Fox,
You are at risk of entering VRS if you descend into your own column of descending air. If there is no wind, then this is directly beneath you. The rotors are pushing air down. If you descend too quickly, you may get yourself into that column of descending air and thus descend quicker with it.
Note that if there is any wind at all, this will move the column of descending air. This means that it could be diagonally to the side, or behind or wherever. You don't know which direction the wind is going at altitudes different to where you are standing. So this means you must always be prepared for all eventualities.
Good practice would be never to descent vertically in very low wind. If there is wind, then descending vertically shouldn't cause an issue because the column of descending air is not vertically below you.
Slowly straight down for filming, yes, or quickly straight down in wind. If I have to descend from high altitudes quickly, ie. with a full down throttle, I tend to come down in a wide spiralling trajectory just to get closer to the ground, then slow down and land or whatever.
Careful though, because you need to react when you see something out of the ordinary. Typical things to watch out for are drifting because you have lost GPS for whatever reason and the Inspire has gone into ATTI mode, or if you come straight down and you notice that it is wobbling around a lot, then there is a risk of VRS, so pitch (in a different direction if already pitching) rather than try and apply lots of throttle.
Just fly lots - and rather than going berserk really early on, just gradually go further and faster.
Beware of getting too confident quickly. Once you feel comfortable, remind yourself that actually, you shouldn't be Come back and read some threads about fly away, or crashes into trees / garages etc. That'll soon sober you up again
Anyway, fly safe and have fun!
