Early on Sunday I was out at Home Depot and acquired some additional raw materials for my RC plane construction projects. I got a 4×8 foot sheet of 0.5″ pink foam, a 36″ chunk of 2″ angle iron, and a new 4 foot steel ruler (I know I had one somewhere, but darned if I could find it.) Anyway, after my experiment with making a square box fuselage, I thought I would try making a wing with an “Armin” wing, as shown in the YouTube videos of Experimental Airlines.
It took me about 10 minutes to put together this 30″ wing, with a 6″ chord.
This is the simplified version of the wing, which has a trailing edge which is two thickness of foam board, and does not include an integrated elevator. The construction followed these directions almost entirely:
I didn’t get the tape down as smoothly as might have been hoped, but it still looks pretty good. I’ll next try the improved version with the tapered trailing edge, and maybe a carbon arrowshaft stiffener (although this wing seems plenty strong.)
