Thanks so much Richard, Rick and Jeff! I think I'll have a final posting tonight in completed projects!
Jeff: I think this may be a bit heavy for micro RC but there is a plan for this guy in P-nut scale which is just a shade bigger and I bet it would fly great. Of course, your idea of just using this download and cutting from depron would work a treat. You should go for it and keep us in the loop!

So here is the cowling progress. First, I filled the inside with epoxy and then this morning, lightly sanded the petals:

Then I filled with Tamyia putty:

And kept sanding, priming, sanding, priming etc...

Until finally...

I then cut out the bottom for the engine and painted the inside and out with black. Go to the finished projects later tonight and I'll post the beast all done! Looks pretty neat-oh.
Thanks to you all for encouragement. I agree that paper models make me very skeptical...until you see what real artists...especially our Polish brethren...can do with it. Just amazing. In some ways, our WWI subjects are really nicely set up for paper as the curves (except for cowls and spinners) tend to be pretty minimal. I have a flying boat, a large Albatros recon aircraft and the only Albatros rotary machine and a Hanriot all in paper in the background. This little guy was such a joy to put together and really looks so neat, I may tackle one of those next.
The Spider will look great next to my WNW Snipe!
Cheers,
Dan
