So I can program the switch in the software so all the way down can be fail safe , and if I have the go home and land setup in failsafe it will work like turning off the transmitter? Sorry for all the questions but since the store has let me learn about the Phantom I have been quit fascinated with it. I updated to the newest firmware and went through and recalibrated everything. Since then it is much more stable and locked in especially using GPS mode. Soon I will be checking out the HL and CL as well. I know I have to activate that function as well. Haven't done that yet. Trying to learn as much as I can so I can help out our customers. I am lucky enough to work for an owner that let's me do this. By the time I buy my own I hope to be a real veteran with it. Thanks again. Chuck
