STEP 2
TRANSMITTER ADJUSTMENTS
Adjusting your transmitter (Tx) is critical for proper speed control operation. The Tx throttle adjustments are described below:
• ATV, EPA, or ATL - set all to maximum.
• Throttle Trims and Sub Trims - set all at neutral or zero.

OPERATING INSTRUCTIONS
FOLLOW ALL INSTRUCTIONS CAREFULLY!
Features & Specifications
• The ESC 1000 ESC is designed to be used with up to 10A peak motors.
• The ESC 2000 ESC is designed to be used with up to 20A peak motors.
• Motor, battery, and radio connectors are pre-installed.
• High frequency operation provides very smooth control, maximizes battery run time, and reduces operating temperatures.
• Led indicators (non-setup) are red and green (neutral), red for reverse, and green for forward throttle.

STEP 1
MOUNTING THE SPEED CONTROL
IMPORTANT PRECAUTIONS
(ESC=ELECTRONIC SPEED CONTROL)
MOUNTING THE RECEIVER
1. Radio interference can cause the ESC to rapidly switch between forward and brake, overheating the transistors and possibly damaging the ESC. The Receiver (Rx) and its antenna should be mounted as far away from the ESC as possible. Also, try to keep the Rx away from the motor, battery, power wires, servos, or any large piece of metal - such as a metal chassis.
2. Make sure the Rx antenna can be fully extended through an antenna tube and not completely enclosed inside the model. Do NOT cut or coil the Rx antenna.
The following information can help the ESC perform at maximum efficiency and minimize the chance of overheating and radio interference problems.
MOUNTING THE SPEED CONTROL (Figure 1)
1. Locate the ESC in a position to allow for good airflow, with as little obstruction from the model’s outer body or exterior dirt and debris as possible. Maintaining a clean ESC and achieving good airflow across the unit is very important for keeping the ESC cool and maximizing performance.
2. Mount the ESC using double-sided mounting tape.
3. Mount the ON/OFF switch in a convenient place. Ensure that it is securely mounted using mounting tape in a location where it cannot be easily turned off by objects on the track or rough terrain.
• Do not run the car near water! Never allow water, moisture, or any foreign material inside the case of the ESC.
• Never use more than 6 cells (7.2 volts total) in the battery pack.
• Do not attempt to connect the battery pack to the ESC in reverse, as permanent damage to the ESC could result.
• Do not mix instructions. If you are building a vehicle that has a mechanical speed control, do not use the wiring diagram included with the vehicle.
• Never cut or splice the ESC input wires. Do not connect a battery to the receiver’s (Rx) “battery” slot. The Rx receives power through the ESC itself which plugs into the Rx’s throttle channel slot.
• Always disconnect the battery pack from the ESC when not in use.
• Never turn on the ESC before plugging it into the Rx and switching on the transmitter (Tx).
INTRODUCTION TO
ESC 1000/ESC 2000 INSTRUCTIONS
Specifications
The connector included on the ESC directly fits Futaba receivers. By simply clipping off the tab on the side of the connector using wire cutters, it can be directly connected to any Airtronics “Z,” Hitec “S,” or JR receivers. For proper connection refer to your radio’s manual.
STEP 3
RADIO CONNECTOR POLARITIES
Your motor will require three .1µF capacitors soldered as shown. These capacitors will help prevent RF feedback from the motor.
STEP 4
MOTOR PREPARATION
Clip tab
Mount the speed control to obtain maximum airflow over the ESC.

ESC DOES NOT WORK Problem: Motor and/or steering servo do not move.
1) Recharge dead batteries.
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 Step 5 above.
2) Improper setup.
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) The required motor capacitors are not installed or have broken. Re-check all capacitors.
2) Rx mounted too close to ESC causing interference. Relocate Rx away from ESC.
3) Check for faulty power connections.
Problem: Model runs slowly or has no acceleration.
1) The ESC is not set up properly. Repeat Step 5.
2) Check for faulty battery and/or motor connections.
3) Tx is improperly adjusted. Repeat Step 2.
4) Check that the battery is fully charged.
Problem: Steering servo works but motor doesn’t.
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 drive train. Check to make sure nothing is interfering with the models’ drive train.
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.
2) A “reverse rotation” motor is being used. Replace motor 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 slows or stops. Check for binding drive train, bad motor or incorrect gear ratio for track conditions. Adjust gear mesh, replace motor or change gear ratio.

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. You will be programming three positions into the ESC: neutral, full throttle and full reverse.
1. Connect the battery pack to the ESC, turn on the Tx, then the ESC.
2. Press and hold the “set” button until both LEDs are flashing, then release the button.
3. NEUTRAL POINT: Leave the throttle trigger in the neutral position. Press the setup button once; the green LED will flash.
4. FULL THROTTLE: Move the throttle trigger to full throttle and press the button once until the red LED illuminates (motor will not operate in set up mode).
5. FULL REVERSE: Move the throttle trigger to full brake/reverse and press the button once – the red LED will stop flashing. Release the throttle trigger; the ESC is now ready to operate with your system. If the motor operates in reverse when applying forward throttle, the throttle reversing switch on the Tx must be moved to the opposite position.
STEP 5
SPEED CONTROL SET -UP
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.
