Given the phenomenal descent rare of 9m/s that the Inspire 2 claims, is this fast enough to "outrun" the dreaded vortex ring state or is there some detection and control built into the control system?

Sorry, rate, not "rare"

You can't out run a vortex ring. You can only feed it with more power and go down faster. Where is the 9 m/s descent rate quoted?

VRS can't be outrun, but can be managed.

Inspire can descend much faster than 9m/sec. Just do a CSC at 400 feet and you'll see just how fast it can go!

Next flight might be a bit tricky though...

Inspire 2 employs fast decending only when going down in an inclined decending path.

Only allowing it if you are also moving forward makes sense.  I don't ever go straight down with the Inspire, unless it's really slow.

Thanks Henry.  I though 9m/s straight down may lead to a few "warranty" claims from less experienced users.

Tried it!Yeah very fast

Try to avoid coming straight down , always add a bit of forward stick to prevent this  ( Vortex ring ) phenomena, also the NEW Inspire 2 has a fast descent but with the addition of some forward stick movement from what I have read.  Cant wait to get me hands on one .......


**** I should have read all the other post first- sorry I am apparently  repeationg other members, I guess I am a silly git........

Ring vortex is minimal on an inspire because of the tilt of the motors.  You will get some buffeting in a vertical descent, but you won't be dropping straight through your thrust column.

I almost lost a quad due to VRS, it was a pucker moment

I have to laugh at some of these posts.  They're hilarious!  In all seriousness, Donnie is right.  The Inspire is engineered with a "toe in" alignement that is supposed to reduce the chance of VRS.  However, no amount of engineering or sensors will substitute the experience of a good pilot.   Don't descend straight down no matter what.  It's simply a bad idea, and I've learned this the hard way.  Always be mindful of wind direction and speed, aircraft motion, and surrounding obstacles.  

It is my opinion that RTH should only ever be used in emergency situations.
