In another thread I posted that I had a chirping noise. I found it that it came from the main gear. I'm not sure if its the gear or the one way bearing, but either way, one thing that was noticed is that the one way bearing is tight. I have an evo 50. My friend has a used maingear with bearing installed. When he spins the lower gear and lets go, its spings for several turns freely. When I spin mine the same way, it stops turning as soon as I take my hand off the gear I'm spinning. It seems tight. So, should I oil it? Should I pack it in grease? Should I leave it dry? I've heard all 3 so far. I want to know other people's opinions on this and what is working for them. The whole heli has about 3 gallongs through it now. It didn't chirp from the start. The gear appears in good shape. No chips or cracks are in it.

Man, I miss the eighties.

Clean thoroughly, dry, lube with tri-flow.

Is it a sprag design or roller?

I read that once before. I'm trying to gauge what everyone else is using. That is one thing. I was planning on putting my bearing in grease when an online parts dealer told me that it doesn't help at all and that he wouldn't do it. He even told me that even if he did oil it, it would be with something light.
