FlySight case with 720mAh Li-Po battery

I had a spare Li-Po battery larger than the FlySight's original one, so I decided to create a new version that could accommodate it by only slightly enlarging the box. A brief test revealed that my FlySight operates for 3.5 hours on its standard battery (Bionics Avionics estimates 2.5-3.5 hours, which is more than acceptable), while with the bigger battery it runs continuously for 13.5 hours per charge. This modification will, of course, nullify any existing warranty. I couldn't resist making this upgrade.
