The Rhein-Flugzeugbau RF-1 was a prototype channel wing aircraft.
The RF-1 is a modification of the channel wing concept, that uses a single channel and propeller to eliminate the asymmetrical lift issues with a twin channel wing design. The "channel" is an airfoil-shaped section along the lower arc of the rearward propeller that produces additional lift from the propwash. The RF-1's propeller was completely shrouded, creating a hybrid ducted propeller. [1] Twin engine redundancy is maintained with multiple engines driving a central propeller with freewheeling clutches to allow for an engine failure. [2]
The aircraft had the unique shape to facilitate a channel wing design. The fuselage was composed of welded steel tubing with a composite skin. The landing gear was electrically retractable.
The prototype was built at Krefeld/Mönchengladbach and was only flown once. [3]

The Piper PA-24 Comanche is an American four-seat or six-seat, low-wing, all-metal, light aircraft of semimonocoque construction with tricycle retractable landing gear. Piper Aircraft designed and developed the Comanche, which first flew on May 24, 1956. Together with the PA-30 and PA-39 Twin Comanches, it made up the core of the Piper Aircraft lineup until the production lines for both aircraft were destroyed in the 1972 Lock Haven flood.
