After completing setup with everything finally working perfect on the OSD, I was preparing for first flight and noted that the current sensor is stuck on 0.5 amps and will not move from that no matter how much throttle through the motor. I am careful to wait the full period that it is suppose to calibrate and I've verified that it is plugged in correctly and to the right place. I've also verified that the correct sensor is listed in the OSD menu. Any ideas or settings that I"m missing or does it look like it's doa? Thanks!
