    If you watched the original video https://youtu.be/A7x5NH8CTAU you'll know it started out as a motor mount review and evolved into a vibration test of several dissimilar props for camera drones. This time I'm focusing on three 10-inch props of similar pitch and materials to see how they compare in both vibration and noise. Links to thrust data are below.

    Aerials video are forthcoming once the weather clears

    Thanks for watching!
