How to get rid of vibrations in your multi rotor helicopter

If you want to snap images or record video from your quadcopter it needs to be as vibration free as possible. When you manage that you get shots like these:

But when you start googling you get the same answer all over:

1. Balance your propellers
2. Balance your motors

But I did that:

And I still had vibrations, blurry stills and jelly-looking video. After a lot of trial and error found the solution.

It doesn’t matter how much you balance your props if they’re the wrong props. You need high quality very stiff props for aerial photography (AP). So, on the same quad, with perfectly balanced props I had lots of vibrations with one set of props and no vibrations with another.

I have had best results with Gaui props and Graupner E-props.

In addition to this I made a dampening system. First I tried to mount the camera directly on a small plate that was mounted on the quad with rubber dampers. That din’t work very well:

(Dampers = red)

Then I made a long extra board under the quad. Mounted it to the quad using four rubber dampeners and mounted both the camera and the battery on that one. Wow! No vibrations with any of my cameras!

Update:
And this is how video looks like if you don’t limit the vibrations.
