Dynamic propeller balancing

in 912 / 914 Technical Questions 5 days ago

Is the dynamic propeller balancing procedure on a 2 blade propeller on a Rotax with the geared engine different than the procedure on a direct drive engine?

    I’m not doing anything differently. One accelerometer and strobe pointing at a piece of reflective tape on the back of my spinner. I can get it down to .04 ips with a couple washers and slightly longer screws in the spinner attachment screw holes. Quite straightforward. The only other method/tool I can think of to use the helicopter balancer with the second accelerometer but no idea what it would tell you about the gearbox.
