Default Nimbus 2c wing templates

Hello from a fellow N2C owner. So far, my wings look pretty good.


Hi!


The FX-67-170 inner wing and FX-67-150 outer wing airfoil coordinates
available at the NASG airfoil database in a .DAT format. See:
http://www.nasg.com/afdb/list-airfoil-e.phtml

There are a number of PC airfoil plotting programs that can plot the airfoil
from the .DAT file format at the desired chord and save the shape as a .DXF
file. Many laser cutting shops can cut that shape in the material of your
choice from the .DXF file. I just had a set of airfoil templates made for
winglets out of plexiglass. The cost was trivial.


Tks for the info.

Can you point me at a suitable PC aerofoil plotting program?

Please excuse my ignorance, but I am very new at this, but I have a few
more questions.

First of all, how do I accurately scale the plots out along the wing?

It has been suggested to me that we get the first template cut for a
position 300mm from the wing root and then at 1m points out along the wing.

We'll presumably have to have a template for the end of the inner
section and another for the start of the outer section, given the change
in profile.

I am kind of hoping that there are people here who have done this before
and can provide some really good guidance.

I do not want to stuff this up!

Tks
