Just unboxed, firmware upgraded and took first very short flight with Mavic 2 Zoom

First thing I noticed is how quiet it is compared to Spark, I wasn't really expecting that.

Ya Mavic series is exceptionally quiet apart from the Mavic Air..    in reality still actually very similar decibel levels but the sound it makes isn’t so shrill and blends into background way better the hum it emits is much lower in frequency and more times than not it’s so stealthy you can hide 50 feet away and people wouldn’t know its up there.  That’s something I really miss having moved to the Mavic Air...

I still love the discreet size of the Spark and predict I will probably fly it more than my Mavic 2
