STEP 5: SPEED CONTROL SET-UP
Before you begin this step, the ESC should be connected to the throttle channel
on the Rx, the Tx should already be adjusted, and the ESC switch should be in
the off position (refer to Step 3 for Tx adjustment).
1) Connect the battery pack to the ESC, turn on the Tx, then the ESC.
2) NEUTRAL POINT: Leave the throttle trigger in the neutral position. Press and
hold the ESC’s pushbutton until the green LED begins to flash, then release
the button.
3) FULL THROTTLE: Move the throttle trigger to full throttle and hold until the
red LED illuminates (motor will not operate in set up mode).
4) FULL REVERSE: Move the throttle trigger to full brake/reverse and hold
until both the red and green LEDs illuminate.
5) ABS BRAKES: Return the throttle trigger to neutral. The green LED will flash
briefly, followed by both the red and green LEDs oscillating after about 3
seconds.
a. To activate ABS brakes: Move the throttle trigger to either full throttle or
full reverse (while LEDs are oscillating), then return to neutral. The red
LED will flash to confirm ABS brakes are active.
b. To de-activate ABS brakes: Do NOT move the throttle trigger (leave in
neutral position) when the LEDs oscillate in this step.
6) The ESC is now set for operation, confirmed by the green LED remaining
on.
7) If the motor operates in reverse when applying forward throttle, the throttle
reversing switch on the Tx must be moved to the opposite position.
The acceleration, or traction control function provides 3 optional time delays
which control how quickly full forward speed is delivered to the motor after full
deflection is given to the throttle trigger. This allows the ESC to be customized
to personal preferences or certain track and model conditions.
To set the acceleration / traction control:
1) With the Tx throttle in the neutral position, press and hold the ESC’s
pushbutton for 3 seconds. The green LED will flash, followed by a flashing
red LED.
2) Release the pushbutton, and choose from one of three acceleration time
delays as follows:
a. After one second the red LED will blink ONCE. Press and release the
pushbutton at this time to set a delay of 0.0 seconds. This is often the
desirable delay for normal race tracks.
b. After two seconds the red LED will blink TWICE. Press and release the
pushbutton at this time to set a delay of 0.1 seconds.
c. After three seconds the red LED will blink THREE times. Press and
release the pushbutton at this time to set a time delay of 0.2 seconds.
This is often the desirable delay for slick tracks.
STEP 6: ACCELERATION/TRACTION CONTROL
THERMAL CUTOFF PROTECTION
This ESC has built-in circuitry to sense an excessive heating condition caused
by current overload. If the operating temperature exceeds 100° Celsius (212°
F),
the unit will automatically shut down, as indicated by flashing red and green
LEDs. This is to protect all on-board components and prevent permanent
damage from occurring. The ESC can again be used once the internal
temperature returns to an acceptable level, as indicated by a change in the
setup LEDs.
ESC DOES NOT WORK
Problem: Motor and/or steering servo are dead.
1) Recharge dead batteries.
2) Check for faulty power connections.
3) Check for a damaged connection between ESC and Rx.
4) Reverse polarity at battery. Allow ESC to rest at least 1 minute to reset the circuit
protection system.
5) Internal damage. Unit may require service. See “Service Procedures.”
Problem: No reverse.
1) Tx adjusted incorrectly. Repeat Step 5 above.
2) Reverse transistors might be damaged, and unit may require service. See “Service
Procedures.”
Problem: Case is melted.
Internal damage and unit requires service. See “Service
Procedures.”
Problem: ESC runs with switch off.
Drive transistor may be blown and unit may require service. See “Service Procedures.”
ESC WORKS BUT OTHER PROBLEMS EXIST
Problem: Rx glitches or stutters during acceleration.
1) The three required motor capacitors are not installed or have broken.Re-check all
capacitors.
2) The Rx signal is intermittent due to a large voltage drop during acceleration. Use an
external battery and a non-BEC
Rx designed to be used with ESCs. Pay special attention
to remove the red lead from the Rx to ESC harness prior to powering up the ESC or Rx.
3) Rx mounted too close to ESC causing interference. Relocate Rx away from ESC.
4) Check for faulty power connections.
5) Use of an AM radio system might be resulting in erratic signals. Use of an FM radio system
might be necessary.
Problem: Model runs slowly or has no acceleration.
1) The ESC is not set up properly. Repeat Step 5 above.
2) Check for faulty battery and/or motor connections.
3) Tx is improperly adjusted. Repeat Step 3 above.
Problem: Steering servo works but motor is dead.
1) Motor brushes are hanging up, worn out, or motor is bad. Clean or replace brushes and
check motor.
2) Check for faulty motor connections.
Problem: Overheated motor or hot power plugs.
1) Motor is geared too high. Change to a lower gear setup.
2) Binding in the vehicle’s drivetrain. Check to make sure nothing is interfering with the
models’ drivetrain.
3) The motor is shorted electrically. Check the motor for shorts and replace if necessary.
4) Check for faulty motor connections.
Problem: Motor runs backwards while forward LEDs are on.
1) Motor is wired backwards. Re-check Step 5 above.
2) A “reverse rotation” motor is being used. Replace with a forward rotation motor.
Problem: Motor runs backwards when forward command is given, even though LEDs
match the motor direction.
Move the Tx throttle reversing switch to the opposite position.
Problem: Model runs properly, then motor goes dead.
The built-in thermal protection may be automatically shutting down power to the ESC due
to overheating conditions. Check for binding drivetrain, bad motor or incorrect gear ratio for
track conditions. Adjust gear mesh, replace motor or change gear ratio. The ESC should reset
in a few minutes and operation can again be attempted.
TROUBLESHOOTING GUIDE
A time delay can be set for changing the direction of motor travel from forward
to reverse. This delay helps to prevent damage to gear assemblies that can
result from slamming the motor from high speed forward movement directly to
reverse. The reverse direction control for this ESC can also be completely
disabled or “locked-out.” Many races require ESCs be used which do not have
reverse function.
Follow these steps to set reverse delay or reverse lockout:
1) With the Tx throttle in the neutral position, press and hold the ESC’s
pushbutton for 5 seconds. The green and red LEDs will flash.
2) Release the pushbutton, and choose from one of two reverse time delays or
reverse lockout as follows:
a. After one second the green and red LED will blink ONCE. Press and
release the pushbutton at this time to set a delay of 0.3 seconds. This is
often the desirable delay for normal race tracks.
b. After two seconds, the green and red LED will blink TWICE. Press and
release the pushbutton at this time to set a delay of 0.8 seconds.
c. After three seconds the green and red LED will blink THREE times. Press
and release the pushbutton at this time to completely lockout or shut
off reverse.
STEP 7: REVERSE DELAY & REVERSE LOCKOUT SETTINGS
Note: ESCs that operate normally when received will be charged a minimum
service fee and return shipping charges. Before sending your ESC in for service,
it is important that you review the Troubleshooting Guide in this instruction
sheet. The ESC may appear to have failed when other problems exist in the
system, such as a defective Tx, Rx or servo, or incorrect
adjustments/installation.
• Hobby dealers are not authorized to replace ESCs thought to be defective.
• Do not cut the input harness, switch harness, or power wires of the ESC
before sending it for service. A fee will be charged for cut wires which must
be replaced for testing.
