User manual NOVAK RACER-EX

[. . . ] INTRODUCING THE RACER-EX ESC IMPORTANT PRECAUTIONS (ESC= ELECTRONIC SPEED CONTROL) · Do not operate near water!Never allow water, moisture, or any liquid to touch the ESC. · Never use more than 10 cells in main battery pack. If you are building a kit that has a mechanical speed control, do not use the wiring diagram included with the kit. [. . . ] · NEGATIVE (-) motor tab & GROUND tab*. Negative (-) motor tab FET SERVO CONNECTION The Racer-EX is wired for connecting a FET Servo. This type of servo requires a fourth wire connection. 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. Check throttle channel operation with a servo. · 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 throttle channel operation with a servo. 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. · Not programmed­­Repeat programming. · 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. [. . . ] Mount the ON/OFF switch in a convenient place with a piece of mounting tape or screw. MOUNTING THE RECEIVER To minimize glitching, mount the receiver and antenna away from the ESC, motor, servo, power wires, or any large piece (Refer to photosas a front page) of metal (such on chassis) or graphite. If you must mount the receiver on the chassis, mount it on its side with the crystal & antenna as far above the chassis as possible to reduce the chances of radio interference. Mount the antenna as close to the receiver as possible. [. . . ]
