Hi
I have just updated the firmware on two Inspires (using the correct firmware from DJI). One of the copters is an Inspire 1 and the other is an Inspire 1 pro. I have updated to the latest firmware v1.9.1.30. Both copters have a master and slave controllers however now I am stuffed on both because although both slave controllers see the aircraft and see an image neither controllers sticks seem to work (no pan and tilt or yaw). What am I doing wrong???

Hello Joe, before upgrading, everything is working fine? the firmware for remote controller is the latest?
Would you please calibrate it, and then setup controllers again?
Besides, you could change master and slave controllers to have a test.

I have  noticed that after the latest upgrade, I must elect to transfer control to the Slave Controller on the DJI GO APP before it will work.

Just to make sure there are no odd presets after the update, please perform the following button combination to reset the RCs:

* Turn on the controller, and the aircraft should be off.
* Press C1, C2, and shutter on the controller then turn the controller off.
* Turn on both the aircraft and the controller and link the remote.

After that you can set them as slave RCs, ensure that you "request control" in order to get joystick control of the cameras.
