This is the wire rope isolation mount for the Phantom which has been made by NO MO Jello. http://www.nomojello.com/store/
Filmed on a windy day but as you can see there is no Jello in the video.
The Phantom No Mo jello mount I put together and have done no modifications so quite happy in just the first video test with it. Decided to film the DJI Flamewheel 450 made by my son as we were doing testing on the settings.
The Post above will also give you information on the Isolation mounts not just for the Phantom but also other quads.
