Ahhh... I see. Really it's the same answer (sort of). It's a case of practice to descend with the trajectory you are after. Even if you looked at heli tutorial stick position videos they would not really translate to a fixed pitch multirotor.
Personally, I would get comfortable flying circles of differing size and tightness - in both directions but at a fixed altitude. Then, when you feel comfortable that you can throw a circe from any orientation just add down left stick into the mix which will then add a third dimension into the movement and you will have a corkscrew descent !![]()
OK, thanks! I'll give that a try.
