O.K. I think my problem is solved.
What I did was make a H pad and named it base_pad.
next, I made a trigger (axis a = 5, axis b = 5) and placed on top of H pad (base).
then I hit F-2 (group) and draged it to my helicopter named (helo) and grouped the helo with the trigger, which then made the trigger only be activated by (helo) being present.
I gave helo some normal waypoints and at the last waypoint in the on Activation field I wrote - helo domove getPos base_pad
Now, I can have my helo insert my troops, and then it will return to the helo pad that I want it too.
Thanx to all, and to all a Merry Christmas
