Dear Marco, for using Hobbywing X8 Motor above 2500 m over sea level, on your youtube video show a setup 12A Batteries and an approximate flight time of 20 min with 4KG Payload, could you confirm what flight height you had when you tested the drone ? And what could you recommend so that the performance of the drone does not drop at that height?
On the other hand, regarding the configuration with the Pixhawk 2.1, do you have any details or recommendations for the antivibration assembly and if you have had problems with electromagnetic pulses with the compass and the GPS in autonomous flights, if so, what recommendation could you give us for the project?
