If you were a big fan of the DJI Crystalsky mount, this solution is the best I've seen. ~$9, comes from China, worth the wait for me. It's a 3d printed part with a real nut. You can still store the joysticks inside, remove one thumb screw and the RC handles open. This means I can return to a smaller bag as I won't be using a mount that puts the monitor above the RC.
