Cannot figure out syntax commands for this jump

[CombatComm 10]

Ok so in my mission, a couple Ospreys are waiting (via the this setfuel 0 syntax) untill anti air is destroyed on the ground. Than they take off with several fireteams planning to jump when they get to the drop zone. I have setflyin height to 400 but the V-22s always seem to swoop down last minute before the jump creating a pendulum effect slamming my men into the rocks killing most of them. Maybe its the stock parajump sqf im using I dunno. But I just need help tweaking this senario. Thank in advance.
