The module that IMHO provides the most satisfaction during and after completion of missions. This is real simulation experience at its best. I have/ had them all........thunderhawk, commanche , Janes longbow, all MSFS, all X planes, take on heli.....and more. This module however even outclasses other DCS helis. I am very fortunate to have flown helis in real life as well as a vast amount of military training sims too. So take it from me.....this is the BOMB.
