I remember reading a thread about this a long time ago, but couldn't find the exact one I'm thinking of, so I'll just ask... Here's what happened to me today... I had the Phantom (v1.1.1) out about 100ft and up about 100ft. I decided to descend and come back towards me at the same time (using CL) - so I was pulling both sticks down and all of a sudden the Phantom started tumbling and fell out of the sky from about 60 or 80ft. Luckily nothing seriously broke and it flew just fine afterwards. I realized while it was falling exactly what had happened. I must have inadvertently moved both sticks all the way down and in - just like I do when starting the motors (and how you can shut them down). Watching the video afterwards, it confirms it - as you can hear the motors shutdown and the props stop spinning. My question is this... why the heck would the firmware on the Phantom allow the motor shutdown function above a certain altitude? I have my cutoff set to 'Intelligent' in the software. I thought that would prevent this from happening - but I guess not. Is there anyway I can prevent this from happening again (besides the obvious - don't put the sticks in that position!).
