Vibration changes

Initially I started with this setup:

Initial Setup

Now with top shelf added:


When I attached the top support sheet, removing the receiver from the top of the APM itself, and moving it to the top shelf, my vibrations increased quite a bit.

They went from this:


to this:

I'm going to try a different type of O-ring first, to see if that will have a positive effect on the vibrations. Switching from the red silicone o-ring size 017 to a smaller nitrile o-ring size 015.

Now awaiting a battery charge to see how the new setup performs....

  • I personally don’t like o-rings for dampen vibrations, they create sometimes a Trampoline effect.

    Try ear plugs check it out at the Vibration Wiki page. I get on my 600 heli les then 0.05G in a hover.

  • Wow. Nitrile o-rings really didn't help:

    3692688617?profile=originalLooks like I'll be putting the silicone o-rings back on.

  • Lots of info about vibration management in this link Vibration Wiki
