New Project: 35" In-wing elevon delta

Had an idea a while back to build a delta wing with the elevons built within the wing structure rather than on the trailing edge. I haven't investigated the effects of the in-wing elevons on aircraft performance but the maiden flight turned out smooth and effortless. It takes a little more control surface authority than usual but that is the only negative I have noticed so far. I really need to fly the plane more then remove the trailing edge of the plane and restore normal elevon function and compare the flight characteristics. If anything, it looks cool and the airframe structure seems a bit more robust.
I modeled the delta originally on the 1B1M delta here in the forum, added a step to increase rigidity, added a vinyl vertical stabilizer (not entirely vertical so don't know what to call it - sinusoidal stabilizer?), a couple of chop stick nose gaurds, and the internal (jailed? cloistered?) elevons. Used dollar store type foam board. Around 350 grams, 900 mah lipo.

The plane is underpowered so will replace 13 gram 2200kv and 5 inch prop with 1800kv and bigger prop but even now if flies pretty sweetly.

In the video notice the eclipse of the sun provided by a keychain hatcam.

Update 4/12: much as I like this little plane, I need the electrics to do another quick project then will come back to this one. Need to order new motor for this one.

Update 4/15: put in 1800kv motor and 7 inch prop and it flies much longer. Forgot to set throws longer so had to put radio at 100% throws to get it to come back down. Will put on larger vertical stabilizer to see what effect it has.
