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.

Company Fiala prop s.r.o., division Fiala Motors - in year 2013 gained to manufacture propellers also a range of products now Valachmotors the former company, which is engaged in the production four-stroke model engines. Gradually they began to expand the range of motors and in year 2015 motors began commercial reasons continue to be sold under the brand Fiala Motors. For the German company Toni Clark will continue to distribute under the brand Valachmotors.

Outside the model usage company Fiala Prop developed special UAV motors. They are a 4-stroke boxer with electronic ignition, electronic fuel injection and an electric generator, standard 250 W, but may be reached even greater performance. These motors 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.
