Hi, just joined up here from Italy. I'm going to get a Phantom 2 Vision in a while, but reading the Phantom_2_Vision_User_Manual_v1.10 provided, I have not understood some points: 1) Could I use rechargeable 1.2 Volt NiMh on the remote controller instead of using nomal alkaline batteries (1.5 Volt)? If not, could you advise me how I could use a different solution to power the remote controller? 2) The S1 switch has 3 positions. Ok, I get the up position is used to takeoff, toggling the switch is used to make the Vision in Compass calibration, and also to re-connect the link when needing. Are there other stuff to know about S1? 3) The S2 switch has two meanings in the manual, 1) Reserved 2) Flipping 5 times to set new gps home position. Same question... are there other meanings? 4) The remote controller uses a frequency of 5.8Ghz and this carrier is used in TX only. Is it true? 5) The wifi range extender uses a frequency of 2.4GHz and is used to TX commands to the Vision and RX video and telemetry data from the Vision. Am I correct? Thank you!! Take Care. S.
