Firmware updated, all batteries at 100%, full GPS lock. If you were to take off and climb until your transmitter lost connection, how high should you be able to go? Oddly I'm getting about 500ft before it loses connection and auto returns home. Something just doesn't seem right, its literally just above me at 500ft with my radio and wifi range extender pointing clearly right at it.... even FPV is still alive but controller goes out first. Yes its in FCC mode, 2 beeps on startup and yes I tried with fresh controller batteries, still about 500" max above my head before it loses connection. Everything else seems normal, it flys normal...etc. Any ideas? Have you tested how high vertically you can go before you lose connection (stock setup)?
