That’s a bit of a pain but understandable if there is a vent.
Hmmmm. What to do. It’s a fly rig and the baggage handlers really throw these flight cases around and Velcro is the only thing I have found where the floorboard is still always attached to the wooden base plate after flights.
IF your board isn't covered in loop, you might want to try some dual lock tape. works like velcro but 1000 times stronger and stiffer. You can stack it high enough by putting a few pieces sticky side to sticky side, then just add as needed for height. It'll still be strong enough to lift the entire board by the remote without falling out or shifting around. Best pedal mount tape ever imo. FYI that stuff REALLY locks in hard so 1 inch pieces maximum!
