research NAZA.
Youtube it.
left switch:
Research Intelligent Orientation Controls for Course Lock and Home lock
Right switch:
research ATTI (Attitude), Fail Safe, RTH (return to home), Manual mode.
Once you understand and done the basic Phantom figure 8 flying, you can then enable NAZA in the PC/Mac Phantom assistance software.
And research catch lands.
Not having a go at anyone.. Though this is marketed as Ready To Fly (RTF),
I think it should be RTFM x 2 and then RTF.
If then you are uncertain, have a search on this forum and then post if you can't find it.
Fly safe!
