This part holds the camera and transmitter for the AKK A5 FPV Camera System (https://www.amazon.com/AKK-Transmitter-Switchable-Quadcopter-Inductrix/dp/B073WV3HLS) There is a hole in the bottom for power to be routed through. Since the camera gets very hot without airflow, I have installed a heatsink on the shielding of the transmitter (not necessary but it helps) as well as an air duct on the top to pass air over the transmitter. This is meant to be mounted on an RC airplane where airflow is present. The transmitter and camera are held in by a small amount of hot glue to allow for the pod to be taken apart if needed.
