I have been looking into my own method of mounting the APM with antivibration in mind.

To this end I wanted to source some freely available components specifically designed to reduce vibration.

I found a couple of such products which I am hoping will be ideal.

These coupled with a custom mounting plate, I am hopeful it will be a good solution.

First the mounting plate which will be cut from 1.5mm carbon fibre.

In each corner of the above plate will be an antivibration softgel bush which allow the plate to "float" on the main construction plate.


The APM case is then fixed to the mounting plate using SoftGel 15mm x 15mm x 5mm cube pads.



I'd be interested in any views people may have.

I have the parts here ready, but thought i would throw my prosal to the masses before the CF plate is cut.

I love the recent enthusiasm in anti-vibration considering that vibration can make your camera/photo quality horrible and can mess with your autopilot!  

Keep up the good work!,

where did you finde those rubbers ( the first right photo)?

+1 , good find, pls let us know the source.  I use to make my own using fuel tube as stand offs and vibration isolation  two in one.

The bushes are the S5 - http://www.gelmec.co.uk/GelmecSoftSiliconeGelGrommets.html

The SoftGel cubes are http://www.gelmec.co.uk/GelmecSoftSiliconeGelTape&Chips.html and supplied on a sheet of 25.

I'll let you know how I get on and post some pictures.

There are special materials created for vibration dampening and better than silicone. Search for "Sorbothane sheet" on ebay or elsewhere. They are of different softness and AFAIR this doesn't mean just the weight it can handle, but also the range of frequencies it damps the best. I would take the softest one for the APM board and also high enough, at least 6mm or may be even more.

Thanks Anton. I do also have a sheet of du-bro foam, however people seem to have had better success with a floating plate and mounting the APM just on the 4 corners to minimise the surface area.

Well, yes, you are not expected to use the whole sheet, but cut square pieces for corners and experiment with different sizes. Too small and APM will be floating too much and the flight will be unstable, too big and it will be too stiff and not damp much.

These are great and should work really well, I have posted links to them on the new Arducopter Wiki anti vibration page.

i had been playing with silicon earplugs with 10mmx6mm and 3mm internal hole.

I've found, at least for my setups, that the cheap, foamy earplugs generally work pretty well.  I use them to isolate the APM and a gopro 3 (around 6 of them will do it for the camera).  

The best results though that I've seen are from a combination of isolation and properly balancing the props.  Get the problem at its source.
