Hi! Hope the masses can help me understand a challenge I sometimes get.... When I fly to maximum altitude (straight up from take off) I seem to lose control of the drone and it hits failsafe mode (currently set to land rather than RTH) - what's odd about this is that I can still control the gimbal but no directional control is possible. Once it's landed I have to power on and power off the drone to be able to get signal back - I can then fly as if nothing had happened? Any thoughts?
