SERVICES

At Catto propellers we design and manufacture propellers for experimental, S-LSA and E-LSA Aircraft. Most recently we have also been focused on the development for a constant speed propeller for the Berkut, Cozy and Velocity style aircraft. This development will continue for other makes and models.

We can also provide consultancy services for custom projects, including drones, EVTOL, VTOL and more. Please inquire at info@cattoprops.com.

I have flown behind Catto Propellers since 2010. In that timeframe I have been able to evaluate these props for hundreds of hours throughout different environments. Flying Formation at airshows across the U.S. and Canada, racing at the Reno Air Races, back country flying, and in dedicated flight test collecting quantitative and qualitative test data. Catto Propellers are an outstanding balance of technology, innovation, quality and performance. Yielding a product that is proven, reliable and stands on its own. Even though Catto Propellers are outstanding, the Catto family is even better. Personally invested in the customer and standing behind their product 100%. Providing a good fit to customers’ demands. Looking forward to flying the next generation of constant speed propellers.

QUALITY

“The ASTM certification standards are going up all the time, and the propeller standards have become particularly difficult. The ASTM requirements for a propeller now require five hours at full rpm, 45 hours at 90% power, and 100 hours total service time. We worked closely with Catto on the certification, and the propeller performed flawlessly. Even before the ASTM certification, we had been using Catto props, which have consistently outperformed everything else we have tried.”
