Does anybody know for sure the answer to the following question? While in flight, will moving the left stick all the way back/down shut off the motors on the Phantom 3 Professional? The reason I ask is, I understand moving both sticks down and towards each other (as in initializing the motors for start up) can be used in an emergency to shut off all the motors. But perusing information about operating the Phantom, I found that it says if you hold the left stick all the way down and hold it, it will also shut off all motors. Well I initialized the motors with the Phantom on the ground, and tried both ways, and both ways did indeed stop all motors. I thought if I had not read this, was flying pretty high and wanted to descend real fast, I might have just accidentally shut the machine off. I like the option of being able to do it using both sticks, but just holding the left stick back killing the motors seemed to be not good setup. So.... I ran the simulator and with the Phantom on the ground, the left stick back did kill the motors, But if I was flying, then I held the left stick down it would not kill the motors. Hmmm, still was leery, So I took the props off, initialized the Phantom like I was going to really fly it, moved the left stick up slightly and raised the Phantom over my head to simulate best I could that it would think it was actually flying. I held it there, pulled the left stick all the way back, and lo and behold, the motors did shut down. Again I think this is kind of a spooky option that could be a problem. Any one know if you can disable this option? Or am I missing something here?
