The Piper PA-8 Skycycle was a 1940s American single-seat light aircraft designed and built by Piper Aircraft at their Lock Haven, Pennsylvania plant. Towards the end of 1944 Piper announced a number of aircraft it intended to build after the war. One of these was the PWA-8 (Post War Airplane 8). An aerodynamic test aircraft was built with the name Cub Cycle and it first flew on 27 August 1944 with a small two cylinder Franklin engine.
