I got a drone not to long ago from my cousin who lost his controller, luckily i already have the same drone with the same contoroller. But I can't manage to connect my phone or my controller to the other drone. Is there anything I can do to reset his drone, so I can conect it to my controller or is this drone usless?

I have two P3S only one transmitter has my antenna mod. I bind either one all the time to the same transmitter so I can always use the one with the mods. Watch a youtube video on how to bind. If it does work P3S has a problem.

there should be no problem linking your rc to that ac unless there are issues with the ac.

Is it possible that the Firmware is mismatched? Can you check to see if any updates are done in that fashion?
