I am trying to work out why I can't get more than 500m-750m out of my P3S with a DBS panel ?We have just opened the controller back up to check the press on connectors are tight and they seem fine . We always lose controller signal before video Is this the usual way it goes? The panel seems fine nothing lose or moving .I am going to replace the 5.8mhz lead with another I bought to make sure but I don't think it's the problem. I could only get 300m with the stock set up in open country so maybe the problem is with the transmitter or the Phantom its self. I'm considering buying another used controller to see if that helps.
