I have a phantom 3 standard and I would like to do some birdside modifications. I currently have done all the modifications that can be done to controller. I use a boosted itelite dbs antenna on the controller. I have added four antennas to the bird. I am now considering a 2.4ghz amplifier birdside. I am also considering adding a second phantom 3 battery to extend flight time. Any thoughts or suggestions for hardware?
