Main controller data error

[Bert1984]

I am getting a "main controller data error" on my spark after replacing the camera and gimbal and at the same time I installed the 4hawks raptor Sr range extender. Can anyone help me on this. I'm really lost on this issue. Thanks.

haven,t had the issue with the spark i also have range extender but had a mech error on my mavic pro and had to get another controller the bill was higher than a new controller and i quit care refresh after troubles with the drone while using litchi all though they approve them they won,t cover or stand behind there product if using anything other than DJI
