Sure happy to outline:
CAMERAS:
this one is nice and compact but a bit heavy but goes great against the leg for side shot. Too heavy if you need more distance to the drone.

WOOD POST
Then to mount it remotely - first tried wire.. that did not work since it caused too much shaking. Needed something light that's rigid. Balsa wood was ideal, very rigid, super light weight.

MOUNT
To mount camera to wood post I used electrician tape for the light weight camera and 3m-poster-strips for the first camera. To mound the wood post to the mavic I used the 3m poster strips.

Those 3m poster strips are AMAZING. Mounts cameras very rigidly to the frame and very easily removable without any damage or residue.
When all done the result looks like this:
The only tricky thing is for the shots looking up... from behind up to the bottom of the drone, is landing. U have to hand land the drone.. since the drone can't land with the wood stick pointing down.
