Well Grubby, I guess it's a matter of personal conscience. If something bothers you, no matter how irrational, you've got to do something about it.
I was going to post a picture of this on the Aerodrome forum but I decided I should check my reference first. Those guys take things too seriously over there. Now, after looking at all the photos and drawings, I see I've got more than a few details REALLY wrong. It bothers me so I'm doomed and have to fix them :P

I'm also considering doing the whole damn engine too

And BTW, I'm out of my tree already but that's another story
