Your heart would skip more than a beat if it didn't zoom zoom and the props spun off mid flightIt sure is irritating... If the drone is sitting on something unstable and not completely level, it just about tips over when it does this "double rev". My heart skips a beat when I see her rocking...

The most common reason heard here is to set the props (i.e. selt-tighten) others have said it may also be some sort of self-test for the ESC.
I cannot confirm this with any documentation.
