    Default Elevator hinge lubrication

    I’m curious about what others have used to lubricate the elevator hinge bushings on the newer series (5,6 & 7). Thanks in advance for any replies.

    There should also be no rotation of the hinge bolt under elevator movement.

    The movement is between the bushings. Edit: sorry I miss read what you said.

    LPS-1 has worked well on my M4 for years.

    You could probably use plain old motor oil on them to be honest, being rather
    simple bushings I think any kind of lubricant would be fine as long as you apply
    it on a regular basis. My only concern would be how messy it is.

    I think you're right, Jeff. I can think of several specialty lubricants that would be great also, and very long lasting, but LPS-1 is easy to apply, clean, safe on plastic, etc. LPS-1 it is.
    Thanks to everyone for the replies.

    My build manual had a section on lubrication and it spelled out specifically the recommended lubricants for each type of joint on the aircraft. I'm wondering if you guys have seen this? I think it is in the builder's tips, or maybe the final inspection section.
