Define the time a Patrol Heli is locked to a team

Where is defined how long the Heli is locked to a player/team? Is it this setting:

"Lock For X Seconds (0 = Forever)": 900,

Because I thought, this would only apply to the dropped crates, but I need to set the time for how long the heli is locked itself to the team individually. Meaning how long are other teams prevented from dealing damage to a previously locked heli?
 
Basically I am running into issues, where I want to protect the Heli loot from Convoy, but I can't find where to set the lockout time on the heli, so right now the Heli seems to be locked longer to a team than the Convoy itself, making it very hard/impossible for a new team to take on Convoy after another one abandoned it.

hi, that time is for both the heli and the crates. I can note down to add a separate time np

Appreciate it! Maybe it might not be needed anymore, though as the Convoy Plugin just got an Update so it takes care of the crate locking itself. So I can now just disable the Loot Defender option to lock the Convoy Heli and Bradley crates.
