Ha, Ha! I was just putting it through its paces. It's actually a smooth stable flyer but with the camera on the nose it looks a bit crazy.

I've tried with a 1.3 and a 1.0 nanotech 3S battery , to try and change up the CG. With the 1.3 it appears to be balanced and glides well. But with power it is a lawn dart.
I would check to be sure your motor mount is on straight. It should not be off center or angled at all.
