You could try it in the simulator. With the "CSC Maneuver" setting, the motors stop in flight. The "For use in emergencies only" setting stops motors only if it detects a "critical error" (per the manual). I've never seen any authoritative, reliable info on what the Mavic thinks is a "critical error". Only guesses and suppositions.
I have my Mavic set to "CSC Maneuver" because I want to be able to drop it out of the sky instantly if I hear and see an airplane flying below 100 feet over the beach that's 300 yards in front of my house. It's illegal as **** for pilots to fly like that there, but they do it anyway. Last month I saw a Beechcraft Bonanza flying north over the beach at about 75 feet, right as I was getting ready to fly from my deck. This guy hadn't even announced his presence on the local CTAF frequency (I carry a radio).
To me, after 3 years, CSC is the intuitive way to stop motors. No way do I want that taken away and replaced by some combination of buttons and/or sticks that you never practice, and could never possibly remember how to perform in a collision avoidance emergency.
Anyway, gixxerbill, if it wasn't for your thread last week about your crash, I probably wouldn't have checked my CSC settings. I discovered that after the firmware update, my CSC had been reset to "Emergencies only". You made a comment earlier that the settings were poorly worded. I sure agree with that. Heck, I think they are backwards. To me "CSC Maneuver" seems like the setting to let you perform maneuvers with the sticks like that.

Wouldn't "Stop motors anytime" and "Stop motors for critical error" make more sense?
