• Push down on the appropriate digital trim button on the transmitter for the control
you would like to change the direction of. For example:
Top elevator trim button—elevator channel normal
Bottom elevator trim button—elevator channel reversed
Left aileron trim button—aileron channel normal
Right aileron trim button—aileron channel reversed
• Continue to hold the appropriate trim button while turning the transmitter on.
• Hold the digital trim button down for approximately five seconds, until a series of
beeps/tones are heard confirming the selection.
• Connect the battery to the 5-in-1 and complete the flight control test, confirming
that all controls are operating in the correct directions.
If you decide to use an E-flite LP5DSM or HP6DSM transmitter, please position your
channel reversal dip switches as follows:
LP5DSM Transmitter
HP6DSM Transmitter
Note: Keep a record of the existing settings in case you want to go back and fly
your other aircraft.
Once you’ve reconfirmed the flight control directions, all controls should be
functioning properly. However, if you continue to encounter any problems with
your Blade mSR responding properly to the transmitter, do not fly. Call the Horizon
Support Team at 1-877-504-0233.
If you’ve confirmed proper control operation of your Blade mSR, continue reading the
manual prior to attempting to fly the helicopter.
Note: Attempting to fly the helicopter without completely reading the manual may
cause injury to yourself and people in the vicinity, as well as damage to
the helicopter.
Important Channel 5 Information
• Channel 5 affects rate settings of the 5-in-1 Control Unit.
• If using the stock MLP4DSM Transmitter, this information is not pertinent.
• If using an LP5DSM or HP6DSM Transmitter, please turn the Channel 5 knob
clockwise completely.
• If using any other DSM2 compatible transmitter, please ensure Channel 5 is set to
default servo reversal and the switch or knob is set to a position that allows full
travel control.
Note: This can easily be tested by inducing full cyclic (Aileron/Elevator) input and
moving the switch or knob. There’s approximately 15% less servo travel
depending on what position Channel 5 is in.
5-in-1 Control Unit Description, Arming and Motor Control Test
The unique 5-in-1 Control Unit installed on your Blade mSR is a lightweight
combination of main motor and tail motor electronic speed controls, mixer, gyro,
servos and Spektrum DSM2 compatible receiver. The 5-in-1 unit is also equipped
with a BLUE status indicator LED.
The following checklist contains the steps you must follow to ensure proper arming
and operation of the 5-in-1 unit, as well as proper motor response.
• Each time before you fly you should ALWAYS turn the transmitter on and
set at least 2 feet away from the aircraft before connecting the flight
battery to the 5-in-1 unit. Never connect the flight battery to the 5-in-1
unit before powering the transmitter on first. After each flight, be sure
that you always disconnect the flight battery from the 5-in-1 unit before
powering the transmitter off.
Note: The only time you should connect the flight battery to the 5-in-1
unit before powering the transmitter on is when you are binding
the receiver of the 5-in-1 unit to the transmitter. Please see the
Transmitter and Receiver Binding section of this manual for more
