I wanted a secure way to mount a TBS Unify Race HV to my new HyperLite EVO frame. I whipped up this sling to do the job.
Print this in TPU. Use electrical tape to attach the vtx to the sling and slide over the middle standoffs. The sling will grip the standoffs and hold the vtx snugly against the top plate. As a bonus, you can see the LEDs through the top plate hole and you can press on the corner of the Unify to activate the button against the carbon fiber.

If you don't have a printer you can purchase this in a variety of colors from PB3D Creations.
