Help me please,
My F550 with E300kit, Naza-M V2, Arris CM3000Pro, FVP, mini IOSD, ROC 4S 5800mah 30c 14.8V. The weight with battery 2490g.
I start with 16.8V full charge and after 3,56 minutes the power drops (in air) to 14.8V and i need to land, then on the flor the power raize up to 15.5V...
Is any problem with configuration, with the Naza, or with the Motors or ESC??

Thanks in advance for your time,


Best regards,

It's normal that voltage0 rise back.
Does it have anything to do with the electrochemical polarization?

Voltage of the Lipo will drop fastly and then stay at a stable level.
During the discharging curves of 4S batteries, 14.8V(3.7V*4) can be the stabilize voltage~

Don't panic in 14,8V for 4s cell battery. Continue to fly until 14,1V, then land

How is the Arris CM3000Pro?  Is there variable speed control available for the pan and tilt and is it smooth?
