How did my reply show up before the original post?
We all knew you were fast!
Wow, I have seen that happen on replies but never the Initial post. Strange.
God I love that movie!
Aim fast - Hit fast.
I find that the biggest difference in noise levels from my helo come from when I turn down the volume on the “Ride of the Valkyries.” 
That movie came out while I was still in flight school. Couldn’t have been better timing.
I built a model of that helo when I was about 12. Awesome movie, and I still have the model boxed up at my parents.
Man I’ve always liked the sound, always knew help was on the way.
For the real deal, Goggle “the quiet one helicopter”
