This is a JR module case for OpenPilot OPLink mini radio. You can install your OPLink inside this box and then use it just like a regular JR transmitter module. I recommend to print the parts with Slic3r pillar support, rotated 90 degrees, so that the models are right way up.

Plug in USB during flight or install a bluetooth module to a spare port in OPLink for full telemetry awesomeness!

It comes in 4 versions, straightMMCX is the current model with straight antenna connector. The others are intended for the one with 90 angle, those are the ones that shipped after Kickstarter. The files with logo on them have OpenPilot logo bossed on top of them. Change filament during printing to show off the OP logo!

Install OPLink with antenna pigtail, install bottom to transmitter, make wires from module connectors to OPLink (needs 5v ubec), and screw the top part on. I used DIN7982 2,2x9,5 mm screws.
