03/31/2009. Remarks by Johan Visschedijk: "Also known as the Wagner Twin 2, Wagner Twin Tri-Pacer, and Wagner Pacer 125, this was a standard PA-22 fitted with two 125 hp Lycoming O-290-D engines mounted side-by-side. The conversion was produced in three weeks by Harold Wagner from Portland, Oregon. To clear the two overlapping propellers the left engine shaft was fitted with a 4.75 in (121 mm) extension. After 100 hours testing, the aircraft was converted back to its original configuration."
