I ordered the one from McFarlane.
Smart move.
I believe you'll find that McFarlane supplies Cessna with engine control cables for all their piston engine line and the internal housing is a hard, slippery, composite type material (Delrin??) that never needs lubrication and.........
AND you can polish the aluminum housing that butts up against the panel making it smooth as a peeled onion......oh wait, I've heard that one.
How bout: It'll make it slicker than skunk oil?
