FEATURES EXPLANATION

Trim Levers:

There is one trim lever associated with each primary function - throttle, rudder, elevator

and aileron.  The trim levers are used to correct any tracking problems of the airplane and
the idle setting of the engine.

When you set up the control linkages on a new airplane, the control surface trim levers

should be centered.  After flying and trimming the airplane, check the location of the control
surface trim levers.  If one or more is no longer centered, we suggest making adjustments to
the airplane’s control linkages, so that the trim levers can be recentered.

Control Stick Length Adjustment:

The length of the control sticks can be adjusted to suit

the user.  When lengthening the control sticks, verify that
the ends of the control sticks are still firmly secured in
place.  They should not be loose or they may come off.

Antenna:

The antenna is telescoping and should always be pulled out completely while flying.

Power LED:

The power LED glows red when the transmitter is turned on.

Servo Reversing Switches:

These switches allow you to electronically change the

direction the servos move.  Servo reversing is featured
on channels 1-4.  Double-check that each switch is firmly
pushed to one extreme or the other.  A small flat-blade
screwdriver works well for moving the switches.

Transmitter Battery Voltage Meter:

When the transmitter is turned on, the voltage meter

displays the status of the transmitter batteries.  If the
needle reads in the silver-colored area from 70-100, it’s
safe to fly.  If the needle reads in the red-colored area,
the transmitter batteries should be replaced.

Auxiliary Switch:

The auxiliary switch will operate a servo plugged into the channel 5 slot of your receiver.

This switch is most often used for retractable landing gear or flaps.  This switch can be used
for any function that requires a non-proportional action.
