Joe,
The only thing I'm in a crunch for is the scoop for my dual NACA ducts (the piece I tried to make a mold for). As far as re-making the single and double NACA ducts in carbon, that could be a winter project. I'm good with the plastic ones for now...
I actually need two of those scoops I was trying to make, one for each side. The scoops are gonna be a perfect companion piece for the NACAs when you start making those in carbon, you might even consider making it together like in this pic...look at the "vortex air duct" about mid page...

Thanks a million!
