The Valach engines VM 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 Valach 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 Valach VM 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 cylinder heads are cast with the lost wax process, which enables a very light weight. The VM-120 B2-4T's 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 VM120: 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.
