Pixhawk 2.4.6 with Arducopter 3.2.1 loaded with Mission Planner
The two motors on the left is spinning faster than the two on the right resulting in the quadcopter flipping over to the right on take-off.
I have done the following:
Tested all motors and ESC’s
Swopped out the motors and ESC’s
Checked motor layout (top right = 1, bottom right = 4, bottom left = 2, top left = 3)
Checked motors are spinning in the correct direction
Checked props are correct
Reloaded Arducopter
Calibrated ESC’s (one by one and all together with Pixhawk)
Calibrated the Radio
Calibrated compass and accelerometer
Did the motor test
Check that the quadcopter is level on Mission planner
I have two Pixhawk both doing the same (they are brand new)
Using it with a s.bus receiver
I have attached the log file can anyone help me with this problem.

Hi, Thanks it was the RCMAP that was making it flip
It's because you are using RCMAP. This doesn't work in 3.2.1 - upgrade to 3.3 and you will be fine.
I should point out that the upgrade needs to be to 3.3-rc6 or later, which is not out yet. So if you want it now you will need to build it yourself.
Test: IMU Mismatch = GOOD - (Mismatch: 0.26, WARN: 0.75, FAIL: 1.50)
Test: Compass = GOOD - mag_field interference within limits (4.51%)
I'm not sure, but it looks like your radio might be a part of the problem. I'm not familiar with the pixihawk logs, but it looks like the radio error might have been caused by peaking radio waves? I'm not sure what of UBX ofsQ is, but that's what's those peaks are, and the red line is radio interference. The only large shocks from the gyros I could see lined up after the radio interference was leveling out, and I'm not sure what the acceptable levels of radio interference are. Hope that this will give you some theories to work out.
