Arduplane 3.8.0 Beta 3 with PixRacer - betatesting

I have a problem with the beta 3 of ArduPlane 3.8.0.
I have a PixRacer.

This is the video of the problem:

I also have another problem: if I disable the prearmcheck, and I arm the plane in MANUAL I can not start the only one motor that I have. I do not knwo why. In this case I can not check if the motor works right or not.

Best regards,

Here we have te log!

I have found why I can’t start the motor: I forgot to calibrate ESC.
Now I can start the motor in manual mode with prearm check de-activated.

But I still have the AHRS problem :frowning:
