RFB Fantrainer 400 / 600

This radical design by ducted-fan protagonists RFB was designed as a two-seat (tandem) jet trainer, offering low operating costs by use of a ducted-fan engine mounted aft of the cabin and fore of the T tail. A rotary engine was considered initially, but the specified Allison type prevailed. The design proved too radical for many and commercial success was not forthcoming. The Fantrainer only saw service in small numbers with the Luftwaffe and the Royal Thai Air Force.

what is the viability to reproduce this FRB 650 using new generation avionics

D. Howerton, 23.11.2011

Other sources say the RFB Fantrainer 400 was powered by a 425hp Allison turboprop engine while the 600 model used the Allison 650hp engine. Too bad the Fantrainer concept wasn't a success. As a former USAF T-37 instructor pilot, I think the Fantrainer had a lot of potential both as a trainer and as an observation/light attack aircraft. It's quiet operation would certainly have been welcomed by Tweet pilots.

I found out about the RFB Fantrainer just a couple days ago. I believed its a neat aircraft.
