Did they doctor the sound, or what is going on differently in the promo video?
I've never heard the Raider in person. I've spent a lot of time with the X2. The first time Kevin pulled pitch it got very quiet in the TM trailer. All of us looked up from our screens to see what happened. All the data said it was running but the noise went away. Those blades are magic. During the early no prop flights all you could hear outside was the S76 chase. I do not believe that video is doctored.
Excellent job S97 team!
