I use ball bearings that permit the inner .375 ID pivot compared to the outer OD as the canard flexes in flight under load and not bind. It works well and is very smooth.
This upgrade was discussed here on the Reflector. At the same time replace the front bearing in the console. There cheap and have play in them that gets annoying on landing. It starts clicking and makes the elevator system feel sloppy! Mainly during landings due to the small correction in pitch during a landing.
