Another Foam board Spec wing

#1
This is my latest version of a foam board spec wing. I have not finished it yet so its untested but I am confidant it will fly great.
I used duct tape to cover this because I had a giant roll of red duct tape. I usually would use packing tape. All I had was clear and a white plane in the snow might be hard to find. The duct tape is strong but its heavier then packing tape.
the motor mount is 3d printed a regular X style mount just screws on to it with some small wood screws.

Airfoil
This is suposed to be a NACA 0014 to meet spec its pretty close

On my drawings I show the elevons at 1 5/8in wide that is very close to being to big. If I was trying to qualify the plane I would trim them down a little. The airfoil is within spec but on the thinner side.

This is half of one wing panel this is the template cut this out and use it to trace the whole panel.

this is the set up I use to shape the control surfaces.

The airfoil pdf is actual size print it out and trace it onto the foam.
I included a stl for the mount I am using
here is a quick video of me shaping the control surfaces.
here is the v1 version of this plane the 3d printed parts will work with this version and construction video here might also be helpful.

I finally got this wing in the air! I was not happy with the duct tape elavon hinges they were way to stiff and the plane is already heavy so I redid the elavons with packing tape.
