Rhein Fantrainer
The RFB Fantrainer is a two-seat military trainer that replaces a conventional propeller with a mid-fuselage ducted fan, an arrangement West German manufacturer Rhein-Flugzeugbau developed from 1970 to give piston-trainer economics with jet-like handling. Early prototypes used troublesome twin Wankel rotary engines; the definitive Fantrainer 400 and more powerful Fantrainer 600 instead used a single Allison turboshaft driving the shrouded fan, after a Wankel-powered prototype crashed in 1978. It won a Luftwaffe basic-trainer competition against the Pilatus PC-7 and Beechcraft Mentor, though Germany ultimately bought few. Thailand became the type's main operator, ordering 47 Fantrainers in 1982 to prepare Royal Thai Air Force pilots for the F-5 Freedom Fighter.

The Fantrainer is easy to spot: a shrouded ducted fan set into its mid-fuselage, driven by an Allison turboshaft, replacing a conventional propeller.
