So I am 1 week in to Spark ownership, I've flown 6 times in total, I have 2
batteries so tend to fly 1
battery at low level, say 2 metres from the ground and try to fly point to point, I live near some football (Soccer for the US members!) pitches in a sports field so I just fly to and from different sets of goal posts flying inside with me trying to get used to flying from both the iPhone screen view and LOS.
The other
battery I tend fly between H:80 and H:120 metres again using the iPhone screen to get used to flying sort of FPV mode as far away as I dare or until I get weak signal alerts. Just trying to learn how to fly bit by bit.
Just for interest I got H:84 metres and D:525 metres before I had my second signal loss and decided not to push my luck and let it RTH part of the way before I took control back.
My setup is:
iPhone 6
UK - CE mode
.900 firmware
DJI GO 4 Version 4.1.20
5.8G default setting
WiFi not OTG for phone to RC
I wear a lightweight waterproof jacket and find it so convenient that I can put the Spark in one pocket, the RC and iPhone in the other and the spare
battery in my trouser pocket and just go out for a walk to a local spot, the props are a little vulnerable like this but I accept that for the convenience it gives me.
On a previous flight I kept getting dropouts at H:50, D:250 metres but this latest flight, I flew higher (H:85m) and made sure I was clear of trees, also I paid attention to the antennae being long side pointing to the drone position in the air as previously I may have been nearer to having the point of the antennae toward the drone.
I still want to do the FCC hack as much for peace of mind over these sort of distances to improve reliability and not to start setting any distance records.
Cheers
