Bring it to a hover if you can, assuming you aren't going to 12 or 13 grand. Most jumpers will like a zero airspeed exit because they have no relative wind and the first 5 or 6 seconds of freefall are fun due to the inability to control yourself, until you get a little airspeed to work with. Balloon jumps are even more fun cause it's quiet. Axx over tea kettle, big fun. Please make sure they are aware that lost objects out the door are a mite more serious in a helicopter. Take out the duals if you can, peddals too. Just cause they jump out of airplanes doesn't mean they know anything about them. If you are hot loading jumpers have a reliable person watch them carefully. Wiggling around with a harness and container on makes for more things to get snagged and let's face it, civilian helicopters were not designed so people can easily jump assuming they have to start sitting with a seat belt. If you are lucky and have a 212 or similar configuration where people can sit with legs dangling just don't get busted because nobody had a seat belt on for takeoff. Do your wt. And balance. Most sport gear weighs 20 to 25 lbs and beware....they all have tiny cameras now so all you do will be recorded for review after the incident.
Jump pilots are not required to wear an emergency rig but there is a requirement to have one in the aircraft should the need arise. We all know you would never be able to put it on so if you can wear one, I would and have someone show you how to deploy it in the event your day takes a turn for the scary. Have fun, the party after sunset is usually good. If you are a low time Robinson pilot, you are over your head and should walk away.
