Installing the Transmitter Batteries (RTF)
Replace the transmitter batteries when the
transmitter beeps.
Transmitter Setup (BNF)
Program your transmitter before attempting to bind or fl y
the helicopter. Transmitter programming values are shown
below for the Spektrum DX6i, DX7s, DX6, DX7, DX8, DX9
and DX18.
The fi les for models using Spektrum™ transmitters with
AirWare™ software are also available for download online
at www.spektrumrc.com.
Your helicopter is also compatible with Spektrum DXe radios
with software version 1.3 or higher. Use the directions below
to reverse channel 6, or use the appropriate programming
cable and the PC or mobile app to program the DXe. We
recommend downloading the Blade 120 S DXe model setup
available at www.spektrumrc.com.
DXe
To use the DXe transmitter with the Blade 120 S, channel 6 must be reversed.
To reverse channel 6:
1. While powering on the DXe, hold the left and right sticks in the top-inside corners
as shown.
2. Re-center the sticks after the transmitter beeps. The LED will fl ash slowly.
3. To select a channel to reverse, move the right stick to the left or right and allow it
to re-center. Move the stick to the right to select the next channel. Move the stick
to the left to select the previous channel. The LED will fl ash rapidly corresponding
to the channel selected, as shown in the table. Select channel 6.
4. To reverse the selected channel, move the right stick up or down. The LED will
change color to indicate the new channel direction.
The LED will fl ash Orange to indicate the channel is normal.
The LED will fl ash Red to indicate the channel is reversed.
5. To store the changes, power off the DXe.
CAUTION: During the subsequent power up, always verify the throttle
direction is correct and keep clear of the motor and rotor blades. Failure to do
so may result in injury or damage to the product.
If you are programming your DXe using the PC or mobile
app, make sure the "Transmitter Channels" value is set to
the default of 7. If for any reason this value is changed
to 9, the 120 S will bind to the DXe, but will not respond to
control inputs.
If your DXe was included in another Blade Ready To Fly (RTF)
helicopter, the transmitter software will have to be updated
using the appropriate programming cable and either the
PC or mobile app available at www.spektrumrc.com.
Please note, the switch confi guration used for DXe transmitters included with the Blade 230 S RTF and Micro AH-64
Apache RTF varies from the standard DXe layout.
After reversing channel 6, bind the transmitter and
helicopter normally.
Flight modes are controlled by the Flight Mode switch.
Panic Mode is controlled by the Bind/Panic/Trainer button.
Once bound, the LED in the helicopter should glow blue for
fl ight modes 0 and 1 (Stability, Low-Angle and High-Angle
Modes), and glow red for fl ight mode 2 (Agility mode).
If the LED glows blue in all three fl ight modes, channel 6
has not been reversed correctly. Use the directions above
to reverse channel 6.

1. Lower the throttle stick to the lowest position (A) and
center all trims.
2. Set the Flight Mode Switch to Stability Mode (FM0)
3. Power ON the transmitter (B).
4. Slide the fl ight battery fully into the mount of the helicopter frame (C).
5. Connect the power lead to the battery (D), noting the
correct polarity.
CAUTION: Connecting the battery to the control
board with reversed polarity will cause damage
to the control board, the battery or both. Damage caused
by incorrectly connecting the battery is not covered
under warranty.

6. Place the helicopter on a fl at
surface and leave it still until
the red LED changes to blue and glows solid, indicating
initialization is complete.
If the LED on the control board fl ashes rapidly, proceed
to the Transmitter and Receiver Binding section to bind
the helicopter and transmitter.
NOTICE: Do not allow the helicopter to move until the
LED on the control board is solid blue.
If you experience issues during initialization, refer to the
Troubleshooting Guide at the back of the manual.
CAUTION: Always disconnect the Li-Po battery
from the aircraft when not fl ying to avoid overdischarging the battery. Batteries discharged to a voltage
lower than the lowest approved voltage may become
damaged, resulting in loss of performance and potential
fi re when batteries are charged.
Transmitter and Receiver Binding
Your RTF transmitter comes prebound to the model. If you need to re-bind, follow the directions below.
MLP6DSM Binding Procedure (RTF)
1. Disconnect the fl ight battery from the helicopter.
2. Center all trims on your transmitter.
3. Power off the transmitter and move the throttle stick to the down/off position.
4. Connect the fl ight battery in the helicopter. The Blue LED on the control board fl ashes after 5 seconds.
5. When the Blue LED light is fl ashing, push in and hold down the left stick* while powering on the transmitter (you will hear a ‘click’).
6. Release the left stick. The transmitter will beep and the power LED will blink.
7. The helicopter is bound when the LED on the control board is solid blue (not blinking).
8. Disconnect the fl ight battery and power the transmitter off.
* The trigger switch may also be used for the binding procedure.
If you encounter problems, obey binding instructions and refer to the troubleshooting guide for other instructions. If needed, contact
the appropriate Horizon Product Support offi ce. For a list of compatible DSM
