ADJUSTABLE propellers
ADJUSTABLE propeller Model 2025
The new FITI ECO COMPETITION propellers, with diameters of 1580mm / 1680mm, are designed for ROTAX 912 engines with 80–100HP.
Special attention was paid to the ROTAX manufacturer's recommendation regarding the appropriate moment of inertia, which is specified in the range of 1500–6000 kg·cm². Our propellers have a moment, depending on the type, that aligns closely with the center of the range recommended by ROTAX. This results in smooth and balanced operation across the entire RPM range and contributes to the long service life of the torsional vibration damper and the slip clutch.
Compared to previous models of our propellers, these new ones feature higher starting RPM, a wider speed range, and lower fuel consumption. The new propellers do not place unnecessary strain on the ROTAX engine through excessive vacuum in the intake manifold, which in turn contributes to increased engine longevity.
