I am building a Sig LT-40 and have been following RC Ken's Pay It Forward Build. Everything has been going great. I am about to hook up my pushrods to the servos. After getting the pushrods to the rudder and elevator installed, I noticed that they were very hard to move back and forth. Much harder than I would have expected. They are installed correctly (I have double/triple checked) and look to be following more or less a straight path through the fuselage.

Is there such a thing as lubricating plastic pushrods? What else should I be checking? it's weird because at times, they push fairly freely but then get "sticky" again.

Thanks to anyone who can give me some advice.
