The biggest thing that seperates AH2 from real life is the vibrations. On a seemingly calm day, I took off in a 1970s model low wing gruman 4-seater. Boy if that thing would have had a gunsight in it, I would have had trouble even looking through it.
But IMO, theres no realistic way to implement vibrations and turbulence into AH2. Many years down the road when everyone is using a scale cockpit hooked to hydraulic lifts, well maybe then it can be done.
