unexpectedly and cause serious injuries. Always treat
them with necessary respect. Keep the propeller
away from your body and others at all times.
We suggest that you remove the propeller when you
are working on the plane with the battery connected.
We suggest that you remove the pinion when
working on a Helicopter with the battery connected

Battery Eliminator Circuit (BEC)
The Commander 26V SBEC series feature a inbuilt switching BEC that will
convert the voltage from your battery pack to 5.7 volts to power your
receiver and servos. The Commander SBEC will deliver 3 amps of continuous
current with 4 amp bursts. With a Switching type BEC, you do not need to
de-rate the BEC as the input voltage increases. The full 3 amps of BEC
current is available for any input between 2-cell and 6-cell Li-Po operation.
1.0 Connecting your ESC
*for larger picture refer to back of this manual
1.1. Add your battery connector
You must attach a quality battery connector of your choice to
the red (+) and black (-) power wires. Solder the battery
connector to the wires. ENSURE THAT THE POLARITY IS
CORRECT (red wire to battery red wire, black wire to battery
black wire). Follow the instructions provided with the battery
connector.
1.2 Connect Motor to ESC
Cut the three (red, yellow & black) motor wires coming off
the ESC to the length you require. We recommend using
bullet connectors to connect your esc to your motor as
scorpion motors come with pre-installed bullet connectors
that include a female set for your ESC. Solder the
corresponding connectors for your motor to the wires coming
from the ESC, or solder the motor wires directly to the motor
leads. You may find it convenient to temporarily connect the
motor leads to the ESC and test for proper rotation before
you permanently solder them. See “Reversing Rotation”
below. Once connected DO NOT allow any exposed wire or
connectors to contact each other, insure that proper
insulation around each of the three wires is achieved, Heat
shrink is the best material for this job.
1.3 Connect to your receiver
Connect the receiver lead (the three colored small wires with
a black plastic connector on the end) to the throttle channel
on your receiver. Do not connect a receiver battery pack to
the receiver, as the Scorpion ESC will supply power to the
receiver and servos through the receiver connector.
1.4 Reversing Rotation (if necessary)
Bench test the motor and speed control after the
connections are made to determine the rotation of the motor.
To change the rotation of the motor, swap ANY two motor
wire connections, or use the scorpion programming card
included with your esc to change the rotation direction.
1.5 Mounting the ESC
Mount the ESC with the Heatsink side of the controller facing
outward. We recommend using Velcro to attach the ESC to
the airframe for easy removal. Double sided tape is also
acceptable. If zip ties are used, do not place them over any of
the components on the ESC. Instead, zip tie around the
motor and battery wires, leaving some slack to allow for
movement.
2.0 Using your scorpion ESC
2.1 Ensure that the ESC is connected to the proper channel
on your receiver.
2.2 Turn your transmitter ON and set the throttle stick to
zero throttle.
2.3 Connect the main power battery to the speed controller.
2.4 The ESC will beep the motor (4 tones) to indicate that it
is armed.

The ESC will not provide any power to the motor, if the throttle
stick is anywhere higher then zero throttle when the main battery
is plugged in. To arm the esc ready for use you, You must move
the throttle stick to zero then disconnect and re connected the
battery.
Always power your radio transmitter before powering up the
receiver and/or the ESC. Some receivers with failsafe features or
Spektrum receiver units that are not bound on receiver power up
are entirely capable of causing the arming sequence to occur and
command the ESC to drive the motor. Always keep the aircraft
restrained and clear of body parts when the ESC is powered.
If your ESC cannot sense any radio signal it will beep the motor
and flash orange on the LED continuously
3.0 Scorpion SBEC features
ALL of the Scorpion 26V SBEC programming features are
available though the use of the ESC programming card
included with your ESC. So there is NO need to purchase any
other cables or cards to allow you to program your ESC
properly
Scorpion ESC’s come with default or factory settings which
are recommended for most applications. Programming
options can be changed at the discretion of the user. See
section 6.0 for programming instructions
Features:
Safe Power up To arm the controller, the throttle must be
held in the “Brake/Zero” position (all the way
down). If throttle is not at zero at startup, the ESC
will not provide any power to the motor regardless
of where the throttle stick is positioned when first
powered up.
Loss of signal
(fail safe) The Scorpion will stop the motor as a safety feature when the throttle signal is lost or
corrupt for 3 seconds. If a signal is regained the
user will have instant control again.
LED The LED is used for programming/startup
confirmation of your scorpion esc. Once armed
the LED can be set to give an indication of low
battery conditions
Low Voltage Cutoff You can choose for your ESC to stop or reduce
power when the input battery voltage drops to a
preset/programmed cutoff voltage.
Current Limiting Amp output limit, the output is rated at 10% over
the rated Amp. At approximately 10% over the
rated Amps it will automatically limit the output to
the motor, as long as the motor is not rated too
much over the ESC spec limits, this safety
mechanism will prevent a over load to the ESC but
if you install a motor for example rated at 100
amp on a ESC that are rated for only 60Amp, this
mechanism will not work properly due to the
instant surge of power demand from the motor, it
may shutdown too early or simply fry the ESC, the
only solution to this is to never use a Motor that
has a rating bigger then the ESC, don’t even think
you can use it if you run the motor at a slower
RPM or load, it will not work!!
Thermal Protection At 95 degree C, the ESC will slowdown the power
output to the motor by 50% ( the on board LED
will flash red), to re initiate full throttle you need
to move the throttle stick to idle position and then
the ESC will resume normal output once you
throttle up again. If your ESC is over 60deg on
startup it will not arm red LED will flash and a DI
DI DI sound will be played.
Brake Stops rotation of the motor when the
throttle signal is moved to the lowest
position.
Throttle Airplane, Car and Heli modes come pre
programmed and can be selected by the user
Electronic timing Manual settings that may improve the efficiency of
the system for some motors are available. The
standard Scorpion setting is to automatically
detect and adjust for the motor it is driving.
4.0 Initial setup
You MUST perform throttle range setup before the first use of
the ESC. Remove propeller/pinion from motor while
performing initial throttle range setup.
4.1 Throttle range setup (full throttle and stop)
4.2 Turn on transmitter and set throttle to maximum
position
4.3 Connect battery to ESC. After approximately 2
seconds, the LED flashes rapidly, then 1 second after
you will hear 2 beeps from the motor confirming the
maximum throttle position has been set. (If at this
time, you leave the throttle stick at maximum
position for over 10 seconds, the ESC will reset itself
to Factory default throttle setting)
4.4 Move throttle to minimum position within 10 seconds
and hold throttle at minimum position, the LED
flashes slowly for 1 second. Then you will hear 2
beeps (1 KHZ tone) indicating minimum throttle
position is set and confirmed. You only need to do
this once as throttle range will be stored in the
memory of the speed controller. You can reset the
throttle range by performing steps 1.1 to 1.3 again
5.0 Connecting your Scorpion
SBEC to the programming card
Your Scorpion SBEC is programmed using the Infrared (IR)
Program card and Receiver included with this ESC.
First you must connect your IR Receiver to your ESC
Ensure the brown wire from your esc is facing outwards
5.1 Once you have plugged in the IR Receiver push the
switch across to IRS.
5.2 Now connect a battery to the ESC. Your motor will emit 3
beeps and the LED will flash 3 times red.
5.3 Your IR Receiver is now ready to receive a signal from
the program card.
please note that IR will be interfered in direct sunlight so to
program your model we suggest doing it indoors in the shade out
of direct sunlight
before flying you will need to place the switch back to PPM mode

6.0 Using the Programming Card
All parameters of the esc can be changed via the
program card.
To program any function on the card you must follow the
following procedure:
6.1 Press a function button
6.2 enter a numeric value
6.3 Enter to complete
Example Low Voltage Cut to enter 9.5V Press “LVC” Press
“0” Press “9” Press “5” then “ENTER” If successful a DI
DOO sound will come from the motor and the LED will
Flash RED. An invalid option will not get any confirmation
sound from the motor and the LED will not flash
Please note that there is a time limit from when you press a
function button the numeric values and enter if you go over this
time limit no sound of flashes will come from the esc

Soft start indication Orange LED light will turn off automatically when
soft start has been deactivated.

8.0 Trouble Shooting
If you hear a pulsed warning tone and/or see a continuous
orange flashing LED after powering up the ESC:
Check your transmitter. Is it on? If yes.
Check that your throttle is at its minimum position. Your esc
will not arm if you throttle is anything other then zero at
startup
Check the ESC servo connection? Connection good? If yes.
Check the motor connection to the ESC, reconnect them if
necessary.
Check your battery. Fully charged? Replace battery if
necessary.
Try another receiver.
Disconnect battery and then reconnect battery and start at
