SAFETY
Scorpion and their re-sellers are not responsible for
your use of this product, or any damage or injuries
you may cause or sustain as a result of it’s usage.
Understand that an electric motor that is connected
to a battery and speed control may start
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
Please observe all local laws regarding the flying of
remote control aircraft.
Never fly over others or near crowds.
Included in the BOX
1 x Scorpion SBEC ESC

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.
