Problem with Helos & Triggers

[Cloughy]

Arma seems to have issues with Helos and trigger. What i have done, worked in OFP no prob.
Basically i have three blackhawks, bh1,bh2,bh3. They are each in their own group, they, fly to through a few wps and arrive at the LZ, there are 3 invis H pads, as each helo flys over its H, i use the following in the trigger act field, bh1 in thislist && this, (this being the Blufor present) and in the on activation: bh1 land "Get Out"; bh1 FlyInHeight 0;
Now 2 copies of the trigger are use for the other 2 Helos, changeing the bh1 to bh2 and bh3 respective. Hope you understand so far. There WPs of the helos to these triggers are are 'move', then a transport unload (so it chucks out the the higher rank so i can run my unload script). They are on careless and hold fire and normal speed by now.
Also i have one group spread between the 3 helos.
Right now to the prob, for some reason, if i copy the choppers & trigs to another map it works, but bh1 activates its trig and lands, but bh2 & bh3 dont activate theres, they just stay at the WP before, no syncs or owt, so theoretically they should just bugger off, but they stay hovering. If i activate a copy of the trig with radio alpha, they land, but dont activate their transpoort unload trig, so they are still at the prev wp. Even though the move wp and the tran unload are 1m away from eachother.
Its as if the trigger wont activate because the bh wont enter it. Is there a certain height a chopper has to be to activate a trig, also anyone have any tips on a better activation, or does bh2 in thislist && this; do the job? Am i doing owt wrong? Or has ARMA trig activation changed?

One final point, the LZ is about 1000m from a commie occupied pita.

Cheers for the flood of help lol
If anyone who reads this is interested, i have fixed this.
I just make the bhx land "Get Out" trigger bigger, to cover where bh2 & 3 stop. when they land they kick out the higher rank in each helo, whichs lets me run my unload script.
It must have been locking at the transport unload, due to it seeing the commies in the distance.

Another point, has anyone else noticed, choppers with the player in seem to move slower, seems keep saying target that machine gunner, and when its finished, its goes on at normal speed, when i was in BH1 in the above mission, it did it, then when i tested it in BH2 it did the same, but BH1 flew ahead at normal speed.
