Davekyn,
TKS for explanation a details.
Indeed moisture, temperature and hight over sea level play an important role in lifting.
Being the more the worst in all of 3.
Here i have a PV2+ out of the stock and Galaxy S4 with Vision+ Utility Pro for recording telemetry.
Mainly flying in the middle o a big city (São Paulo - Brazil), where obviously the bird is prone to suffer all kind of RF interferences so i am far away of getting this kind a performance as yours.
But an very interesting positive point is that i use to fly the bird in a park just one bloch of my home allowing me to fly every time that i want (when wheather colaborates and i have time to do so)
At the weekends ... probably 3 times four batteries runs at a day.
Can't fly mutch high because this area is a helicopters normal local path and they fly at 1000ft to 1300ft
and PV2+ takes an eterity to descend ....
Flying at the park can be seen at :

Best regards and lots of happy and succsessful flys. Juan
