Features
This ESC is setup in a simple way for ease of operation. When switch on it, it
automatically searches for the neutral point. When the automatic setup is finished the
motor sends out "Do" "Re" "Me" indicating the neutral point is set and it is ready to
be operated.
The ESC has 2 programmable running modes and a Low voltage protection mode
that can be enabled for LiPo batteries.

Wiring Diagram
Setup
Connect all wires according to the diagram, then switch on the radio (make sure to
centre trims and ensure default settings for a programmable radio)
Switch on the power to the ESC, and you will hear "Do" " Re" "Me", this indicates
that the neutral point is set and the transmission is on. If the motor does not stop
running a short while after the neutral point is set, please switch off the ESC and
switch it back on again to set the neutral point.
Running Mode
To check the current mode
Turn on the ESC and wait for the "Do" "Re" "Me" to indicate the neutral is set and
then look at the status LED
A Flashing LED indicates the ESC is running in Normal mode (Forward, Brake,
Reverse)
A Solid LED indicates the ESC is running in Crawler mode (Forward with Drag Brake,
Reverse)
Changing Running Mode
Changing from Normal mode to Crawler mode
1. Turn on the ESC and wait for the neutral set "Do" "Re" "Me", the LED will be
FLASHING
2. Hold the Program button down and listen for two "beeps"
3. Let go of the button after you hear the second "beep"
The LED will change to SOLID, the ESC is now running in Crawler mode
FTX6557W ESC Instructions
Changing from Crawler mode to Normal mode
1. Turn on the ESC and wait for the neutral set "Do" "Re" "Me", the LED will be
SOLID
2. Hold the Program button down and listen for one "beep"
3. Let go of the button after you hear the "beep"
The LED will change to FLASHING, the ESC is now running in Normal mode
Programmable Protection Option
To check the current status of the protection systems
Switch on the ESC and listen to the motor's "beep"
Motor "Beep--" + "Do" " Re" "Me"
Low Voltage and Thermal Protections are turned OFF and Neutral Point is set
Motor "Beep--Beep--" + "Do" " Re" "Me"
Low Voltage and Thermal Protections are turned ON and Neutral Point is set.
Please note: If you are using a LiPo battery you must turn the Low Voltage
protection on. The Low voltage protection will active if the LiPo battery voltage
drops below 6V, this will cut the power to the motor to protect the LiPo battery
and stop the battery voltage going too low. If you are running NiMh or NiCd cells
you should run with the protection turned off as the voltage protection is not
needed, running NiMh or NiCd cells in the Low voltage mode will not cause harm
the cells but it could cause the ESC to cut out unexpectedly.
If the ESC temperature gets above 90 °C the ESC will shut down to protect the
unit from damage. Once the temperature drops below 90 °C the ESC will begin
operating again.
Changing Protection Function
1. Hold Program button and switch the esc on
2. The ESC will then "beep" to indicate what mode is being set
To turn the protection OFF wait for one "beep" and then let go of the button
To turn the protection ON keep the button held and listen for the second "beep"
and then let go of the button.
3. Once you let go at the selected "beep" the motor will then sound "Do" "Re" "Me"
4. Turn the ESC off and back on and wait for neutral setting "Do" "Re" "Me"
Your ESC is now ready to use in the selected mode
Function
• Forward: Pull the trigger and the car will move forward.
If the car moves a little on its own the adjust the trim (N on the transmitter
picture)
• Brake: Allow the trigger to return to the neutral position and push the trigger
forward.
• Reverse: Push the trigger forward and the car will go into reverse. The car
must be stationary before reverse is engaged. This protects the ESC from
excessive forward/backwards action.
• LED Indicator
Crawler mode. The LED indicator will be solid when the car is not moving, it
will start to flash slowly as the car is moving and when as full speed will be at
a high flash rate. (This works the same forward and backward.)
Normal mode. The LED indicator will be FLASHING when the car is not
moving, it will start to flash slowly as the car is moving and when as full
speed will be at a high flash rate, while braking the LED will be SOLID. (This
works the same forward and backward.)
Warning
Although the ESC is waterproof the rest of the vehicle is not. Do not run the model in
excessive wet conditions or submerge as long term damage and wear can occur.
It is dangerous to touch the motor after running as it emits heat during running and
the cooling plate remains hot after use.
The ESC is compatible with LiPo batteries but you must ensure that the Low voltage
protection mode is turned ON as detailed in the "Changing Protection Function".
