Hello All ! I have a question about the RTH (or failsafe mode) feature... How or when is this set and how do I turn it on when in Phantom mode? I was flying the other day and I lost the phantom in the sun and was wondering how to get it to return to me without turning off the transmitter. As an example, if I go to a park, insert the battery and calibrate the compass, how/when is the return home feature spot registered on the phantom? Then if I go to another park about 3 miles away, insert a new battery, calibrate the compass there, when/how does the Phantom register the new home position? If I go to the second park, and do not calibrate the compass, does it register the new take off spot or does it use the return position of the first parks calibration spot? Or should I just use the s2 switch to manually set the new home position when I arrive at a new location? (I have a P2+ ver 3) Again Thanks in advance to all !
