I went into secret menu, to calibrate my camera gimble,and now the camera is stuck revolving in circles, with a clicking sound. Need help or phone number to Yuneec typhoon Customer service number. Thanks Bob
Are you talking about the menu on the ST16? If so, go to PAD, Settings and select Reset.
After that reboot the ST16, create a new model and then go thru the binding procedure. See if that fixes it.
