Turn your engines off to get even faster decent, thing is how high would u have to be to able to do that and restart engies and hover before crashing? The reason being is that I was being swooped on by a redkite and I could not get lower fast enough. Luckily red kite was not to determined to take drony out.
The engines are not turned off. The excellent DJI computer keeps it steady on the way down and the way up. It feels like a DIY sport quad w/ all the stability features and reliability DJI has to offer. Imo, the vertical performance is the main crippling factor.
The latest DJI drones use the same process as older technology, just better. They use PIDs and tilt per sec limits. I don't mess w/ those but I had to on the Inspire 1 Pro (X3) because the footage was bad. It's plenty smoother now. You can't do parameter mods on Assistant like you can do w/ the M2 and Spark. You have to use python/java software to extract the file which the drone reads in the root directory (after variable changing) to firmware update it for 10 minutes. The parameters are nearly identical for the Inspire 1 as they are with the Spark and M2. I didn't mess w/ the P4 as I couldn't get into it w/ 1.1.2. I don't want to firmware mod it as I use it for DroneDeploy.
If I went crazier w/ the presentation, I would have shown the telem sticks and the sound. I was observing it from the outside to ensure stability. It does not oscillate like it's going to fall out of the sky on the way up. It feels stock. On the way down, if you command full stick it can tilt back a bit (M2Z) but it's stable. The vert limits are 10 m/s. I'm not crazy enough to do more but you can if you want. It has plenty of power to do it. Even if you keep the vertical ascent rate stock, and mod the by down by 2 the change is massive. It takes so long to go back down but that is erased when you go to at least -4.0m/s.
