Yea, and the plastic sight is a pain in the butt. But it did teach me where to aim my cockpit for high (30 deg+) aspect shots.
I have the zoom set on my stick, but I'm still not really comfortable with it. I use it mostly to look at the aspect of the target 800+ out as somtimes its a lot higher or lower than I think (not that I shoot that far out - but to know how much lag or lead pursuit to fly).
The problem I have with the zoom is it maginfies the wobbles, and I wobble a LOT. It causes me to overcompensate - sorta like walking with bowl of hot soup staring at the sloshing soup

I think as I get more steady I might be able to use it more, or perhaps start with real low magnification and gradually increase it.
But you are exactly right, the little extra under the nose view translates to about no advantage up close.
