    Have you ever noticed how petroleums attract dirt? Especially motor oil. I understood that LPS 1 didnt do that so thats what I have used.

    Thanks Jim... I had forgotten, but now remember seeing that during my initial review of the manual (a few years ago now!). According to the beginning introduction in the manual, there is supposed to be a little "oil can" symbol on the drawings next to bearings, etc. with notes to designate the proper lubricant. It turns out that there are very few of these shown on the drawings, and none on the horizontal tail surface drawings. However, in the Final Inspection Checklist section at the end of the manual, it has a list of recommended lubricants. Sure enough, LPS-1 is listed for the elevator hinges.

    The rational for using LPS-1. I does not leave a residue to attract dust, which will add friction and wear the bearings/bushings.

    I believe that section in the manual recommends Tri-Flow for the rod end joints; it also is a lubricant that does not attract dust. LPS-1 and Tri-Flow pretty much takes care of most ongoing maintenance lubrication.
