This is an rx antenna mount for the Diatone GT-M200 quadcopter frame, designed to be used with diversity receivers like the FrSky Xm+ or similar.
I designed the part to be used with two carbon fiber rods with a diameter between 1 and 3mm, I would not recomment thinner rods as they might bend into the props.
The rods rise 15° from the base of the part and spread in a 30° angle.
If you don´t have some lying around, I´d recommend you to use these rods:
After printing the part, cut the rods to your desired length and glue them into the holes using 2K epoxy. After the epoxy has cured, I attached the part to the frame using two M3 screw. After that, use heat-shrink tube to attach the rx antennas to the rods.
