Dont be too slow and cautious..more time you spend mucking around getting out of a confine worse the recirculation will be, one of the few cases when you want to get it light on the skids and then go, you have to be absolutely positive your not going to get stuck in no mans land with not enough power tho. Have experimented sitting in a tight confine in a hover with the torque guage in the green then as its all started to circulate the torque goes up real fast..Coming in it's a fine line between Vortex ring state and recirculation, come in over the lowest point if you can and keep edging forward as far as you can, sometimes you just gotta pick the lesser evil in regarding wind direction etc

and do make sure nothing can get blown around
