I had something strange happen last weekend. This is my Protos Max V2 using a HW160HV ESC and Spirit gov. About one minute into the flight I lost power to the motor. I didn't know what was going on so I just landed out in the field. I then noticed it was slowly spooling back up so I hit throttle cut. I flew the heli four more times, very carefully, and did not have any strange behavior. In the plot below four lines are plotted: RPM, SC (throttle cut) and SH (throttle hold). The value of my SC and SF switches are shown in the plot, so you can see that I did not accidentally hit either of these switches. Also shown is PWM, which clearly shows I lost throttle signal for some reason. The plot also shows it going back into slow-start spoolup as I observed. Not sure if this is related to the telemetry issue I'm seeing with the Castle ESC's (different topic), but I thought I would bring it up because I cannot see any other reason for this to happen.
