    Mooney Porsche Airplane

    I had the opportunity earlier today to visit one of Rich Lambert's customer's Porsche hangar in the southwest Fort Worth area. The guy owns the following vehicles:
    • 1966 RHD 912- this car was on the Porsche stand at the Johannesburg Auto Show of 1966
    • 1967 911S
    • 1973 914 2.0
    • Hughes helicopter
    • Mooney Porsche plane

    He also owns a 356 Cabriolet that is at his house as his current daily driver. He rotates the cars around for daily duties.

    The gray '68 is my car and the champagne yellow is Lambert's '69 913.

    From a previously running , but now defunkt Mooney airplane website :

    "Despite the small numbers of planes Porsche provided support for the engine in Europe and America. The Aviation Department was managed by Rolf Sprenger".

    In the photos , I'm assuming the white 912 is the 1966 Johannesburg showcar ?

    Can anyone shed any light on the rear Brake/turn signal assemblies . Was South Africa unique ? I see no red on the brake bulb area of the lens like a normal ROW lense would have. Also , are those small round reflectors on the lower painted section of the rear bumperettes part of the factory build ? I've never seen those.

    a rare plane today, got a chance to fly a porsche mooney, composite prop, no mixture or air cooling worries, just a simple u -shaped throttle control push ,push in for power, makes flying simple. engine proved to expensive to build, not enough power, believe porsche decertified the power plant for liability issues. most porsche power mooney were converted back to an aircraft power plant. Saw the adjustment of cam shaft gear driven timing, took a whole day to adjust. Porsche had two people who were certified to adjust the cam gear timing, one on the west coast and one on the east coast. thats all they did.

    More on the Mooney , from PP parts forum (seems about 41 planes sold) :

    (PP forum / 2001-02) :

    "It was an interesting engine to fly. The neatest thing about it was that it had a single-lever power control, much nicer to use than the standard throttle/prop/mixture quadrant. At the time I flew it, I knew a Mooney VP and engineer, Roy Lopresti, who told me that one of the problems Mooney faced was that the Germans refused to believe that a bunch of Texans knew the slightest thing about air-cooled engines. Despite the fact that Mooney told Porsche that they were going to suffer a huge cooling-drag deficit, with the engine and installation that they planned, the Germans looked down their noses at the rude boys and went right ahead anyway. The result was that they had to tune the engine for 212 hp to simply equal the performance of a vastly cheaper 200-hp Lycoming or Continental in the same airplane. The result: very few buyers had any interest in paying an enormous premium for no gain in performance, just to have the Porsche logo, a very smooth engine, and the admittedly nice single-lever power control. And Porsche _was_ trying to work with Cessna. They had a PFM in a Skylane, but Cessna declined to use the thing."

    (Another poster adding this from an an article he got somewhere. Although , i'm confused about the Mooney PFM 1988 introduction referance ? As you can see it flying around the world in 1985. ) :

    "We have to give these guys a tip of the hat for persistence. Over the last decade, electronic engine controls haven't exactly sparked a buyer stampede. Much as we hate to dredge up ancient history, the ill-fated Porsche Mooney PFM comes first to mind.

    Introduced in 1988, the PFM was a giant boulder tossed into the ripple-free, technological calm of GA. And it sank just about as fast. The PFM was powered by a six-cylinder, air-cooled engine with automotive-style electronic ignition, fuel injection, autoleaning, automatic cooling control and-what was supposed to be the irresistible marketing lure-a single power lever.

    It worked; push the throttle forward to go fast, pull it back to slow down. No prop, no mixture and no worries about shock cooling. Even though it was a bit slower than the 201, owners loved the airplane. Unfortunately, there weren't many of them. Only 41 PFMs were sold, a poor sales history due in part to the $60,000 price premium over the 201 and a flat GA market. Thanks to slow sales and money squabbles with Mooney, Porsche grew disenchanted and bailed out of the project. To its credit, it has continued to support the engine..."

    (3rd addition):

    "Did you know a pair or pilots flew it around the World in 1985 ? "
