The graphics above show the stick command to bring up the OSD menu. The stick command is: throttle
centered, yaw left, pitch forward. The exact stick command therefore depends on which mode your
transmitter sticks are in.
In the OSD menu, use pitch up/down to move the cursor
between menu items. When a menu option has a > symbol
to the right of it, this indicates that it contains a sub-menu.
Roll-right will enter the sub-menu. For example, in the
screen to the right, moving the cursor to “Features” and
then moving the roll stick to the right will enter the
“Features” sub-menu.
