Where you using any automated flight modes at the time you used GA? These are the only times the DJI G O4 is controlling the AC and not from the RC. Any other times, AC gets flight commands rom RC regardless of the status of the GO app or whatever is happening to the mobile device.
What would be the criteria for making it to the list of approved drones for transport? I would put on top of the list its safety feautures. Most DJI drones share the same safety feautures so most would get into the list of approved drones.
Try discharging it to zero and recharge using DJI charger. I read somewhere here that doing so initializes battery. It is what I do when I see significant voltage variance between cells on my P4P batteries. I did it once on my 1 year old batteries.
Transmission between AC and RC transmission will be my concern when flying close to a transmission tower. What kind of tower causes GPS problems? Dont planes use GPS too? Ken Heron have youtube videos on flight around some towers.
Compass error before take off will not let you start motor. Tested this awhile back with P4P obsidian and a magnetic ipad case as a takeoff point. I did not however tested it with the ATTI switch on before take off. It will not work is my guess even if ATTi is switched on because it will go...
When I registered with the FAA over a year ago and issued me my number, it said to put number on the outside of drone with suggested places to put them. The only thing new here is the mandatory part which I just assumed it was already when I registered.
I cant think of any reason why they cant implement this to all there drones other than marketing strategy. DJI GS Pro works on most of there drones. We will see this on our phantoms too. It better not be just for phantom 5 or I will be pissed.
Do you guys know when it actually updates the counter? Does it update the counter when battery reaches 100%? This is my guess. I always charge my battery to 50% and top it off when I go out flying. It does not count this as 2 battery charges.
