after using 27dbm mod more than 1 month and 200km+ travel distant, my p3s have some problem
1) shell cracked without crash, common problem for all phantom 3
2) wifi video + rc signal disconnected suddenly and can't reconnect until drone restart (after auto rth and landing), good luck for gps working well when it happen
3) rc normal but 2.4g video keep disconnect <> connected every second, drone need to cool down then it will resume normal
I fly under hot summer with 3 battery, and set 27dbm on drone side only (I have external amplifer at rc side with dbs-01 antenna, 5km+ ok ay country side and 3km+ ok inside city)), so problem should be caused by drone side
I use "Ojcze Nasz's" 27dbm mod (by hardcode at rc.s) and use my setchan.sh for scanning channel / force channel 13, I'm outside euro so dont need a loop for force ce to fcc (Argonaise's mod)
fly across the harbour and over the building
thats very informative, thanks, please elaborate a bit more:
how often happened 2) ?
did it happen more likely after a long flight with great distance ?
was it so from the beginning after installing the mod,
did it get worse within weeks?
(it might be a software problem,
my copter and also a friends had total rc+wifi loss with the need of power cycling, at a near distance one time after doing the mod (24dbm both bird and rc, no channel scan), but also had changed firmware the same time to 1.5.7 )
after which flying time does 3) occur,
after e.g. 15 minutes, or second/third battery in a row etc ?
it might be improved (besides by lowering dbm)
by better cooling of the gimbal mainboard,
venting holes + some kind of air baffle to use the prop wind
