    BC12D A75 Prop

    Those of you running an A-75 in your Tcraft- what propeller are you using?
    What type of performance are you getting?
    Static RPM's?
    Cruise RPM?

    Anyone running an A-80?

    Thanks,

      Would you know how your carburator is jeted for the A 75 compared to the
      A 65.
      How mush better is the rate of climb, is the 2 mph worth the added cost?
      I cruise 88 mph at 2200 rpm. 85 at 2150.
