For FS9 do a google search for AS332 PP-MUM NO PX and read about the 3-axis autopilot in that
helicopter and how to install it in others. That's about the best FS9 has to offer , but it's a good one.
For FSX you have much more to select from.
I have installed this package and love it. So good to find these textures in one place. However it has a rolling action that I cannot get cured. How can this be corrected? Please advise. Thanks Billa (AKA Gringo6)
