I have just completed 3 flights in the Agusta 109 Helicopter in ProPilot with no penalties. As ProPilot at the moment cannot handle the vertical takeoff and landing, you get the high angle of attack penalty if you takeoff or descend vertically, I found that to overcome this issue , if you do a rolling takeoff of only a few knots, or a landing with a few knots forward momentum , you will not incurr these penalties. Hope this helps all you chopper pilots.
