US army mast bumping training video....

[MadMuz]

This is a teaching tape from 1982 on mast bumping in 2 blade teetering helicopter rotor systems. I thought you might find it interesting, as some of it is relevant to out rotors.... The video is 20 minutes long and is filmed in beautiful, hi-definition (a la 1982)
