Feathering shaft grease

I was looking at finless bob's videos about the 450 pro build on helifreak and he suggested greasing the bearings on the feathering shaft. I haven't found any reference to the type of grease to use. Anyone have any suggestions?

greasing thinks on helis you should handle with absolutely care. Bearings, which have to "ẅork", are closed anyway and are maintenance free.
wrong grease can have a negative effect and/or destroy rubber and plastic rings.
i think, keeping things clean and free of fat is best.

If I was to use anything on mine it would be graphite powder. Does not hold dusk and grit so is less abrasive to moving parts. Just a bit messy to use sometimes
