What rod end bearings are you using for the controls? Are they :
steel on steel,
steel on bronze composite,
steel on PTFE fabric
steel on PTFE composite?
Do you use rod end bearings with grease nipples?

Im suprised you havent recived any feedback. So i will put my 2 cents in. aircraft spruce may sell them, if they do i think it would be safe to say that they are aplication apropriot. I would probly would use steel with a ptfe liner.

I have bought my rod ends from Grainger for the past 25 years-- I have never had a failure due to normal workload --I use a cupped fender washer in case of failure but it has never happened. Mine are non greasable and I get well over 300 hrs of flying time before they become slightly loose and I replace them --at a cost of about $5 --I use the 3/8 shank and I have to machine a bushing to fit in the hole to accecpt 1/4" bolts--I simply buy a length of 3/8 Aluminum rod and drill a hole through the center. I then cut it to length and lightly press them into the bearing.
Of course if you dont like this idea you can always get "aviation grade" at significantrly higher cost--it it makes you feel better!
