MT Composite two or three blade propeller for Cessna aircraft.

The system utilizes a two stage hydraulic governor and a dual piston propeller hub to allow a piston engine aircraft to have a full function reversing option similar to turbo propeller aircraft, company officials explain.

Flight Resource’s Cessna STC approves the installation of the 83-inch two or three blade MT Composite propeller to all Cessna 180, 182, 185, (T)206, (T)207, or (T)210 aircraft with any version of TCM -470, -520 or -550 engines.

The MT reverse system allows for enhanced maneuvering of seaplanes never before possible and effective braking for ski planes, company officials note.

The MT reversing system also reduces the landing distance of aircraft, especially on wet, icy or slippery surfaces

The reversing option adds about $10,000 to the price of the prop kit.

There are several safety features to the MT Reverse system to assure the reverse is only activated when required for ground operations, company officials noted, including:

• The system incorporates a static system pitot switch that will de-activate the system above a chosen indicated airspeed to prevent accidental activation in flight.
• The system will not activate above 1,300 rpm as the dual pistons lock together and reverse cannot be selected.
• The system has a reverse “active” warning light to inform the pilot the reverse has been activated.
• The system activation requires the master reverse power switch be turned on and the momentary reverse switch to be selected to enable the reverse.
