Thank's ...Yes it did come with GCU unit but went I spoke to with service they said it might be good idea . I never heard of doing that with a 550. I you go on DJI web page and scroll down
it now saz PHANTOM ONLY I guess we kit builders have to get info from each other He really only knew about the Phantom and it's problems. Does anyone use a GCU unit on there kit's? 450 ,550
Would it help at all?
Thanks William
