This fin uses the slots in the Floss 3.0 top plate and two zip ties to mount. It will hold a GoPro Hero 5,6,7, a TBS M8 GPS module, and a vertical immortal-T antenna. NOTE: if you use the t-antenna holder, make sure you have the ground plane side down and the active plane side up. the active element of the T is the one with conductivity to the center pin of the UFL.
Print in TPU with supports on the left side. 20-50% in-fill is fine.
The Zip-tie that goes front to back makes a full loop around the top plate.
NO PROPS IN VIEW :) Even with SuperView. GoPro tilt is 35 degrees
