Hello,
as I keep progressing with my skills and my knowledge on the quadcopter world, I have a question.
At first I want to note that my quadcopter setup is:
DJI F450 frame
DJI E310 tuned propulsion kit ( 2312 motor, 420S ESC, 9450 props)
APM v2.8 flight controller with external gps/compass module
Installed power module
Multistar 10000mah 4S 10C battery
TURNIGY 9XR radio with FRsky DJT transmitter and V8FRii receiver
As you can see in my video, my Voltage indication fluctuates a lot between 14,2V and 16,5V. I have already calibrated the voltage reading of my power module and initially, (before arming the copter) my voltage indication is similar to the value that my multimeter shows.. In this video I am just having the quadcopter in ground without props and I was just giving a bit of throttle (about 25%) to see the behavior of voltage. Is this fluctuation normal ?? Shouldn't my voltage indication be more steady ???
Thank you for your help,

UPDATE: I discovered that this fluctuation in Voltage happens when I connect Mission Planner with the APM using the telemetry radio (http://www.hobbyking.com/hobbyking/store/__76950__HKPilot_500mW_Tra...)
However, if I leave the telemetry radio module attached to the APM but I connect Mission Planner with the APM using the usb cable, the Voltage fluctuations that I see in the status are around 0.3V..
So why does this happen ??? Please help....
