Hello,
The calibration procedure should be the same. It concerns the IMU
part that is now common to fixed wing and rotorcraft.

Looking at the Messages for the "IMU_ACCEL_RAW" the
"int32 az (adc)" value hovers around -260, which I'm guessing
means it has not been calibrated.
I was looking over the ImuCalibration page,
but it looked like it was for rotorcraft. Can I use the
calibration scripts suggested on this page for a fixedwing IMU?
Are there other ways to manually calibrate the three components
I am using (l3g4200, adxl345, and hmc5843)?

Dear Blake,
How did you calibrate your IMU? Did you look at the
messages to see if your accelerometer and gyro's are
looking correct (accelerometers should measure -9.81
m/s2).
Choosing another ahrs filter will give the same problems
if your calibration is not good enough.

Hello,
I am having some issues with the DCM AHRS
setup for the PPZUAV IMU. The attitude value
will not increase past + or - 10deg no matter
how I hold the autopilot.
It might be important to note that I have
edited the PPZUAV setup to use a l3g4200 gyro
instead of the itg3200.
Can someone advice me on how to configure the
ahrs correctly?
As a side note, are there any other imu
filtering options?
Thank you.
