Ram Air Scoop

These were specifically created to install in the coro of the Ritewing Drak, but should work in any case where their scale is appropriate. The larger one is 34x50mm, and the smaller is 37x35mm.

Both come with a cosmetic face plate to glue on top of the coro so you don't leave ugly edges behind. I printed out of Taulman 910 nylon and used GOOP to stick them in place.
