NOTE: This mount is based around the Radiolink M8N GPS because that's what I had, it should work well with anything smaller as it has two zip tie holes, anything larger won't be very clean though.
NOTE: This mount fits really nicely on the Reverb, but is based around a 30.5 mounting pattern, so should work well with other frames like the Chameleon and Rooster, not sure for anything else.
ImpulseRC Reverb GPS mount, print in PLA with normal .2 settings, supports for wiring holes. Nice and solid mount, works fantastic and looks lovely and clean. I had to do a little trimming with the Dremel to get my Radiolink GPS in, but it's now a friction fit so I don't feel the need to adjust the design.
