The Immortal T placement is not optimal if it's the only antenna you have on the quad, I use it because I use a diversity receiver with 2 antennas. This mount works well if you have U.FL to SMA adapters to attach your antennas for the air unit.
I printed it with supports, you might be able to get away with not using supports.
The author remixed this model.
Made the GPS space longer to fit a SAM-M10Q-5883 GNSS GPS, added holder for an Immortal T antenna.
