its appearance: the vertical tail was swept back 35 degrees, with a short dorsal strake at its base, matching the styling of the Cessna 172 and other models. The cabin doors were widened, with 23% more area, and while the old doors were tapered at the bottom, the new doors were square, making it easier to get in and out of the cabin. The new doors also had larger windows and better latches. The baggage compartment was extended aft to the bottom of the rear window, giving 50% more room, although its load limit remained at . The cabin floor was now flat, with no hump for routing control cables. The old manual flaps were replaced by electrically driven flaps activated by a switch on the instrument panel; other former floor controls (the elevator trim wheel and fuel shutoff valve) were now on a small vertical console beneath the panel. The electric flaps now had a flap position indicator above the left door. The 6.00×6 inch (150×150 mm) main wheels with large low-pressure tires were now standard rather than optional, and they had new brakes. The stall warning alert, previously an electric beeper, was now a pneumatic reed horn that would work even if electrical power failed. The pointed propeller spinner and rear-view mirror options became standard for the Commuter and Trainer. Other newly standard features for the Commuter were dual controls (previously restricted to the Trainer), wheel speed fairings, and an electric heater for the pitot tube and stall warning sensor. The old optional Patroller-type door (with an extra window in the lower half) was dropped along with the name "Patroller", though long-range fuel tanks were still offered. The courtesy light option was also discontinued. Cessna greatly expanded 150 production for the 150F; a total of 3087 of this model were produced. The 1966 model year would be the single most-produced model year in 150 production history. (More 150Ls and 150Ms would be produced later, but those were spread out over several model years.) The 1966 model year was also the first production of French Reims-built F150s, with 67 built as the F150F. The 1967 model, the 150G, looked quite similar to the 150F but had many internal changes. The doors were bowed outward to make the cabin about wider, and the floor was lowered to add head room. Rubber sound isolators were added to the engine cowling to
