Fournier established his own organization, Avions
Fournier, at Nitray, near Montlouis, and there
developed a slight smaller and aerodynamically
cleaner version, still seating two side-by-side
but under a low-profile bubble canopy. The
prototype, first flown in 12 March 1974, was
powered by a 90-hp (67-kW) Rolls-Royce 0-200-E
engine driving a fixed-pitch metal propeller, and
certification was achieved in April 1975 as the
RF-6B.
The intended roles for the RF-6B were those of
raining and aerobatics, and the wood and
Dacron-covered structure was stressed limits of
+6g and -3g. On 4 March 1976 the first of
five pre-production aircraft flew fort eh first
time, powered by a 100-hp (75-kW) Rolls-Royce
Continental 0-200-A engine with a fixed-pitch
wooden propeller, as adopted for all subsequent
production examples.
Production ceased after 45 RF-6Bs had been built,
the last of these being a development aircraft
with a 118-hp (88-kW) AVC Lycoming 0-development
and production has been taken over by Slingsby
Engineering in the UK, and the first British-built
RF-6B was scheduled to fly in May 1981. A
small batch of wooden aircraft was fallowed by a
glass fibre version.
