had the same issue found a video on youtube, basically once both the H and controller, turn them both on and bind the camera, then go into the camera settings (little gear bottom right) and go to single team mode, select team, then go back in to bind and the h should show up, bind and go back to camera settings and switch back to single mode. do all the calibrations and you should be good to go!I think that there may be a problem there because I updated the ST16 firmware first and then did the TH so the ST16 isn't seeing the TH to bind
hope this was helpful.
