You guys are absolutely right! The shots were done with an HMC150 on a remote controlled helicam.  A company called GravityShots.com met up with us in Whitefish one day during the end of the season.  Unfortunately, the weather wasn't cooperating with us very well (as you can probably see from the footage), but we made it work anyway!  It was really windy that day and at one point the heli got caught in the wind and started plummeting towards the ground.  Lucky for us (and the HMC150 strapped to the bottom) Jeff at GravityShots has been doing this for years and he corrected the freefall to make a nice little landing right next to the jump.  It was a fun day messing with shooting helicam follows - we learned a lot about the process and are hoping to include it more in the next project!
If you haven't seen the movie yet, it's now available on DVD on our website or in the NS Store as a digital download.  Woo hoo!
