Requesting a Propeller Recommendation

       Thank you for your interest in our propellers. It is our commitment to offer the Ultralight and LSA (Light Sport Aircraft) communities the safest, most efficient, highest quality carbon fiber composite propellers available. We also strive to offer them at a price that is affordable for the general light sport aviator. With that in mind, we are very proud to offer our selection of multi-blade Hubs & 4-Models of ground adjustable carbon-fiber composite Propeller Blades.

       We sincerely do appreciate your understanding, that requests for propeller recommendations are more efficiently handled, and better documented via written correspondence.

       You can supply the required data for the purposess of getting a Propeller Configuration recommendation either by completing the following table or by filling in our OnLine Order Form. Either way, we will do our best to response to your request as soon as possible - once we have ALL of the necessary information. Also, as a means of building a database for your reference for your propeller projects, you may find an existing setup that has already been field tested for your application on either our Applications webpage OR our Engine web pages: Rotax, Hirth...

       And if you wouldn't mind, if you have an application that is working well for your setup, we would be very happy to post the propeller configuration that is working for you on our Application page - if you would just drop us an Email defining your prop setup - that would be great.
