Hi Folks,
We always prefer to use 2-blade props to play to the strengths of our clean & fast airframes. 2 blade props minimize cost, maximize reliability, minimize balancing issues, and optimize the performance envelope at both ends of the spectrum with the superior flexibility performance characteristics of wood or wood-core props. You'll have plenty of torque for takeoff and climb performance with the Rotax and the recommended Sensenich prop, which will also help you to maximize the speedster characteristics of our airframe at the top end as-well. Sensenich has a ton of experience engineering propellers and they have a huge database of both Sonex Airframe and Rotax engine performance characteristics -- we put our trust in Sensenich fully to come-up with the best prop for the job that is best-suited to this engine and airframe combination.
Regards,
-Mark
