Mr Wagner's second attempt produced an even uglier machine, called the Twin Cub. It consisted of a J-3 Cub and a PA-11 Cub Coupe fuselage mounted side-by-side using a small wing center section and central tailplane. The outer wing panels and tailplane were standard components. The resulting aircraft looked so odd that even Mr.Wagner called it "The Thing". Because of the close proximity of the fuselages, only the righthand one could be occupied by a pilot and passenger, the lefthand fuselage serving only the purpose of engine mounting. No propeller synchronizing was envisaged, the props rotating in different planes instead, to prevent hitting each other. This was accomplished by a 'distance piece' on the lefthand engine/prop combination. It is claimed that flight qualities were just great, even with one engine out. One wonders, however, with all that propwash interference.
Even though the purchase price was said to be about half of a regular twin engined aircraft, the Twin Cub remained a one-off and Mr. Wagner turned his attention to the Twin Tri-Pacer, where he bolted two engines to the nose of an otherwise standard Piper PA-22 Tri-Pacer.(background right)(see background in right photo).
None of the Wagner conversions achieved commercial success and both the Twin Cub and Twin Tri-Pacer returned to standard configuration
