Hi, I've just made a first test flight after having activated IOC Home Lock but to my surprise I couldn't see it take effect. I've set it up using a two-way switch on my Turnigy er9X, so when the switch is in OFF position, IOC Home Lock is active and when it is in ON position, IOC is OFF. I do it this way - being a newcomer to RC I find it safer if IOC is on by default. I'm using firmware 4.02 and my assistant is 2.20. On the Advanced-IOC page I can see how the blue field flips correctly between Home Lock and OFF when I toggle the switch on the Tx so I believe the receiver and Naza are correctly connected? The distance between me and the Phantom was definitely more than 10m. Any suggestions what might be wrong here?
