No I was talking how the GoPro Mount onto the gimbal but you might want to check the wire the 12 wire that's gray and black that goes from the board of the Drone to the back of the gimbal
And I had this gimbal on my P1 Zenmuse & instead of a ribbing strip. Plugs into your GoPro on the side of it it has a plug that that is built on the board plugs into the back of the GoPro
might be interference with the receiver and your transmitter for your drone might be messing with it you might have to change your receiver and transmitter to Phantom 2 transmitter and receiver
It could be the ribbon strip the one for you plug it into your GoPro or it could be the ribbon strip the gimbal board where it goes into the actual gimbal do you get video on your screen
I would buy all your Phantom 2 parts but I'm in a nursing home and all I get $30 a month on disability all of the parts coming to me would have to be donated
