Me again. When building my F450 (not finished yet, may not be for a while since I got my PV) there was a lot of emphasis in how to vids stating that the blades should be balanced. Have any of you PV owners felts a need to do this? I would imagine it couldn't hurt and perhaps extend the motor life and reliability, and of course eliminate any added vibration, although that doesn't seem to be a problem with this quad. Just curious. :roll: Thanks.
