The plane is located in ebps, for usf in 'ebps/races/aef/vehicles/paradrop_plane'.
Then open flight_ext\actions\attack_dive_actions\timed_action\subactions.
There is currently one paradrop_action, but you can add paradrop_actions as many as you want.
dude thank you for the speedy reply! sadly nothing seems to be working, for no reason now nothing seems to be saving, symbol icons, paradrops and even name changes.
