A really strong way to mount basically anything to your Radiomaster pocket using a Smallrig magic arm.

Disassemble your radio.

Slide the Outer Bracket onto the module bay on the rear of the radios frame.

Use an M5 bolt to secure the Inner Bracket temporarily to the inside of the frame, then mark and drill the two holes.

Remove the Inner Bracket and insert your M5 nut. and reinstall the Inner Bracket onto the inside of the frame using 2x M3 bolts. You want the M5 bolt to be trapped between the frame and the Inner Bracket, and your M3 nuts to be INSIDE the radio.

Put your radio back together.

Install the Outer Bracket with an M5 bolt.
