I am having problems with my P3 4K. I get a error message that says "weak remote signal" Not sure where the problem is but I just replaced the ESC board for a different reason. I actually replaced it twice because of that message. I know it is not the board. I tried a different remote ( for a P3 4K) and I get the same message. Also I can't link either remote. I do get a view of the camera. I can move the camera but I can't record. Basically the remote won't link. I want to try new antenna but can't find info or a replacement part for them. It looks like a combination of the P3 Pro/adv and the standard drone. 2 look like the Pro and 2 attach to the ESC like the Standard. Ideas as to what i screwed up?
