Arma 3 - Eden editor: How to have a helo take off from a trigger

In this video I show you how to place a helo, have it stay on the ground and engines OFF until a trigger is activated. THEN the helo spins up and takes off to continue to whatever other task you have set for it.
Basicly:
1. Set down helo
2. Set "HOLD" waypoint
3. Set Trigger type to "Skip Waypoint"
4. Sync "HOLD" waypoint (it's set trigger activation or something like that.)
5. Set next helo waypoint(s)
6. Test it out!
I had a seriously hard time finding out how to do this. Admittedly I'm not the best mission maker or anything like that. I searched and searched for about 45 minutes trying to figure this out. Lots of people had scripts for it which wouldn't work for me since they were all written in like 2013. A lot of the editor guidance is outdated or incomplete. I really hope this helps someone else! Leave a like if it helped you out!
