I just installed a pixracer running 3.4.6 into a new Quadcopter and am finding now on every boot, I initially get a Bad Gyro Health alarm. It continues to warn me and the message stays on the Mission Planner screen. The quad eventually passes all the checks and lets me arm and I can fly fine. Once I arm the message disappears. I haven’t fully tested all the flight modes yet but Alt Hold seems to be fine. I have the same version of pixracer in a plane running 3.7.1 and I don’t get these alarms on the other pixracer. I don’t know if I have a bad board or if this is an indication that an older bug re-appeared. I enabled logging while disarmed so that I could get a log of the status. I don’t see anything in the log to indicate a problem but hopefully someone that knows can take a look and see.
