NanoPhan Rocks!!!
The new battery configuration made a huge positive difference, combined with the longer fan body.
I also upgraded the ESC by adding a mini heatsink on it, to handle the extra weight (originally it is a superlight multirotor ESC ).
Even though I built this for indoors, I felt comfortable enough to test it outdoors. There is a slight steady wind but it didn’t stop me. This is only a balance and flight time test and I just kept hovering against a headwind but I felt comfortable enough to take it around the park if I wanted.
The flight time is a whopping +3 minutes!!!
