RPX recently helped a RV owner with a Rotax 912 engine diagnose a complex vibration issue. Sometimes, dynamic prop balancing isn't enough to resolve a vibration. Isolating the source of the vibration was done using the DynaVibe GX2 to perform a full-spectrum analysis. We've produced a short video to explain the steps in diagnosing complex vibrations on this engine.
