MECHANICAL ENGINEER MICHAEL COLE DELIGHTED EVERYONE AT THE MAYFLY EVENT AT OLD WARDEN BY RUNNING UP SEVERAL OF THE SCALE MULTI CYLINDER FOURSTROKE ENGINES THAT HE HAS BUILT HIMSELF OVER THE PAST TEN YEARS,
THESE ENGINES ARE MOUNTED ON STEEL FRAME MOUNTS AND ARE THEN BOLTED / CLAMPED ONTO A LARGE STAND WHEN MIKE WANTS TO RUN ANY PARTICULAR ENGINE UP,
MIKE ALSO BUILT THE FUEL / OIL TANKS AND NECESSARY PLUMBING TO RUN THE ENGINES HIMSELF,
I WILL UPLOAD THE OTHER ENGINES ( V TWIN + 3CYL RADIAL + INLINE FOUR CYL) RUNNING ANOTHER TIME,
MIKE SENT THIS INFO OVER ON THE BENTLEY BRS 9 CYL ROTARY -

SHE IS 350cc WITH EACH CYLINDER BEING 38cc,

THE CONSTRUCTION DRAWINGS WERE DRAWN UP BY LOU BLACKMORE WHO WON A GOLD MEDAL FOR HIS ENGINE IN A LONDON MODEL SHOW,
