DURANDAL-3
Product arrived safely, checked, assembled, ground and flight tested the same day.
Since testing in calm weather in the morning.
1st observation : it goes much faster than 4.800 rpm than with the EVRA, at the maximum continuous rotation speed of 5.500 rpm, the speed is slightly higher than 260 kmh, not bad for an 80hp.
No vibrations except below 2400rpm; although light.
So I'm delighted.
Small downside, the setting of the blades is laborious, it is almost impossible to be precise to within 0.1°, as the camera is so sensitive. Then the tightening systematically modified the tightening of one of the 3 blades, and always the same one. I still managed to obtain : 25.7/25.7/25.8

DURANDAL-3
The propeller suitable for the SPORTSTER is the 155 cm diameter DURANDAL-3 with adjustable pitch on the ground.
The test results are equivalent to those obtained with an ARPLAST PV50 Constant Speed propeller.
Perfect balancing. Weight propeller + cone + fasteners = 3,3 kg
Climbing rate: alone on board, I have 1600 ft/min, two with a 100 kg passenger, we have 1000 ft/min.
At 250 km/h, consumption = 16 l/h.
