Stability testing

Stability testing: Something I could have done two months ago in two hours but for some reason didn't do it.

So I finally decided to do them, and here are my results. I'll start with the aircraft (Abi) without the vertical stabilizers. I could probably just give you a video and let you decide for yourself, but there's no reason to waste that much time. There's only one conclusion

It was a disaster. 

The wing extenders barely helped with yaw stability. I felt like i was in Tokyo drift trying to fly that plane around. Once the wind died down yaw stabilized a little, but was still off. It's obviously better than a pure plank flying wing, but obviously still very bad. 

After i slapped on some vertical stabilizer, it was perfect, stable, and everything I could ask for. Yaw was stable. Roll, pitch, all stable. Here's something else; I'm still in High school, so i'm not very "in-depth" of aeronautics. Some things i still do not know how to fix/improve, but somehow the stall characteristics on this plane is beautiful. Full up and the nose just pitches down and stabilizes. No tip stalling, thank god.

Here's the video that goes into some detail:
