Jason's Spitfire with an alternative engine By John Moore
< Back < Back
The   model   in   the   photo's   is   a   60   size   world   models   spitfire   which   has   clocked   up   many hours.   Owing   to   an   unfortunate   gravity   induced   incident   the   front   end   has   been   rebuilt and   the   plane   is   not   so   pretty   on   the   ground.   However   she   looks   great   in   the   air   and sounds   fairly   awesome   when   being   pulled   around   by   an   SC120   four   stroke,   which   gives an   impressive   turn   of   speed.   Currently   she's   fitted   with   a   91   four   stroke   as   the   120   is now residing in a blackhorse P40C Tomahawk
A Merlin running at 65in.Hg. and 3200rpm. Photo was taken at the airpark where a friend, Graham White lives at Cannon Creek Airpark, Lake City, Florida
He   has   collected   aircraft   engines   for   about   25 years.   Currently   I   have   the   Merlin,   Griffon,   P&W R-2800,   P&W   R-4360   (2),   Franklin   O-805   (flat 12) and Continental IV-1430. Due   to   the   high   manifold   pressures   he   runs   he recently   added   a   water   injection   system   to   it   as insurance       against       detonation.       He       has momentarily    “blipped”    the    Merlin    to    72in.Hg. and 3300rpm   which   is   well   beyond   normal   takeoff power    and    even    war    emergency.    The    QEC (power   plant   in   Brit   speak)   is   from   a   Canadair Northstar.   I‘ve   added   modern   spin-on   oil   filtration which   filters   to   5   microns.   The   unit   he   uses   is   an   industrial   hydraulic   filter   that   serves the   purpose   admirably.   A   feathering   pump   is   used   as   a   pre-oiler;   he   obtains   100psi   oil pressure   prior   to   cranking.   The   fully   functional   propeller   is   from   a   DC-3.   Being   a   Packard built   Merlin   the   propeller   shaft   is   a   standard   SAE   #50   spline   which   offers   a   whole   array of   props   to   choose   from.   In   the   photo   note   the   way   the   front   left   side   (right   side   in photo)   of   the   trailer   is   buried   in   the   ground   due   to   torque   reaction.   A   photo   cannot convey   the   unbelievable   sound   emanating   from   this   engine   at   any   power   over   about 50un.Hg.   It’s   no   exaggeration   to   say   that   the   ground   shakes   and   ones   insides   literally vibrate.    No    equipment    on    earth    can    possibly    record    the    sound,    it    is    simply    too overwhelming
