Hey all

Working on my first ARF assembly (Avistar) and having a problem with pushrod binding. I noticed the problem when my rudder / nose wheel servo was buzzing with no control input. Based on the pre-cut holes for the pushrod tubes, the tubes have to bend a little along their course to the servo, basically to accommodate the fuel tank. I figure the pushrods are binding in the tubes because the rods are straight and the tubes are not. Does that mean that the rods need to be bent exactly to match? Is there some kind of lubrication Ishould grease up thepushrods with? I tried to figure out a way to make the pushrods straight, but that would involve basically cutting new holes everywhere for them and that's not something I'm eager to do.
