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.

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.

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.

  • How to start Fiala / Valach 4-stroke motors - video

    How to start - Fiala / Valach 4-stroke engine starting video, presented on the 250 R5 engine.

    It was taken on the occasion of our participation at the end of April this year at a well-known and very well-stocked event in Germany at the Bad Sassendorf Spa. The event is called ProWing and our company has been participating here for several years.

    The purpose of the video message and additional written information is to show users how easy and seamless our engines can be started. The procedure may be differ ent from your usual procedure and from the startup procedure for 2-stroke engines, but it is clearly worthwhile studying and applying it in practice.

    This is all shown on a 5-cylinder 250 ccm engine, but this can be successfully applied to all our engines! Then starting is very simple, on ProWing even this engine started by Mr. Gerhard Reinch from Toni Clark with one finger and a little finger !!!
