I've been flying my SE beyond 2000m with 2.4ghz, so frequency is not the problem!
Most likely you are flying in a place with interfering signals or you are doing something less correctly, like not having your controller pointing to the quad oer havnig obstacles (trees, hills) between you and the ac!
BTW if you have android you might find it impossibile to switch to 5Ghz, I can't since I stupidly updated to firmware 1.5.40, but it seems it is no longer a problem with fcc mode!
Thanks Andy!
I was flying to the “Monza Park” and I had an open field for about 300m and then the woods began.
I thought the trees were not a problem ..
However that's okay!
I’ll try in an open field and see what distance I’ll reach!
Ps: when I used DJI Go with last FW I could only change the frequency of the downlink (video transmission) choosing between 2.4 or 5ghz.
The transmission between RC and AC instead (the uplink), was not modifiable.
I’ll let you know where I’ll arrive! [emoji3]
