This is an introductory video for setting up first level voltage production for the DJI Naza using the Naza Assistant. It also goes through the steps necessary to calculate your line loss voltage.
After some initial experimentation I've found that my ideal settings for a 2200mA 3S Lipo are:
No Load = 10.5V
Loss = 0.5V
Loaded = 10.0V
My quad specs are DJI F450 Frame, 950kV iPower motors, 30A ESCs, 10x4.5 props, and DJI Naza flight controller. The quad weighs 2.3lbs.
Here is a link to the Google doc that shows my no load voltage after each minute of flight. This is what I used to come up with what I thought was a good value for a no load voltage:
I'll post a follow-up video for setting up second level voltage protection next.
