I just picked up a Vitus 320 but it has an issue and wont fly. I can get the app to connect to the ground unit and I can also see the wifi for the air unit. When I go into the app there is an exception , the details for it are "remote-control undetected". The app is connected to the controller and I have video so I would have thought that it was connected. I get that high pitched squealing sound when I turn the drone on and it doesn't go away. Is there a separate process for pairing the controller to the drone outside of the video feed? The manual is real thin and I can seem to find any info outside of the manual.
