I’m running plane 3.5.2. Im using a 3dr power module. The voltage is calibrated correctly as given in the guide - http://ardupilot.org/copter/docs/common-power-module-configuration-in-mission-planner.html.
However, the current reading shows zero at all times. It fluctuates around 0.1A when throttle is idle and drops to zero when throttle is increased.
I have tried re calibrating the thing multiple times, and nothing seems to work.
got any ideas?
