Got the AH-1W and CH-47D flying, they fly great. I haven't tried the others yet.
Only issue and I don't know if there is any way to resolve this is the AH-1W armament is pretty much unusable. I am using the KA-50 cockpit and the SHKVAL does not line up with the HUD. If I lock up a target the TOWS don't seem to fire either. The 20MM goes crazy and swings around wildly if I turn the SHKVAL on. The Hydras fire as advertised but HUD does not show a proper aim point.
It's great to fly the choppers even if the weapons don't work, thanks for the effort.
EDIT:
I was able to get the TOW's to fire, not sure what I did differently, the SHKVAL locks on properly but the HUD does not mirror where the SHKVAL is pointing. Lots of fun either way.
