I contact Hobby Eagle and they explained they modified
the software for greater rotation stability over the A3 Pro
previous version. They purposely increased the endpoints,
going from deactivated to 2D and from 2D to 3D for greater
stability in the air. I found the best way to set this gyro up
is to adjust the trim buttons on the front of the transmitter
to neutral, put subtrims at zero, then mechanically adjust
surfaces to neutral, then center the sticks. There should be
no movement switching from 2D to 3D on the ground .
