I'm sorry to keep beating this subject to death, but words should have meaning. Part of my career was spent as a technical writer and it is obvious the writer for the DJI manual had no hands-on experience. In the MAIN manual, Stopping the Motors, Method 1 appears to be valid if executed properly. So I tested it (without props). Motors idling as they would be after gently landing, pull throttle all the way straight down, and then CSC. Result - the motors briefly speeded up before shutting down which would cause tip-over just like a direct CSC.
I then tried the same procedure but briefly (less than 2 seconds) held the throttle all the way down before CSC. Result - the motors restarted and went to idle. Briefly holding the throttle down actually stopped the motors and then CSC did startup.
Conclusion - Method 1 will never work. It will either flip you bird or restart the motors.
