Bart, a picture from my Piper book:
Designated the PA-32-3M and registered N9999W, the aircraft was "a quick rebuild of the original prototype Cherokee Six and was a non-conformity aircraft." The airplane's wings were fitted with two 115 hp Lycoming O-235 engines in pseudo Twinkie nacelles in addition to the 250hp Lycoming O-360 in the nose. The fuel tanks were removed from the wing and the wing structure beefed up. Tip tanks fed the two wing engines while a Pawnee fuel tank mounted in the cabin fed the larger Lyc. The two 115 hp engines proved anemic during engine-out tests and were beefed up to 150 hp. However, with the fixed-pitch props, the engine-out characteristics were too great and unwilling to put constant-speed propellers on, Piper cancelled the project.
