Piper PA-32 trimotor pics?
« on: September 07, 2010, 03:51:27 pm »
In his fantastic autobiography FROM THE GROUND UP, Fred Weick describes an early attempt to convert the Cherokee 6 into a simple, low-cost trimotor, retaining the fixed gear and using fixed-pitch props.  This was actually tested by adding two 115 hp engines (O-235s presumably) to the wings and throttling the Cherokee 6's 260 hp engine back to simulate a third O-235 for a total of 345 hp.  Performance on all three engines was fine, but engine out performance was not.  Switching the 115 hp engines for 150 hp units solved that problem, but speed was now so high on 450 hp that controllable-pitch props were needed, defeating the original purpose.  That model eventually became the Seneca, but with two larger engines, variable-pitch props and retractable gear.

So, my question is, can anyone provide drawings or pics of the experimental PA-32 trimotor?

There is also a photo of the PA-32-3M (N9999W) in "Piper Aircraft" by Roger W. Peperell.
