FlySight case with 720mAh Li-Po battery

I had a bigger Li-Po battery lying around than the original FlySight uses and realized the box would only have to be slightly bigger to fit it, so I made a new version that fit the bigger battery.

A quick test shows that my FlySight runs 3.5 hours on the regular battery (Bionics Avionics states 2.5-3.5 hours, so not bad!), with the bigger battery it runs 13.5 hours per charge.
This mod will obviously void your warranty. I just couldn't help myself.
