The Cessna 150 is a two-seat tricycle gear general aviation airplane, that was designed for flight training, touring and personal use.
The Cessna 150 is the fourth most produced civilian plane ever, with 23,839 aircraft produced. The Cessna 150 was offered for sale in the 150 basic model, Commuter, Commuter II, Patroller and the aerobatic Aerobat models.
The final Cessna 150 model was the 150M. It introduced the "Commuter II" upgrade package that included many optional avionics and trim items as standard. The "M" also brought an increased fin height, by 6 inches (150 mm). This increased the rudder and fin area by 15% to improve crosswind handling. The "M" was produced for three years: 1975-77.
In 1976 the "M" gained a suite of electrical circuit breakers to replace the previous fuses used. It also was fitted with a fully-articulated pilot seat as standard equipment. 1399 were constructed.
A total of 3097 "M" models were built during its three-year run. An additional 285 were built by Reims as the F150M and 141 FA150M Aerobats with the Rolls Royce Continental 0-240-A engine. Reims also built 75 A150Ls with F150M modifications.
Robyn Kelly's VH-WWO is fitted with a Teledyne-Continental Motors 0-200-A 100hp engine.
