Adding another type of heli crash site

[Scotty1207]

Hi guys, I was wondering if anyone could tell me the way to add another type of heli crash on chernarus like a russian heli crash which would contain just Russian weapons and possibly even use the mi8 wreck model.

Thanks in advance

Edit: I've been looking at this thread about customising the loot in the default sites: http://opendayz.net/index.php?threads/editing-crash-site-loot-and-creating-more-spawns.6627/
