Fiala is the only 4-stroke company in the world which produces both the engines and the propellers developed and designed to be used with them. They go hand in hand.

The Fiala propellers have quickly become a staple in the global UAV industry as no other propeller matches their efficiency.

Hence it is important to run the Fiala propellers with the Fiala engines should you want to run the diameters and pitches shown in the Fiala manual. These specifications are based only, and I cannot stress that enough, on their purpose designed and built Fiala propellers.

Other brands run the risk of over torquing and stressing the engine unnecessarily, limiting performance and service life.
