The Chequered Flag team decided to switch from sports cars to single-seaters
patron Graham Warner announced the Gemini (White's birth sign) Mk 1, this
was a conventional F Junior spaceframe with BMC mechanical parts and it
was based on the Les Redmond designed Moorland F Junior. The Mk 2 used
a Cosworth engine but was not especially successful although popular but
things changed with the rear-engined Mk 3 of 1960 which was able to challenge
the contemporary Cooper and Lotus designs. Suspension was conventional
with wishbones and coil springs/dampers front and rear, radius rods were
fitted at the back, a Cosworth Ford engine and five-speed gearbox were
standard issue. The Mk 4, although unsuccessful, was advanced for its
time (1962) with side radiators and inboard suspension and brakes, a six-speed
Jack Knight gearbox was used but proved something of a problem.
A few converted F
Junior cars raced very rarely in the first few years of F3 using both
BMC and Ford engines, they were not competitive.
