80A Brushless Speed Controller
· We strongly recommend to calibrate the throttle range of transmitter when you first use the controller or
when using a new/different transmitter or receiver.
·When connecting the ESC to battery pack, please ensure the polarity is correct. Incorrect polarity may cause
permanent damage to the ESC and such damage is not covered by manufacturer’s WARRANTY.
·When you use the ESC, turn on the transmitter BEFORE powering on the receiver.
·When you finish the flying, power off the receiver BEFORE turning off the transmitter.
·The limiting current is set to the ‘standard mode’ in factory. It is suitable for use in most configurations.
Only experienced technicians can adjust this programming.
·In Governor Mode, the brake is always disabled and the soft cutoff is always active.
·Changing the PWM may cause the motor to heat ahead of time.
·Never disconnect the battery pack while the motor is running, as this could cause damage to the speed controller and/or motor.
·Connectors with low conductivity may cause erratic motor rotations or other unexpected
·If you do not use the BEC function of the ESC and are using a separate receiver pack or UBEC to power
receiver and servos instead, please disconnect the red wire from the ESC’s receiver lead.
·Due to adopt advanced switching BEC technology, the switching frequency of the on-board BEC may make
some disturbance to receiver when use with some of 35Mhz transmitters and receivers, (such as Multiplex
35Mhz transmitter and receiver). We strongly recommend to disconnect the red wire from the ESC’s receiver
lead and use a separate receiver battery to power the receiver and servos when use with some of 35Mhz transmitter and receiver.
·The controller will automatically power off the motor if the battery voltage drops below the programmed
cut-off voltage (factory preset at 6.0V). Try using a smaller prop on the motor, or using batteries with a higher
rating. It is especially important for the user of Li-poly cells.
·Allowing water, lubricants, moisture or other foreign objects inside the ESC will VOID the WARRANTY.
Exposure to CA glue or its fumes can cause damage and malfunctions; this will also VOID the WARRANTY.

Ⅵ Using the ESC
·Calibrate the throttle range of transmitter at the first time to use the controller (Recommend)
- Correctly connect the ESC with brushless motor, plug the receiver lead of ESC into receiver ( usually into
Channel 3);
- Put the throttle to the highest position, turn on the transmitter;
- Power on the receiver, ESC and motor. There are 3 beeps emitted from the motor, which indicates all electronics are correctly power on for the setting.
- Then there are 4 long beeps emitted from the motor ♪ ♪ ♪ ♪ .
- During or after the 4 long beeps , move the throttle to the lowest position, at this point, you have calibrated
the throttle range of your transmitter;
- Waiting one second, there will be two beeps emitted from the motor ♪
NOTE: 1). If you have succeeded in calibrating the throttle range of transmitter, the throttle range will be displayed in ‘Programming Set’ window when you connect the controller to PC. The factory preset throttle
range is 640 uS.
- Calibration of throttle is completed.
·Program the ESC’ s settings or use the default setting (by Eurgle Program Card/ on PC/ by throttle

Eurgle ESC s offer eight user programmable features, including low cutoff voltage, current limiting, brake type,
timing advance, cutoff type, soft start, governor mode and PWM switching rate. Through the USB Linker, Eurgle
ESC-80A can be programmed easily on PC, and it is also good compatible with Eurgle Program Card or program
via throttle stick of the transmitter.

NOTE: Low Cut-off Voltage can protect the main battery from being discharged too low, and provide the normal
operating voltage to receiver and servos.
· Current Limiting
Option 1: Very Sensitivity
Option 2:Standard(default)
Low over-current threshold, will rapidly shut-down.
Moderate over-current threshold, will shut down after a slight delay.
Recommended for inrunner motors.
High over-current threshold, will shut down after a slight delay. Rec-
Option 3:Insensitivity
Option 4: disabled
ommended for outrunner motors. Only experienced modelers
should use this programming feature
Current limiting detection disabled. Only experienced modelers
should use this programming feature.
NOTE: Default setting is recommended. If you change the setting, damage to the controller as a result of over
current will be not covered by the manufacturer’s warranty.
· Brake Type
Option 1:Brake disabled
Brake disabled is mainly used for helicopters.
Option 2:Soft brake
Option 3:Hard brake
Soft brake provides 50% of full braking power. General aircraft use, with fixed or
folding prop
Hard brake is 70% braking power. Direct drive applications where more braking
power is required. Hard brake should only be used below 12V.
· Timing Advance
Option 1: Low advance timing
Option 2: middle advance timing
Recommended for most motors .Gives a good balance of power and efficiency.
5 °~ 20 °
Option 3: High advance timing
Recommended for most of higher pole count motors
15° ~ 30 °
Recommended for most of all brushless motors.
· Cutoff Type
When battery voltage reaches cut-off voltage the motor will shutdown immediOption 1 :Hard cutoff (default)
ately. Motor can be restarted by closing the throttle to the lowest position and
then move the throttle as normal
When battery voltage reaches cut-off voltage, the ESC will slowly reduce motor
Option 2: Soft cutoff
power to zero, you will notice a decrease in power and it is time to land, the throttle maintains its full linear response.
NOTE: Soft cutoff is always automatically active in Governor Mode.
·Start Type
Option 1: soft start
Recommended for helicopters
Option 2:standardstart (default)
Recommended for most of the fixed or folding prop airplanes, and some helicopters.
Option 3: Fast start
Recommended for fastest startup.
· Governor Mode
Option 1: Auto calibrating throttle
Recommended for general aircraft
Option 2: Governor Low
For helicopter application. Controlling frequency becomes slow, control gain becomes increasing.
Option 3: Governor High
For helicopter application. Controlling frequency becomes faster, control gain becomes decreasing.
1. In helicopter application, setting in ‘Governor Low’ or ‘Governor High’ is required. And we recommend to set the start type in ‘Soft start’ to get much smooth start for your helicopters.
2. In ‘Governor Mode’, the start time is generally between 10~45 seconds, which is different depend on
the load.
3. In Governor Mode, the brake is always disabled and soft cutoff is automatically active.
· PWM Switching Rate
Option 1:8KHz(default)
Recommended for most brushless motors
Option 2: 12KHz
Recommended for low inductance motors
Option 3: 16KHz
Recommended for very low inductance motors
Note: we strongly recommend only the experienced modeler could change this setting.
