This is not actually a mod.It's just a tweak to make the RC helicopter in Demolition man mission stronger.With this you'll just have to go nuts at the workers and guards who attack you without picking up a bomb as the timer won't start until then.
I decided to post this as many of my friends are not being able to pass this mission though it's damn easy.And as a result they are not being able to advance in the game.Hope this helps anyone who's stuck at DEMOLITION MAN.

Enjoy!
