NACA Style Duct

thingiverse

UPDATE 27 August, 2017 If you are looking for the version of this to fit a Mini Talon hatch, please go to my Wiki parts page:http://www.itsqv.com/QVM/index.php?title=Mini_Talon_Parts_Compilation UPDATE 4 August, 2017 I added two versions of these that fit a slightly curved surface in the event your model surface isn't flat. More versions found I did find two more versions of RC NACA ducts here on Thingiverse:https://www.thingiverse.com/thing:1854774https://www.thingiverse.com/thing:455438 I designed these to emulate the NACA ducts you see on aircraft which are designed to collect large quantities of air without creating too much drag. I did not optimize them using any CFD methods for their sizes but they were designed to the Nasa/Naca design guide. I use them anywhere I feel an extra bit of cooling air might help. The included picture is the 32mm (width) version on the hatch of my Mini Talon.
