WARNING: Before proceeding further, remove the propeller and spinner from the motor shaft. Never attempt
to program the radio components, assemble the aircraft or perform maintenance of any kind without
removing the propeller. Serious injury could result if the motor starts inadvertently with the propeller still attached.
1. Ensure the flight battery is NOT connected to the aircraft.
2. Remove the screw (A) and spinner (B) from the spinner
backplate (C).
3. Remove the hex nut (D), propeller (E), and the spinner
backplate from the collet.
Installing the Transmitter Batteries (RTF)
CAUTION: NEVER remove the transmitter batteries while the model is
powered on. Loss of model control, damage or injury may occur.
CAUTION: If using rechargeable batteries, charge only rechargeable
batteries. Charging non-rechargeable batteries may cause the
batteries to burst, resulting in injury to persons and/or damage to property.
CAUTION: Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to national regulations.
1. Remove the battery cover from the bottom of the transmitter.
2. Install four AA batteries as shown.
3. Install the battery cover.
Turning the Transmitter ON and OFF

Transmitter Layout
Explanation of DXS Transmitter LEDs, Switches and Modes for the Apprentice.
Trainer/Bind/Panic Button : This button is used as both the trainer and
bind button as well as the Panic button for your Apprentice S 2. For complete
binding instructions, refer to the binding section below. When using the trainer
function, connect the trainer cord (SPM6805) into the trainer port in both
the instructor and the student transmitters. The instructor transmitter must
be powered ON and bound to the receiver. The student transmitter must be
powered OFF. Any time you press and hold the trainer button on the instructor,
it will give control authority to the student. Releasing the trainer button returns
control to the instructor.
IMPORTANT: The student transmitter must always have the same settings
as the instructor. See Flight Training section for setup of other Spektrum
transmitters.
Hi/Lo Rate Switch: This switch supports high and low rate functions on
aileron, elevator and rudder channels. In the upper, or "HI" position, servo
travel is 100% on these channels. In the lower, or "LO," position, servo travel
decreases to 70%. This switch lets you quickly change control rates from
high for aggressive maneuvers to low for smooth, precise maneuvers. When
learning to fly, use low rate.
Safe Mode Switch : This switch is used to select the SAFE Flight mode. For
other conventional receivers, this switch controls a servo connected to the
Channel 5/Gear port.
Throttle Cut Switch : This switch is used to arm and disarm the throttle control.
LEDs : Flashing with beeps Bind mode when Trainer (Bind) switch is held and
the transmitter is powered on (see Binding instructions). Pulsates with one low
tone beep every 2 seconds (when transmitter battery voltage drops below 4.7
volts). Replace the batteries immediately. If this happens while flying, land your
aircraft as soon and as safely as possible.
