Since filming this video I have changed my mount, the new on has a qhick release similar to a tripod quick release and it also has a clear hole to allow a cable to enter into the bottom of the CrystalSky so I now use a 20mm long cable from there to the USB A socket on the bottom middle of the controller.
I’ll maybe add a photo or two of it on here next time I’m out.
This is the link to that thread, Launch Handle for Mavic 2 - #6 by SkyJumper there are a bunch of photos of the handle and a few other things.
Take care all
