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 170B2-4T Mk.2 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.
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 170B2-4T Mk.2 absolutely ideal for your big 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 170B2-4T Mk.2 is a four stroke OHV engine running on petrol/oil mixture. Valves and their seats are manufactured by Honda, ensuring a very high quality.
