Easy Foamboard Airfoil - the Armin Wing

by ExAir | May 17, 2012 | (77) Posted in Tips

Here is a way to easily construct a true, cambered airfoil from Dollar Tree (Readi-Board) foamboard, hot glue, and packing tape.  The technique allows making the entire wing, including the control surfaces, from one contiguous piece of foamboard.  These wings can be used singly or joined with a dowel or carbon arrow shaft for wingspans up up to 90".  Recommended chords are 5" and 7" for the airfoil component, plus whatever control surface you desire.

Within this overview video are links to more detailed videos on each step.  If you would like to see more about any particular step, click on the link.  If you are watching in FliteTest the linked video will open in the player window.  If you watch on YouTube directly, a new tab or window will open with the linked detail video, leaving the original video paused in its own tab or window.

* The color balance on this video is pretty horrific due to white balance problems with my video camera, different each take, and only partly corrected in editing -sorry for that.

Great video Ed. I've watched them all and alredy built my Delta wing. Starting replacement wings for an old fuse this weekend. Excellent job.

Now you need to get the rest of your videos over here.
don't forget the gyro video... I won a beer on that one!!

Terrific video Ed. All I have to do now is find the foam board supplier in Australia.....hopefully not too hard.

Awesome- I've watched all of these vids on YouTube.
I hope to see them all posted here.
I haven't done one of these yet but one of these days...

Did you peel the paper off the foam board and then tape or just put tape over the paper on foam board

Tape is applied to paper facing on foamboard.

Hey Ed, have you ever tried making a flying plank from a single Armin Wing Section? I'm making a prototype right now, based on the Nifty Flying Plank (http://www.rcgroups.com/forums/showthread.php?t=1077013), and I'm planning to make a second scaled up version. My current prototype is just a 7" Armin Wing with 3" elevons (10" chord), and it has a wingspan of 20 inches. My goal is to scale it up to a 30" wingspan (150%), and I might use 2" chord elevons. I know I'll have to alter the geometry of the airfoil considerably to get things to fit properly. I'm wondering if scaling up an Armin Wing will cause any unexpected flight characteristics?

Very nice vid on great topic. Building my second wing and having fun. I appreciate ya, please create another one. Do you have wing with paper pulled off and Minwax brown paper finish? Thanks

I built an (almost) symmetrical airfoil section (10" long, 7.5" chord) as a test using an "I" beam as the spar using DSFB. Needed to be more careful in the construction and I could have made it truly symetrical, but I did learn quite a bit from my 'off the cuff' experiment and will try again wi a full length wing as soon as time permits.
