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.

The Scorpion Commander Series of ESC’s are made up of two
different types of ESC’s classified by the maximum voltage they

manual.

You must attach a quality battery connector of your choice to
the red (+) and black (-) power wires. Solder the battery connec-
tor 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 conven-
ient to temporarily connect the motor leads to the ESC and test
for proper rotation before you permanently solder them. 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. The OPTO Speed Controller does not supply
power to your receiver.

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 compo-
nents on the ESC. Instead, zip tie around the motor and battery
wires, leaving some slack to allow for movement. The OPTO
Series have mounts that allow you to screw the ESC into a frame
or something similar.
