Thanks to the scimitar geometry, with engine RPM, air load and airplane speed as parameters, by slight natural deflection, an automatic pitch change is produced in the outer third of the propeller blades, adapting favorably to each phase of flight. What differences can you expect in a scimitar propeller versus a classic straight propeller?

  • Faster take-offs and better climbing.
  • Similar RPM in normal cruising.
  • Less engine RPM in high cruise.
  • In maximum cruise and full throttle, the engine does not exceed the maximum allowed RPM.

The price of our scimitar propellers always includes leading edge shielding and non-reflecting black on the rear surfaces, with the choice of either transparent finish or one colour of lacquer, and the colour of the tips.

Paso Variable

Hélices de paso variable ajustable en tierra

Son hélices de tres o cuatro palas encastradas en un buje de dural.

  • Las hélices de paso variable en tierra nos dan la posibilidad de ajustar el paso según nuestra conveniencia, adaptándolo al uso que queramos hacer del ultraligero, optimizando el despegue, el crucero, o una solución intermedia.
  • Son aconsejables cuando el espacio disponible es limitado, (cuatripala si el espacio fuera muy limitado), pues logramos tener la superficie total de las palas necesaria con forma proporcionada de pala, que da mejor rendimiento que la hélice con palas muy anchas. Mejor que 2 – 3 palas muy anchas son 3 – 4 palas de ancho normal.
  • También tiene un funcionamiento mas suave y equilibrado al estar las masas de las palas mas distribuidas sobre el disco de hélice.

2 Stroke

2 blade fixed pitch propellers for 2 stroke engines

Rotax 447, Rotax 503, Rotax 532, Rotax 582, Hirth …

Designed, among others, for the American Rans ultralights: Coyote, Airaile, Sacota; and forQuick Silver, Flamingo, Chickinox, Tango, Bingo, Zenair etc. and for any other amateur construction.

Propellers machined from a block of laminated wood of maximum width 130 mm by 50 mm thick and length according to diameter.


diameter up to
42"(106 cm) 200
45"(115 cm) 205
52"(132 cm) 2015
62"(157 cm) 260

Lacquer in one colour plus tips 90
"Aviation" lacquer (one colour + non-reflecting black on rear surfaces + tips) 110

(21% VAT for Europe not included)
The standard final finish is transparent acrylic varnish.

The price of a double propeller (4 blades) is the sum of the prices of the two propellers comprising it according to its diameter.

4 Stroke

2 blade fixed pitch propellers for 4 stroke engines

We provide propellers for all engines used in light aviation:

Rotax 914, Rotax 912 y 912S, Jabiru, Lycoming, C-90, Limbach, VolksWagen, Citroen Visa

Once provided with the details of the aircraft’s engine, power, RPM, reduction gear and cruising speed, we can calculate, design and manufacture the propeller which you need to maximise flight performance and satisfaction.

Contact us and we will inform you in more detail.


Also, as an extra, the final finish can be in “aviation” lacquer: applying one colour all over with non-reflecting black on the rear surfaces, and red or another colour on the tips.

A composite shielding (glass fibre and resin) can be added to the leading edges.

The shielding of the leading edges protects against abrasion from small impacts (gravel, sand, etc.), especially during landings and take-offs.

It can also protect against bigger impacts, unlike other softer armourings, the force of the blow is distributed along the fibres, in more wooden surface, being able to produce in extreme cases the breakage of the armour without destroying the propeller.
