RealFlight will then automatically hide the NavGuide item from the gadget
that doesn't relate to the currently selected aircraft.
As the name suggest, the Gadget Text allows you to set the font size of the
text on the NavGuide to either Small or Large.
Restore Defaults-
The Restore Defaults button returns all NavGuides to their default values
and options.
Radio Mode (gadget only)-
This option allows you to change the Mode in which the on-screen radio is displayed.
For example, if you prefer to fly with the throttle and rudder on the left stick, and
ailerons and elevator on the right stick, then you fly Mode 2. Some modelers prefer
Mode 1. In this mode, the left stick controls the rudder and elevator; the right stick
controls the throttle and ailerons.
Whichever mode you fly, you will want the on-screen radio to match. Select Radio
Mode (gadget only) to show the list of available radio modes. Click the mode that is
appropriate for you.
