If your heli has a tail belt and you had to take the belt off the drive gear to change the bearing in question, did you twist it the right way when fitting it again?

What heli are we talking about here?

I'm not familiar with this heli, But reading your thread i'd say it doesn't have a fully driven tail hence it only spins when the mains are turned counterclockwise, The jerky action could be caused by the clutch bell dragging on the clutch possibly a sympton of not having the engine aligned correctly
