"Hello Vladimir,
This morning I made a test flight. The propeller is doing very well!
It is better than the original one. (600 less rpm for leveled flight, but keeping it's rate of climb of 2.3 m/s))
I had to increase the tip angle to 14,8 deg.
The max. propeller rpm: 2200 (engine: 7700 rpm) (during flight).
temperature: 16 deg.C
humidity: 89%
I am very happy with it!
Best regards,
Paul Spaaij"
After the expiration of the appointed resource of 600 hours, the service life is extended by 100 hours after the examination. This is recorded in the passport of the propeller.

"Hi my friend Vladimir!!!
I´m ok and so happy with prop. I feel the plane a Little bit fast at cruise speed, not to much because is so dirty , but enough. Climbing is powerful then I´m happy. Everybody here likes so much this prop because materials and finish. But I just used your prop for 15 hours, I´m still waiting for Ingenier to get airworthiness Certificate. I made all with old prop and I have to finish it with it. "
Friends, I will be glad to the opinion and criticism of the operators. But there is one question. For some reason, few orders from owners of classic UltraLite to 450 kg. Their was little? They little fly?
I have to apologize to the customers who did not have time to put the propellers in the specified approximate time. Despite the selling hype, we must first ensure quality stability-even if it happens at the expense of manufacturing speed.
Some operators have come to the conclusion that the 2-blade versions of our propeller with a diameter of 1840 mm are more efficient than the 3-blade version. They acquire a 2-blade hub and remake their propellers on their own. RES is about the operators of the aircraft savage.
