[. . . ] Race-ready 0. 0012 350 amps 140 amps 6. 0 Volts/1. 5 Amps PART #1655 PREVENTING RADIO PROBLEMS Radio interference can cause the speed control to rapidly switch between forward and full brakes, causing overheating of the brake transistors and possible damage to the ESC. Here are a few of the most common causes of radio problems: · CAPACITORS NOT INSTALLED ON MOTOR Electric motors generate radio noise that can interfere with the receiver. To prevent radio problems, every motor should have three 0. 1µF (50V) ceramic capacitors installed (see back page). · RECEIVER MOUNTED ON GRAPHITE OR METAL CHASSIS Graphite and metal chassis transmit radio noise generated by the motor. [. . . ] The Novak Input Plug System will convert the ESC's input plug for use with Airtronics, KO, Kyosho, & JR radios. STEP 4 HOOK-UP INSTRUCTIONS 1. INSTALLING MOTOR CAPACITORS Motors generate radio noise that can cause radio problems. Capacitors must be used at all times on every motor to prevent damage to the ESC. Solder the included three 0. 1µF, 50 V, non-polarized, ceramic capacitors between: · POSITIVE (+) motor tab & NEGATIVE (-) motor tab. · NEGATIVE (-) motor tab & GROUND tab*. Negative (-) motor tab FET SERVO CONNECTION The Racer-EX is wired for connecting a FET Servo. The fourth wire from the servo is connected to the small, blue 24-gauge silicone wire coming out of the ESC. In the Racer-EX, this wire supplies 6 volts of power to the servo and is controlled by the speed control's ON/OFF switch. NOTE: Do not allow the blue FET servo wire to come in contact with the chassis or battery terminal, as this may damage the power switch, switch wires and the speed control's PC board, consequently voiding the product warranty. If you experience radio glitching with the installation of the FET servo, try installing a 10µH inductor (usually supplied with servo) in series with the blue wire.

TROUBLE-SHOOTING GUIDE ESC Will Not Program Properly · Too little transmitter throw­­Increase ATV/EPA setting. · Make sure ESC is plugged into the throttle channel of receiver. · ESC SET button not held long enough­­Press and hold SET button until status LED turns solid red. · Make sure metal sockets on Input Harness are locked in place in plastic plug. · Check to be sure transmitter and receiver crystals are a matched set · Possible transmitter, receiver, or crystal problem. Steering Channel Works But Motor Will Not Run [Status LED is solid RED at all throttle positions] · No signal from receiver­­Make sure speed control is plugged into throttle channel of receiver. Check the wiring color sequence & metal socket insertion of receiver harness. Steering Channel Works But Motor Will Not Run [Status LED is RED at neutral / GREEN at full throttle] · Check motor connections. · Thermal Shutdown­­Allow to cool/Check for adequate airflow through heat sinks. · Check wiring and connections­­Check operation of system without speed control. Receiver Glitches/Throttle Stutters During Acceleration · Motor capacitors broken or missing­­Refer to Step 4. · Receiver or antenna too close to speed control, power wires, battery, or motor­­Refer to Step 2. [. . . ] If transmitter settings are changed, it will be necessary to complete the programming sequence once again. If you experience any problems during programming, turn off the speed control and repeat programming. USING A RECEIVER BATTERY PACK The Racer-EX does not require an external receiver battery pack for most racing situations. Built-in Radio Priority CircuitryTM provides complete control of the steering servo even after the main battery pack has "dumped" and can no longer provide the power required to operate the motor. However, applications using multiple high-powered servos, and/or main battery packs with 8 or more cells require the use of an external receiver battery pack to prevent overloading of the ESC's voltage regulator.
