It flies! Thanks!

So I've read a lot of tutorials about making planes, but I can't seem to be able to make one work... Here is one I tried to make. I try putting moving the center of lift closer or further from the center of mass, but can't find any spot that works (either the plane doesn't take off, or it spins upward). I'm sure there is some other conceptual thing I'm missing, buy I don't know what. Thanks!
