I see Airmaster is advertising a controllable pitch prop for the Jab 3300. Does anyone have any comparative performance data for a jab 3300 powered Sonex or Onex with an Airmaster or other controllable pitch prop on it?

Check the limits on the Polar Moment of Inertia for the Jab. When I checked to see if I could use a feathering prop for my Xenos, the answer was NO. Pete once said cranks have broken because people didn’t understand or didn’t care about this.
