I had a similar issue at first. I don't have my controller with me now but I went into the settings and I did the bind option again and the code was 1234567890 or 0123456789 can't remember which one and then it paired it. I bet you can find a YouTube video and how to pair the cgo2 for Q500. It should be similar. Hope that helps!I can't get the camera to power up even after re-attach. It was working fine Friday, then I messed around in the settings etc. and somehow made the camera not power up.
