About the RF4D Fournier

The Sportavia Putzer RF4D Fournier is a single-seat motor glider featuring an air-cooled flat-four piston engine and a monowheel landing gear layout complete with wing-mounted outrigger wheels. Built from wood, this fully aerobatic aircraft is well-suited for sport touring and recreational pilots seeking a responsive flying experience.

Crafted as an aerobatic evolution of an earlier design, this model incorporates a landing gear system where the main wheel retracts forward into a fiberglass cowling. A notable operational highlight occurred when a pilot flew across the Atlantic Ocean during a prominent air race, capturing a performance prize for aircraft under a specific gross weight category. Maintenance routines often require regular attention to the main landing gear fork assembly.
