RE: spinner damage
More prop clearence,
I just noticed in the picture of your spinner that there isn't hardly if any clearence on one side of the prop. You should adjust it so the prop is in the center of the opening in the spinner or it might slip and eat away the prop enough to fail and hurt you or someone else. You always want as much clearence on both sides of the prop shaft as possible. If this is just an optical illusion I'm seeing disregard.
