Valach VM 60 S1-4T 1 cilinder 60cc 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.
With the VM 60 the designer Zdenek Vlach has produced a
ground-breaking engine. The engine is 1 kg lighter than other four-strokes in
it`s class, because of only one camshaft, nickel-silicon cylinder lining and a
CNC milled crankcase. Anyway it is a robust engine with M5 crankcase and
cylinder base screws.
The carburettor is placed behind the engine, resulting in an
very narrow engine which fits into nearly every cowling.
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 Valach VM 120B2-4T 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 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 VM 60: 24x12", 24x14"
and 26x10". For aerobatics and glider towing the 24X12" is ideal. For
our big Tiger Moth the 26x10" is the best choice.
The fuel consumption is approximately 50% compared to that
of a two-stroke engine with the same displacement. A 300cc fuel tank lasts for
about 15-20 minutes of flying time.
The VM 60S1-4T is also available with a starter. With the
current version of the VM 60S1-4T the starter can be retrofitted anytime.
