This is my work to mount the DJI FPV air unit.
It works well with aliexpress clone frame.
You can use 4in1 ESC because of carefully located height of the camera cable.
There's wire duct under the unit for tidy wiring.
Use two 5mm standoffs in front.
Remove two standoffs behind.
Please use adhesive at the antenna notch to bond the antenna to the 3D print in order to protect the MMCX connector from crash.
Cubicon ABS, PLA
ABS recommended due to the high temperature of the air-unit
