Editing helicopter handling/stats?

[Editing helicopter handling/stats?]

Is there any way to change the handling characteristics of the game's helicopters? For example by editing a particular config file somewhere?

I'm particularly interested in trying to edit the attack helicopters such as the AH-64D and AH-1Z. I want to make them more responsive/sensitive to rudder input... and perhaps tweak elevator input as well.

[Need Help Creating Mission Tasks/Scripting]

How do you create tasks for a mission? Particularly after the mission has already started?

In the mission I'm working on, I want the player to receive a task guiding them to the location of additional friendly soldiers that spawn at certain locations whenever the current number of soldiers in the player's squad drops below 5. Essentially, the additional soldiers will act as reinforcements for the player's squad in the event of combat losses.

To do this, I think I will need a script that:

-Constantly detects(counts) how many soldiers are in the player's squad/group.

-If the number of soldiers in player's squad drops below 5, it spawns several new units/soldiers at one of several randomly chosen locations(markers will be placed at these locations for script reference)

-Creates a new task directing the player to the location of new reinforcements

To further complicate things, I only want a limited number of reinforcements to spawn. In other words, I would only like for 2 or 3 groups of reinforcements to spawn. Otherwise, the player would have an infinite pool of reinforcements... and the mission would be too easy.

How should I go about creating this? And where would I place a script like that after creating it? In an external text file perhaps?

As I'm very new to the ARMA mission editor and scripting in general... any suggestions and ideas are welcome. Perhaps there's a simpler way to accomplish this than what I'm thinking.
