Reviews

I didnt notice an audible difference but could feel the instrument panel had reduced vibration. Also appears to have increased RPM at best power.

I installed this balancer on my O320 with a wooden prop. It reduced significantly the vibrations, that at all RPM. Very satisfied. Bon vols! Hervé, France.

My glareshield used to vibrate severely, and the compass was useless. I simply bolted on the balancer and went flying. I love it. My glareshield is perfectly steady now.

This device did nothing for my O320 and Sensenich ground adjustable prop. I could tell the minute I started the engine, but I went flying anyway and tried many different RPMs. I returned it and it took a long time to get my refund.
