    I am new and have looked for this answer but can't find it and to me in the DJI tutorial video it is not clear how to do it. How do you regain control of the copter after signal is lost? When you do gain control is it still in GPS mode or does simple switching the switch to GPS put it back in GPS mode.
    Thank you

    If you had a GPS lock prior to taking off which means a slow flashing green light. In event you loose control signal it will enter the fail safe mode and return your heli to the home position you took off from. Ascending to 66 feet if you're below that, or staying at current altitude if higher, and flying back in straight line to home point. To regain control simply flip your S1 (right switch) to the center position to regain control then flick back to the top position. Simple as that.

    You can test this yourself simply by switching your transmitter off while flying to it enters into fail safe mode. And as your Phantom hovers above you before ascending turn your controller back on, then flip to the S1 switch to the middle to take back over, then flip back to the top position. Just be in an open field when testing to be on the safe side.

    Or in other words- >flip to ATTI mode (or back to GPS and then back to ATTI mode) to regain control when the craft is back in range and is in Failsafe mode.

    *and if you're using an older Tx or a non-DJI controller, be extra sure your throttle stick is centered or above, or the craft might descend or drop from the sky.

    Warning:
    That is how one recovers control if the P2V is functioning like it should.

    When it decides to fly away, then it is no longer doing what it was
    intended to do. Somehow the software thinks that it is getting
    control input to climb and travel horizontally, or that the hold-steady
    position is at a different place, or that it is a moving target. ???

    Can it remember a previous Home location if it has been powered off?

    Could it get a data burp in the GPS information, and suddenly think that
    it need to fly back to Kansas?

    If one gets involved in flying via the FPV on-screen video, and perhaps turns
    to keep the screen better shaded, accidentally turning away from the P2V,
    the WiFi repeater might not be facing the coptor, and the Remote Control
    antenna might be pointing directly at the P2V, resulting in unexpected
    loss of signal and control.

    So, immediately point the WiFi repeater at the coptor, and quickly, keeping the
    Remote Control antenna reasonably vertical, tip that antenna about 45 degrees
    from the line-of-sight to the P2V if the coptor is more than 45 degrees above
    the horizon.

    Does that sound right?

    Yes.

    Almost. After adjusting your repeater's flat surface facing PV, tilt your Control antenna to parallel the flat surface (tip pointing towards sky). Aim the repeater towards PV and your Control antenna will be in the correct position. If the PV is close & above you, aim the repeater up towards the PV, again your Control antenna will be in the correct position (tip pointing at your forehead).

    Think of the two control antennas on the PV as pencils pointing straight up & down and the antenna on your controller also pointed up & down. Think of the radio waves emanating in a cylindrical pattern away from the pencil radially in 360┬░concentric circles. Almost nothing flows out the tip (up). So if the pencils are side by side they get the strongest signal, but if on top of the other, almost nothing.

    After takeoff, fly your PV away from you then up, or up a bit then away once you've cleared whatever's immediately in the way.
