thanks da Rock.
I'm putting together the BH Models Spit. Tried to find a Hangar 9 but they're out of stock for a month. To my surprise when I inventoried the box I was pleasantly surprised at the quality of the BH. It'd be interesting to compare each others as we put them together.
One thing I'd bet,I'm sure your instruction manual is better than mine lol

Mine has the six collectors on each side. Also has the raised sections above the exhaust of the later versions.It's really stand off scale as the collectors point down and slightly back. So I guess I should be looking for more of a pointed shape then. Not that the rest of the plane is exactly true to scale, but if I can make it at least look a little more scale I'd like to

Other than Tru Turn, you know who might make a 3 blade spinner along those lines?
Want to use aluminum. Maxx products makes some decent looking ones at a reasonable price but don't have a 2 3/4" version in 3 blade.
