My DJI air unit did fit in my 3inch but not in my 5inch, I had to do something about it!

I decided to design an adapter to put screws for a 20x20 F722 mini DJI FC at the back of the frame, leaving room for the air unit above my regular 30x30 4in1 esc.
The air unit is squished enough to be held between the motor wires and the top plate.

And it flies awesome, 6s power, so light. Power to weight ratio is insane. I am never putting a gopro on a frame again.
