[DFBHD] DFBHD Deathmatch Helo routine

[Cornish Pasty]

I'm fairly new to the art of map building and have pretty much got my head around most stuff involved, however:

How can I create this simple routine for my Deathmatch map?

(1) Blackhawk starts up and follows my waypoint list.

(2) On reaching the final waypoint, Blackhawk lands and waits for a few seconds.

(3) Blackhawk takes off and repeats the previous routine indefinitely during the game.

I am really struggling to crack this one and would really appreciate some help.
