Finished rough sand of the cowl tonight. It's pretty unconventional shaped but it grows on you. I really love my balsa plane from Windsor Propeller. It has come in soooo handy. Removes wood much faster than sandpaper and more precisely than a knife. The more wood you can remove with the plane the less sanding. Spent ~30 min planing and 20-30 min sanding.
The air intake is a 1/8" gap around the 3" spinner. Tha area is:
(pi X 1.5625 X1.5625) - (pi X 1.5 X1.5) = 0.6sq in. That's not much but I still have some coutouring to do and the spinner actually sits 1/8" in front of the hole so the opening is a lot bigger. Remember the motor is mounted radially so it is in the airstream right behind the spinner. I also have my eye on a 2-7/8" ULTIMATE (listening Bill?) spinner that is way more pointy. I could add a scoop if it is really necessary but I like the 'turbo' cowl. Cowl weight is 6.5 now but those flat areas can be holed out since I'm covering it anyway. Maybe I can finish it up tomorrow.
Kirby - I'm building both Edges together. Helps a lot to see how everything is supposed to fit together. I'm shooting for a double maiden before SEFF.

This is a lot better than I thought. After going over it with the plane (pun).
Yep it creates a lot of chips. Man I bet that cost a lot of $
After coarse sanding. A lot better.
What the??? Have you gone nuts? Is this a ducted fan?
Jig saw and plane that does not fly.
scoop is 1/8" all the way around the spinner. Actually there ais also a 1/8" gap behind the spinner.
Nother head on shot. The last thing a bug will see.
