First flight with GoPro 9 on my Apex build

This is my first day out testing the new GoPro Hero 9: I used 4k with hypersmooth boost, but the boost makes the stabilization less smooth with quick maneuvers.
GoPro 9 is a fat beast and the quad feels heavy with a 4S Lipo, maybe it's about time to switch to 6S!
What do you think about the new Hero 9?
