Hello. I own Phantom 2 v2 with fpv attached (Boscam Tunderbolt TS5830 1000 mW) and I have a problem with short flight time < 18min. There is no gimbal attached - just simple mount for GoPro camera. Is it Boscam Tx taking so much energy or it might be something different? Battery is new (97% base capacity). Ps. I'm new on this forum so please forgive me if I created thread in bad group or something .
