8178, I measured 11 3/8" for the prop diameter the box says 11.4" For some reason this thing would seem so perfect sitting on the front of your Blue Angel. I know the timeline is about 8-10 years off, maybe it's just because they were both designed by the same person, I'm just sentimental that way I guess.

I should add that this unit will never be used. According to the research I did (mostly here in this forum) these Variable pitch hubs were not the most trustworthy things to have spinning at 15k in front of your pride and joy, even when they were brand new. I might , however, make allowances in the nose to install it for pictures! Up until I bought this thing last Friday I had never considered myself a collector, never be able to say that again.
