Bought the Huey, the Ka and the Hip this year, wasn't keen on the Gazelle, too many complaints as of now.
What can I say, imediately stopped flying jets and I have them all. Somehow the Huey gets all my love now. It is just that good. Mi 8 is awesome too but a little easier on you if you manage to avoid VRS. Actually Mi 8 and Huey are the best modules in DCS, they are unbelievable satisfying to fly.
Never ever did I have a blade accident with the Ka by the way, friends of mine had, weird. I think we all overspeed the Shark or at least go pretty fast with it, I try to avoid this and that maybe helps.
Biggest problem for me is still taking off in the Helos, I have trouble to know what the aircraft is going to do which gives me a wobble sometimes.
Get the Mi 8 and the Huey !!!
