Possibly relates to reaction/movement speed, ie for cinematic you would want slow (soft) movement whereas racing would need fast reaction time to movements of the stickSo hardness or softness of flight? I'll have to do some testing still doesn't really answer the uestion I did read the manual
Yes I thinkLike how responsive the drone is to command changes.
Its how fast the drone reacts to a change input, so for example you might have max vertical speed set to 7 ft/s. When you jam the stick to get max vertical speed from hovering the higher the Global reactivity is the quicker it will reach the max 7 ft/s speed, so at 100% it will be almost instantaneous. Think of it as acceleration.
Maxing the settings could be stressful for motors? Just curious, maybe i'm overthinking
