How to prevent helicopters from crashing ?

[Dogmeat of Finland 10]

I have tried to make some missions where gunships engage targets like infantry. The problem is they almost every time manage to fly too low while attacking the enemy and then they just crash and burn. I tried commands like "helo flyinheight 80" but they don't seem to have any effect during the attack run (sometimes they just ignore the enemy if they are flying too high). Are you guys using any kinds of scripts to prevent this?

Try PMC appache addon, better at engaging enemy infantry from distance.
