Fiala FM140 4-Stroke Boxer Engine (with electronic ignition)
Product Details
Beschreibung
Fiala FM 140B2-FS 2 cilinder 140cc 4Stroke
At
Aerobertics we have been a direct Fiala / Valach dealer for years and we are in
direct contact with the factory. We also use them in our demo models and as a
result we have the necessary knowledge and experience about these engines so
that we can offer you the best support.
The Fiala
Motors FM 140B2-FS has the same well proven Nickel-Silicon plated cylinders and
the cylinder heads as the FM 120B2-4T on a new CNC milled crankcase. The longer
stroke of the crankshaft taken from the FM 170B2-4T increases the displacement
to 140cc.
Due
to being a four stroke, the low vibration is nothing but sensational, and
torque is really high. The response to the throttle being opened is so smooth
without the slightest attempt to surge, making the Fiala FM 140B2-FS absolutely
ideal for your big aerobatic model.
Being a
four stroke with a large capacity, it produces a very realistic full-size
aircraft sound. With a relatively small silencer the sound level is very low,
rather like a small saloon car. The silencers and headers for the FM 120B2-4T
can also be used for the FM 140B2-FS.
The Fiala FM
140B2-FS is a four stroke OHV engine running on petrol/oil mixture. We have
tried many oils and recommend Valvoline SynPower 2T oil. Our BEL-RAY H1R,
although excellent for two strokes, is not ideal for four strokes, as it burns
very well without deposit, therefore not much gets past the piston. With
Valvoline Synpower 2T a lot more oil gets through to the crankcase. In Germany
we recommend Aral Ultimate 102, as the smell is not so penetrating, it can be
stored without deteriorating and it does not contain ethanol! If in your
country petrol does not contain any ethanol, you can use any brand you like.
The fuel
consumption is only approximately 50% compared to that of a two-stroke engine
with the same displacement.
Valves and
their seats are manufactured by Honda, ensuring a very high quality. The
totally enclosed valve train reduces sound, as well as ensuring the rocker arms
are well lubricated.
The
processor controlled ignition allows easy starting and a exceptionally smooth
running in all throttle settings.
The Fiala
engines FM 140B2-FS looks just like an original aero engine, only smaller, it
runs smoothly like an original aero engine and above all it sounds like an
original aero engine. The legendary perfectionist Henry Royce of Rolls Royce
always insisted that an engineering construction to be right must look right. I
defy anyone to tell me the Fiala Twin does not look right.
The FM
140B2-FS is also available with a starter. With the current version of the FM
140B2-FS the starter can be retrofitted anytime.
