Interesting, well explained. Looks like I don't need to change much when it comes to stickhandling, just practice more.
Adding a little bit expo to the Taranis gimbals also helps quite a lot. Not too much cause then you loose sensitivity, just enough to clear out the shaking of your fingers.
No I don't have Parkinsons, but sometimes when the adrenalin kicks in, it can be hard to keep the quad flying smooth.
I don't mean just adding expo to the rates in Betaflight, but via the menu on the Taranis.
This smooths out the sticks more directly, instead of filtering the stick movement through the flightcontroller.
