The GPS mast can be flipped up and down. When installing and uninstalling a battery in the top compartment, it is helpful if the GPS is in the down position.

The GPS mast must also be in the down position to fit in the case.

Before installing propellers and before and during flight, the GPS needs to be up in order to

prevent the propellers from damaging the GPS and to more easily acquire GPS signal.
