Hello to everyone!I would like to share my latest phantom 1.1.1 "mods".Maybe some of you would like to give them a try.My phantom is equipped with 9450 props a BGC gimbal a ts832 transmitter a N1 OSD and of course a camera(sj4000).The first one is about the BGC control board.I placed it inside to improve the appearence.The second one and the most important was to improve the flying time.I was flying until last week with multistar batteries 4000mah 3s.AUW was 1230gr and i was able to fly for 9-10 minutes but i wanted more time in the air, (like all of us).My solution to this was 18650 batteries, so i bought 6 Samsung INR 18650-35E (3500mah) to make a 3s2p pack (7000mah).The pack is placed permanently inside because of it's size.The new AUW is 1300gr.The results after 3 flights was as expected.19-20 minutes of flight.The cells in 19 minutes under load was 8.6v (2.86 per cell) and after landing 10.15 (3.38 per cell).The only problem is that if you try to get some height in the last minutes, it climbs like it's "dizzy" because of low voltage.The batteries after the flight's was warm but i forgot to measure the exact temperature.The space inside the phantom is limited as you know so it's impossible to fit 2 more batteries to make a 4s2p pack.
