Product Details
Description
Fiala FM-120
B2-4T 2 cilinder 120cc 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
engines FM 120 B2-4T 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 designer Zdenek Vlach has produced a real
winner, an engine that demanding modellers have been waiting for, for a very
long time.
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 120 B2-4T absolutely ideal for
your aerobatic model.
Being a
four stroke with a large capacity 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 Fiala FM
120 B2-4T is a four stroke OHV engine with two valves per cylinder, running on
petrol/oil mixture. Valves and their seats are manufactured by Honda,
ensuring a very high quality. The fully encapsulated valve train reduces sound
as well as ensuring the rocker arms are well lubricated. The aluminium
crankcase and cylinder heads are cast with the lost wax process, which enables
a very light weight. The FM-120 B2-4T's casting surface finish gives a very
realistic appearance.
The
cylinder's nickel-silicon lining is far lighter than conventional steel
cylinder liners.
The
processer controlled ignition allows easy starting and a exceptionally smooth
running in all throttle settings.
The Fiala
propellers are very efficient, this being due to minimal blade thickness. They
sound especially good on four stroke engines. Ideal Fiala two blade propeller
sizes for the FM120: 30x12", 30x14" and 32x12". For aerobatics
and glider towing the 30X12" is ideal. For big and slow flying vintage
models, as is with Paolo´s Aeronca C3, the 32x12" is the best choice
We
recommend Aral Ultimate 102, as the smell is not so penetrating and it can be
stored without deteriorating. It does not contain any Bio-Alcohol.
The fuel
consumption is approximately 50% compared to that of a two-stroke engine with
the same displacement. A 500cc fuel tank lasts for about 15-20 minutes of
flying time.
The FM
120B2-4T is also available with a starter. With the current version of the FM
120B2-4T the starter can be retrofitted anytime.
