Before you begin this step, the ESC should be connected to the Rx
and batteries, the Tx should already be adjusted, and the ESC switch
should be in the off position. The ESC-15K is an auto-set ESC.
1. Turn on the transmitter and center the throttle trim (minor trim
adjustment may be required once the ESC is set up).
2. Turn on the ESC.
3. Wait 2 seconds (giving no throttle input on the TX) while the ESC
sets itself up, until both the red and green LEDs are lit. You must
do this every time you turn the ESC on.
4. At neutral both the red and green LEDs will be on constantly.
5. Pull the TX’s trigger; the red LED should flash and the truck move
forward. (If the green LED flashes and truck moves in reverse,
adjust the transmitter's throttle reversing switch.)
6. Push the transmitter trigger. The green LED will flash and the truck
will go in reverse.
ESC DOES NOT WORK
Problem: Motors and/or steering servos do not move.
1) Recharge dead battery.
2) Check for faulty power connections.
3) Check for a damaged connection between ESC and Rx.
4) Internal damage. Unit may require service.
See “Service Procedures.”
Problem: No reverse.
1) Tx adjusted incorrectly. Repeat “Transmitter Adjustments.”
2) Improper set-up. Repeat “Speed Control Set-Up.”
3) 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.
Unit will require service. See “Service Procedures.”
ESC WORKS BUT OTHER PROBLEMS EXIST
Problem: Rx glitches or stutters during acceleration.
1) Rx mounted too close to ESC, causing interference. Relocate Rx
away from ESC.
2) Check for faulty power connections.
Problem: Model runs slowly or has no acceleration.
1) The ESC is not set up properly. Repeat “Speed Control Set-Up.”
2) Check for faulty battery and/or motor connections.
3) Tx is improperly adjusted. Repeat “Transmitter Adjustments.”
4) Check that the batteries are fully charged.
Problem: Steering servos work but motors don’t.
1) Motor brushes are hanging up, worn out, or motors are bad.
Replace motors.
2) Check for faulty motor connections.
Problem: Overheated motors or hot power plugs.
1) Motors are geared too high. Change to a lower gear set-up.
2) Binding in the vehicle’s drive train. Check to make sure nothing is
interfering with the models’ drive train.
3) A motor is shorted electrically. Check the motors for shorts and
replace if necessary.
4) Check for faulty motor connections.
Problem: Motors run backwards when forward command is given.
Move the Tx throttle servo reversing switch to the opposite position.
Problem: Model runs properly, then slows or stops.
1) Check for binding drive train, bad motor or incorrect gear ratio for
track conditions. Adjust gear mesh, replace motor or change gear ratio.
2) Check that both batteries are fully charged.
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.
