Flt control lube?

[jonstark]

What is the recommended or preferred lubricant for the plastic flight control bushings?

Do they loosen up a bit with use?

Thx,

Mine had a significant reduction in friction after lubing with LPS-1.

The stick controls seem to loosen up a small bit with use, but not too much (I am speaking with 360 hours on my plane). The rudder pedals are the ones you don't want any stickiness to begin with because the pedal springs are not very strong and they are what returns the pedal on the passenger side. If the passenger side sticks, that cable can go slack and you better hope your keepers don't allow the cable to jump off a pulley. Normally not a problem if you installed the pulley keepers correctly, but I just don't like a loose cable slapping around.
