High performance propellers for ULM & LSA

We produce a range of In-Flight Adjustable and ground adjustable propellers for ULM and LSA (airplanes, airtrikes, powered parachutes, sea planes, autogyros, experimental aircraft, airboats and ski planes) with diameter of 1.7-1.8 m left rotation and diameter of 1.6-1.9 m right rotation in 3-, 4-, 5-, 6-blades options.

All blades have brass protection of the leading edge, which allows them to withstand the abrasive effects of soil particles and the erosive effects of water and significantly extends the life of the propellers.

Propellers are designed to be installed on aircraft with engines that incorporate a gearbox or belt drive reduction unit to slow the propeller rpm and provide shock absorption (Rotax, Hirth, HKS, BMW TakeOFF, Simonini).

Maximum output power on the driving shaft for 3-blades propellers is up to 145 hp.
Maximum output power on the driving shaft for 4-blades propellers is up to 180 hp.
Maximum output power on the driving shaft for 5-, 6-blades propellers is up to 200 hp.

All Propellers include:
- hub and its installation kit (bolts and nuts),
- blades,
- pitch adjustment device,
- fastening bolts,
- blades covers.

Available options:
- spinner (hub fairing) Ø 226 mm (8,9"),
- spacer (distance separator) of 15 mm (0.6"), 20 mm (0.8"), 30 mm (1.2"), 40 mm (1.55"), 57 mm (2.25"), 80 mm (3.1"), 100 mm (3.94") or 120 mm (4.7").

A Spacer is used to move the propeller away from obstructions such as a radiator, engine cowling, exhaust system, flaperons, etc. Increasing the distance between wings and propeller (for pusher-type aircraft) reduces the noise and possible external wing component vibrations. Spacers can also improve propeller operation by moving it back into less disturbed airflow.

The Propeller is attached to the engine flange with 6 mounting bolts.
The mounting hole bolt pattern is 75 mm in diameter. (Rotax, Hirth standard).

Bolt tightening torque: 25 Nm !

Propeller Warranty is 12 months from the date of purchase. Including proper storage, proper transportation and the conditions of proper operation.
