I’m facing a strange problem with my home-built quad.
I have a pixracer board with arducopter.
I don’t know what I did, but after some tweaking I can’t arm anymore the motors and I continuously get a RED WARING message on the HUD: “NO changshenbo”.
Since I can’t find any reference to this anywhere, I decided to ask here fr support.
Could I ask a favor unrelated to your issue? Could you post a screen shot of the HW ID screen after connecting to that Flight Controller? There seems to be some PixRacer clones around with only one IMU and I’m curious if you have one. I’m just interested as this question came up recently.
