PCB weight reduction

Just weighed the new PCB. It’s lighter!

The v2 PCB weighs 1.62g, which is 21% less than the v1’s 2.05g. This should make flight more stable and use less power, or at least give us an extra 0.4g to for more sensors.

We went from a 31mil (0.031 inch) board thickness to a 20mil board thickness, which is why the board got lighter. Although the board thickness shrunk by about 35%, he board didn’t get 35% lighter because the non-filler material didn’t shrink (traces, etc).
