Hi,

in an attempt to fly over the top of a mountain near me, last Sunday I've incremented the top altitude that I can reach with my MA from 120 to 300 meters. But the drone disconnected at circa 270-280 meters over me, and begin the RTH routine (that I stopped when regain full control).

According your experience, what are the maximum height from the RC command that MA can reach (in Europe)?

I had the same in town with interference I was even disconnected after 160 meters of height, I suggest to try position antennas according to manual if you are flying just up above you. I tried then in area with no interference and reached 500m so definitely very sensitive for interference in CE mode.

Hi there, for this case, please make sure that the RC antennas are pointing to the AC in a correct position, please make sure the remote controller’s antennas are positioned parallel to and are pointed towards the aircraft and avoid the obstacles between the RC and AC. See if it could be better.
