Light Frame for Nano QX

I tried to make a frame for the Blade Nano QX that is lighter as the original one. So that it may be faster and more agile.

Place the flight controller with a double sided tape in the center of the frame. The tape should be around 1.7mm thick.

The stock and most aftermarket batteries fit the holder tightly. A few others are a loose fit but stay in it.

Until now it does fly but wobbles in the air. If someone has an idea how to fix this let me know. I would appreciate it.
