I am installing an Eagle A3 Pro SE 3 Axis Airplane Gyro into my tail dragger, Parkzone Se 5a. The instructions make no mention if the gyro board must be level with the ground or must I level the plane (i.e. raise the tail until it is level) before connecting the battery so the gyro can initialize? I know that I must mount it so that it is facing forward. It seems to me that when I mount the gyro board, that it is level with the ground while the tail is on the ground. Thanks.

It has to initialize with the wings level, that will be its level reference in flight.

Thanks. I was leaning strongly to that conclusion. Thanks again.
