Starting a helicopter

A multi camera shoot of the start up sequence of the bell 206. The techs are doing a vibration test on the tail rotor as part of schedule maintenance. Filmed using gopros, extreme cams and panasonic p2.
I've trimmed the warning tone down to about 4 seconds in this one.

Unfortunately the instructor did not put on headsets so the talking after start up is hard to hear.
