General Information

We produce a range of ground adjustable pitch propellers for ULM (experimental aircrafts, airplanes, trikes, paratrikes, flying boats, autogyro), aeroboats and snowplane with diameter of 1.6-1.9 m, left and right rotation, in 3-, 4-, 5-, 6-blades options.

Propellers are designed to be installed on the aircraft with engines with gear box and shock absorber (Rotax, Hirth, HKS, BMW TakeOFF, Simonini).

Maximum output power on the driving shaft for 3-blades propellers is up to 140 hp inclusively.
Maximum output power on the driving shaft for 4-blades propellers is up to 160 hp inclusively.
Maximum output power on the driving shaft for 5-, 6-blades propellers is up to 180 hp inclusively.
Maximum allowed rotational speed for all propellers - 2700 rpm.

Basic set of the props includes:
- hub + its installation kit (bolts and nuts),
- blades,
- pitch adjustment device,
- fastening bolts,
- blades covers.

Additionally propeller can be supplied with:
- spinner (hub fairing) Ø 226 mm (8,9"),
- spacer (distance separator) of 15 mm (0.6"), 30 mm (1.2"), 40mm (1.55"), 57 mm (2.25") or 80mm (3.1").

Propeller is fixed to the engine flange with 6 bolts. Mounting holes centers diameters is 75 mm. (Rotax, Hirth standard).

Bolt tightening torque: 25 Nm !

Spacer is used when you need to move propeller away from the radiator, engine cowling, exhaust system and flaperons. Increasing of distance between wings and propeller (for pusher-type engine power plant) reduces the noise and possible wing control elements vibration and improves of the propeller operation in whole.

The table contains examples of 3-blades propellers usage options for Rotax engine. For using different power plants please consult us.

Warranty period of propeller operation 12 months from the date of purchase, including storage, on condition of proper operation, storage and transportation.
