A movie that decides the rotation in the sky with a snowmobile

It is a movie deciding one revolution in the sky with a snowmobile. In addition to surveillance and rescue activities at the ski resort, snowmobiles are widely active in snowy mountains and it is possible to run on snow at a considerable speed, but the car body should be quite heavy. How exactly can you decide this stunning trick if you practice it?

The playback of the movie is from the following.

The movie starts about 27 seconds from playback. Although it has been running well, sometimes there seems to be some momentum left over from the snowmobile.
