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.

1.0 Connecting your ESC
* Please refer to the diagram on Page 3 to properly connect your ESC.
1.3
Connect to your receiver / External Governor
Connect the receiver lead (Master: the three colored small wires:
brown, red, yellow) with a red plastic connector on the end to the
throttle channel on your receiver and connect the black plastic
connector (Slave) to an external governor, unplug the yellow
(signal) wire if you do not use the RPM signal for telemetry or
external govenor (e.g. VBar govenor). If you have external battery
that you may need to disable the bec in programing. If you do not
use the RPM signal for telemetry or external govenor (e.g. VBar
govenor) just leave it unplugged.
1.1
Add your battery connector
You must attach a quality battery connector of your choice to the
red (positive) and black (negative) power wires. Solder the battery
connector to the wires. ENSURE THAT THE POLARITY IS CORRECT
(red wire (positive) to battery red wire (positive), black wire
(negative) to battery black wire (negative)). Follow the
instructions provided with the battery connector.
1.2
Connect Motor to ESC
We recommend using bullet connectors to connect your ESC to
your motor as most of the 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. Once connected DO NOT
allow any exposed wire or connectors to contact each other!
Ensure that a proper insulation material (such as heat shrink) is
around each of the three wires. Failure to do so will cause the ESC
to malfunction and void your warranty.
1.4
Mounting the ESC
Mount the ESC with the Heatsink side of the controller facing
outward. We recommend using a “Scorpion Fastening Strap” to
attach the ESC to the airframe for easy removal. Double sided
tape is acceptable for mounting as well. If zip ties are used, do not
place them over any of the components on the ESC. Instead, zip
tie around the metal heat sink, leaving some slack to allow some
movement.
1.5
Tribunus ESC BEC
For safety reasons we recommend using a Scorpion backup
guard or a backup battery. The Backup guard can be used on any
BEC voltage from 5.1 to 8.1V. If the BEC voltage is set to 7.1V or
8.1V use a 2S LiPo. Connect the BEC backup parallel to the
receiver or Flybarless system. Make sure that the Backup guard is
charged or the 2S LiPo battery voltage matches to the set BEC
Voltage before every flight. Also make sure all used RC-
components are designed to run at the set BEC voltage. On the
slave cable remove the signal cable when it use for extra bec only.
The induction voltage cause by servos will activate the
protection of the BEC, we highly recommend the BEC voltage set
to 7.1V or below to avoid this.
