This test was done to compare the vibration results of Gemfan 10x4.5 vs APC 10x4.7 props. These are what I had laying around so that's why I chose them. The props were mounted to my TBS discovery frame and using the iPhone Seisometer app I hovered for 30 seconds using each set of props. The video shows the vibration results and you can also seem them in the links below. I may give my 9x4.7 props a try just to compare the results.
