@willyman4121 Haha, thanks for the hard criticism, and your right to, it didn't fly at all! I did try one with a real airfoil cut from a template but it didn't work at all either. It flew fine in a straight line, but simply wouldn't turn at all, so I think if I moved the ailerons/elevators farther out on the wing and with more movement it could have better control, and then I could put a bigger vertical stabilizer it could have better stability.
@willyman4121 BTW, I did build a normal airplane with the same "real" airfoil I talked about and it weighs just 14 oz with a 5 foot wingspan and will fly for 20 minutes on a 800mAh battery, and it has an excellent glide ratio. It'll also carry a GoPro just fine for about 10 minutes, but the propeller is of course in the way being in the front. I will post a video nonetheless though, and I did make an onboard camera video with RCtestflight's "slowtrainer" that's on my channel.
me thinks you would need some reinforcing spars running spanwise. The Zagis have 3 thin carbon spars. Two on each side a couple inches back from he leading edge, and one across the middle that meets the two leading edge reinforcements. Without the spars the foam will flex greatly. Cool project. Good luck!
@menamiketrx The interesting thing is, while I have some 3mm carbon spar I'm not sure that its absolutely necessary,as if I hold it from the two wingtips it doesn't sag in the center more than an inch or so. Based on this, my thinking is that carbon would help, but probably the wing probably would still work without it at least in light winds. Keep in mind that the Zagi is made of EPP foam which is much more flexible and tough than the depron I used.
Biggest piece of shit, Sorry.

@Dth091 Why? Because it looks like a bomber of sorts?
