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.
Push 3D performance to the limits by giving you more power
when you need it while keeping the rotor speed constant at other
times.
Give you consistent flight feel from start to finish; unlike some ESC
governors, RPM does not drop as battery voltage drops (as long
battery can provide enough power).
Takes the Guesswork out of setting up Throttle Curves.
Check the motor connection to the ESC, reconnect them if
necessary. Check your battery. Full charged? Replace battery if
necessary. Try another receiver.
Disconnect battery and then reconnect battery and start at step
2.0 again.
Motor does not shut off with throttle hold set throttle hold
position to 0%.
After initiating esc with throttle hold on motor spins slowly when
turned off > Set throttle hold to 0%.

7.0 Lights and Sounds
8.0 Trouble Shooting
9.0 Governor Function for helicopters
Your ESC will emit different lights and sounds according to the
function it is applying below is a table of the following condi-
tions:
Scorpion has developed a inbuilt governor that uses complex mathematics and
fast processor speeds to provide one of the most user friendly and advanced
governors on the market today.
Please follow the below steps to setup the governor on your ESC.
What it does
A Governor is designed to Govern the speed of your main rotor blades. In basic
terms this means that the ESC will try to keep the same rotor blade speed (set by
you) regardless of the amount of pitch on the main blades and load on the
motor. To do this the ESC tracks the motors speed and will automatically
increase or decrease the power to the motor to maintain constant rpm or
headspeed.
Before programming the governor you must perform the initial Setup in section
4.0 in this manual first.
No Signal from
receiver at startup
LED light will flash orange with constant 2
warning tone. If Using program card, the LED
will flash red and emit 3 beep tones then you
will enter setup mode.
Over temperature
during power up
(>60°C)
LED will be constant red with 2 beep warning
tone. To restart, disconnect power source, wait
for cool down then re-connect.
Over heat during
operation (>85°C)
Power reduced to half throttle, red LED will
flash. To reset throttle must be put into idle
position.
Power on low
voltage warning
LED will flash red quickly with beep warning
tone when voltage is low than preset cut-off
voltage.
Low voltage cut
warning
When voltage is lower than preset cut off
voltage, red LED will flash rapidly red.
Over Amp Protection
Is only activated at over 50% throttle during
over-amp protection, LED will flash red rapidly.
Governor Limit
If governor reaches 100% throttle, orange LED
light turn on.
Soft start indication
Orange LED light will turn off automatically
when soft start has been deactivated.
Loss of signal during
operation
LED will flash red with a 2 beep warning tone.
What it allows you to do
Programming the Governor
Modes 1-3 will not compensate for no load conditions. For example if you are
hovering and pitch down (negative pitch) the power needed to keep the motor
at the set RPM will be less the ESC will allow the rotor blades to fall the to right
speed under their own weight.
Modes 4-6 will compensate for no load conditions. For Example if you are
hovering and pitch down (negative pitch) the power needed to keep the motor
at the set RPM will be less the ESC will apply a slight amount of brake to will
allow the rotor blades to fall the to right quickly.

Startup Procedure (Read all steps before attempting)
Insure you have the IR Receiver Plugged in Refer to Section 5.0 of this
manual
Remove the motor pinion
Power Receiver
Power ESC
Move Switch of IR Receiver to Program mode see section 5.0
3 beeps will sound you are now in program mode
Press SS > 2 > Enter. 2 beeps will sound confirming SS 2 mode selected

Set your throttle hold position in your radio to 0%
In your radio you need to set your throttle curves to the % of throttle you
wish to operate your governor at. It is a good idea to use a head speed
calculator first to find out an estimated target HS you wish to achieve.
Once you have estimated the amount of throttle needed to achieve your
target head speed enter it into a throttle curve so that it is the same % of
throttle across the entire range eg I would like 80% throttle for all points
across the curve you should have flat line at 80%. You can only select values
from 50-90% throttle.
You can have different throttle values for each flight mode and you can flick
between them in mid flight with no effect on the governor as long as it has
been set properly at initial startup.

Turn on your radio and place throttle hold switch to ON
Power your Receiver
Plug your ESC to the main power battery
Wait for it to arm (4 beeps di di dee do)
Select the flight mode you wish to fly in
Insure your blades are at 0 deg pitch (If your blades are not at 0 deg your
governor will not set itself properly)
Turn throttle hold switch OFF
Soft start will initiate – Depending on the soft start duration you have set
10, 15 or 20 seconds wait on this amount of time for the blades to stabilize
speed. (The LED will glow orange during startup and will turn off once the
headspeed has been set and stabilized).
Measure the blade speed at 0 deg pitch with a tachometer or similar device
to see if you are achieving the desired headspeed.
If the Head speed is to high go back into your throttle curve and reduce the
throttle or if it is too low, increase your throttle curve.
Auto Rotation Bail out Feature for Soft start and Governor modes
If you attempt an autorotation once you have switched your throttle hold
switch you have a 12 second time window where if you feel you cannot make
the auto rotation you can switch the throttle hold off and your helicopter will
instantly regain throttle to either your stick position in Soft start mode or your
set governor throttle %.
