[TowerTalk] Loose rotor bolts

[Dick Green WC1M]

I've had mixed results with Hy-Gain rotor bolts. The bolts loosened up on
one of my Ham-IV rotors that's mast-mounted on an AB-577, but stayed tight
on another identical setup and on an identically-mounted Tailtwister on
another AB-577. I later moved the Tailtwister to a standard in-tower
mounting and it appears to be fine. I used Loctite on the Ham-IV that
slipped and haven't had a problem with it since. I'm not convinced the
Loctite is necessary if you use lock-washers and really tighten the bolts
down as hard as you can without stripping them. Checking the rotor bolts at
least once a year is a good idea.
