Here's my mounting plate to fix a CLRacing F4 Air V3 flight controller board into the top bay of the Esky Eagle, also sold as the AeroScout. You'll need to remove the little plywood box in the top bay, then this sits down onto the wood plate. The holes should be threaded with an M3 tap so the board can be fixed with nylon screws. It's shown in these videos:
