FRSKY r9mm mount for Mobula 7 HD

thingiverse

I got fed up with burning mosfets on the crazybee flight controller for my Mobula7HD (yes, I used the 9000kV motors, yes I had the capacitor on the battery), but I didn't want to give up on the dream of flying 3S. So I swapped out the flight controller with a GEPRC GEP-12A-F4 board. The issue was that this controller doesn't have an integrated receiver. Luckily, my transmitter came with a bundled R9M and R9MM module - it was just a matter of installing the R9MM model somewhere within the tangled mess of wires under the canopy of the Mobula 7 HD. This is what I came up with. It mounts in the stud that's usually used to secure the mostly useless "breathing LED" board. So that it wouldn't interfere with the VTX or camera, the R9MM wire dipole antenna was turned 90 degrees with respect to the board. Then, I threaded it through the frame below the camera, above the battery bay, and hot glued it around the perimeter of the rear fan ducts.
