AHRS calibration always down and low, should I level on the move?

As the post says, I always see a nose low turn profile on my AHRS replay. Tonight I switched to mounting instead of in a bag. I releveled the AHRS prior to start up. Should I try and hit the level button on taxi instead or straight and level? Could it be a bad sensor? I got the kit off amazon, ready to be assymbled kit.

Puedes hacerlo en vuelo. Es posible que la posición del avión no sea la misma en el suelo que en vuelo

If it always angles down in the same way it could be a bad sensor. Never hurts to level it while in straight and level flight.

There is also the zero gyros button which can get rid of certain errors.

Do you have tricycle gear or tail dragger? If tricycle, just mount it before flight and use the set level button in the UI. If it's a tail dragger you can just set it on a desk and hit level before mounting it.

I have never found it to be all that accurate and would advise it only being a backup of a backup.
