OK - couple things you'll see in this video.
First things first: this is the updated version of the helicopter - version 1.01
1) You need to use the helicopter collective and tail rotor controls - set up a helicopter profile separate from your fixed wing controller settings. I start this flight with my default aircraft controller profile - then pause and change it to the helo profile shortly after the rodeo begins and you can see the difference (even though I'm not the best rotorcraft guy)
2) you'll also see the late weather injection and winter ground textures about halfway through this video.
The scenery is 1S2 Darrington from ORBX updated today also..maybe the late 'Real Weather' injection problem is related to that scenery? I don't know..
