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.
