I am convinced that my prop needs balancing although it is very smooth at cruise, there is too much vibration at lower rpm settings. I talked to Ivo about balancing, but they have no solution other than to match blades in the factory. Best Regards!

The plate sticks to the panel or otherwise mounted solidly to the AC, and the spring hangs straight down. With the engine running at cruise RPM, the weight is slid up or down to maximize its vibration, at which point it is in sympathetic vibration with the rest of the airplane. The prop is then balanced by spraying a little matching paint or clear coat one of the prop tips. Just a dab will do ya', was the articles message. Start the engine back up and if the vibration increases, spray the other blade. Sounds like one of those things that would be tedious at first, but quick and easy once you have the routine down. >> Homepage: http://www.flyrotary.com/ >> Archive: http://lancaironline.net/lists/flyrotary/List.html --- [Pre-scanned for viruses by Internet America.] --- [Pre-scanned for viruses by Internet America.]
