My Quad spins and EKF attitude is bad

Hi All,

My Quad is F450 frame, LiPo 3S 6500 mAH 60C, 10" propeller , MPU9250, QMC5883l, M10 GPS, OBAL flight controller,

I calibrated the Quad and seems everything was fine.

when I tried to fly it starts to spin (Yaw) before it leave the ground then it gave EKF issues so I stopped it :

here is my Zipped logs :

can someone point me to a solution ? I am completely stuck.

MR spinning prior to takeoff typically indicates motors spinning wrong way. Use the Methodic Configurator to avoid such basic mistakes.

You need to do more than calibrate it before an initial flight. What are you using for an RC Controller? Looks bad:

I see your point. I am using “flysky fs-i6x” and I agree that the RC Inputs are the root-cause of the spin(Yaw). I will try to figure out the source of the issue.

do you have any guesses for the EKF issue ?
