Company Fiala prop s.r.o., division Fiala Propellers - is engaged in the development and production of wooden propellers mainly for hobby use. Recently, also props for special purposes eg. UAV . For modellers we currently offer size range from 12 "to 40" with different pitch. Standard 8 "- 22". All propellers are available as right handed (CW - clockwise) when viewed in the flight direction or a left handed version (CCW - counter clockwise) when viewed in the flight direction. This can create a set of propellers for multicopter. The basic design is CW.

There are two basic categories:

Classic (for gas motors)

Electro and electro E3

The basic difference of these two categories is in the construction, when the electro prop is relieved with respect to smaller stress caused by side effects of the motor (shock, vibration, etc.).

We deliver Classic propeler as 2-blade and more bladed - 3-blade, 4-blade or 5-blade. Version for 3-bladed propellers are also preparing for the electric version.

We offer a propeller in 3 colors: natur (natural), black or white.

All offered propellers are statically balanced and are delivered in cardboard boxes. Dimensions are burned by laser propeller and on propeller blade is printed logo.

This motor excels suitability for a given application instance. The fact that his ceiling is 5000 m above sea level and has an extremely low fuel consumption, allowing the device driven by aggregate lasted very long in the air without refueling stopover.
