MOUNTING ELECTRONICS
1. DETERMINE BEST ESC MOUNTING LOCATION Position ESC away from receiver & antenna as shown in Set-Up photo (on back). Choose a mounting position that will keep the power wires from obstructing movement of the vehicles suspension or the motor pod. 2. INSTALL SPEED CONTROL Use the included double-sided tape to mount the ESC. 3. INSTALL ON/OFF SWITCH Determine a convenient place to mount switch where it will be easy to get to. Mount with double-sided tape. 4. INSTALL RECEIVER Mount the receiver as far from the motor, power wires, battery, and servo as possible. These components all emit radio noise when the throttle is being applied. On graphite or aluminum, place the receiver on edge with the crystal and antenna as far above the chassis as possible. Mount the antenna close to the receiver and trail any excess wire off the top of the antenna.
The XRS Sport Reversible.the perfect upgrade!
Designed with ultra-small surface mount technology & loaded with all the standard Novak features, the XRS is the perfect upgrade. Capable of handling 4-7 cells & motors with as few as 15 turns, the Novak XRS is a great upgrade for your 1/10th scale touring sedan, off-road buggy, or just about any sport application.
The 5V/1A B.E.C. handles most any servo with ease, and Radio Priority Circuitry maintains steering control even after the battery has discharged. Novaks new Smart Braking II Circuitry gives you full range of braking without going into reverse until you shift it into reverse by returning the trigger to neutral.this provides smoother take-offs in reverse and less wear on your drive train. Polar Drive Technology keeps thing cool & improves radio system performance. And of course, Novaks original OneTouch Set-Up means your new ESC is the easiest to program.

STEP 1

CHANGING INPUT HARNESS
The XRS comes with the industry standard input harness connector that works with all major radio brands. However, with some older style receivers, the wiring sequence in the plastic connector needs to be changed at the receiver-end of the harness. This is important because the electronics in the receiver may be damaged if the wiring sequence is incorrect. Changing the sequence is easy to do, as described below.

STEP 3

CONNECTING ELECTRONICS
Refer to Set-Up photo on back
JR Hitec New KO Airtronics Z
JR, Hitec, Futaba, new KO, & Airtronics Z receivers do not need to change the sequence of the ESC's input harness wires. New Airtronics Z receivers have blue plastic cases, & new KO cases have tabs on the input harness openings, as in Figure 1. Insert the input plug into the receiver with the BLACK wire toward the outside edge of the receiver case.
1. IMPORTANT NOTE ABOUT SCHOTTKY DIODES Schottky diodes must NOT be used with reversible ESCs. Schottky use will damage ESC and void the warranty. 2. CONNECT SPEED CONTROL TO THE RECEIVER After the input plug plastic has been properly wired to match the receiver (Refer to Step 1), plug the ESCs input harness into the THROTTLE CHANNEL of the receiver.

Note: The XRS comes with a user-replaceable input harness that has the same connector on both ends. Should the harness come unplugged from the ESC, insert the connector on the end of the harness into the opening under the power wire tabs with the WHITE wire toward the center of the ESC.

NO SCHOTTKY DIODES

PRECAUTIONS
WATER & ELECTRONICS DONT MIX! Do not operate model in or around water. Never allow water, moisture, or other foreign materials to get inside the ESC. 15-TURN MOTOR LIMIT Use only motors with 15 turns or higher. Using motors with fewer turns than 15 will cause overheating and will void the warranty. 4 TO 7 CELLS ONLY Never use fewer than 4, or more than 7 cells (4.8-8.4 volts DC) in the main battery pack. NO REVERSE VOLTAGE! Reverse battery polarity can damage speed controlDisconnect battery immediately. NO SCHOTTKY DIODES Using external Schottky diodes with reversible ESCs will damage ESC & void warranty. DISCONNECT BATTERIES WHEN NOT IN USE Always disconnect battery from ESC when unattended or not in use to avoid possible short circuits. Even if switch is off, MOSFETs may fail & cause shorting of battery pack that could result in fire or burning of ESC & surrounding objects. TURN TRANSMITTER ON FIRST Turn on transmitter before ESC so you will have control of the radio equipment. INSULATE WIRES Always insulate exposed wiring with heat shrink tubing or electrical tape to avoid short circuits.

Old KO (no tabs) no tabs white black red
Old-style KO Old-style Sanwa/Airtronics
If your receiver is an older KO or Sanwa/Airtronics, you must change the sequence of the ESC's input harness wires. Old Sanwa/Airtronics cases are black in color. Old KO cases do not have the tab openings, as in Figure 2 above. Interchange the red & black wires in the plug plastic of the ESC's input harness at the receiver end as shown below. Insert the input plug into the receiver with the RED wire toward the outside edge of the receiver case.

3. CONNECT SPEED CONTROL TO THE BATTERY PACK Plug the WHITE Tamiya-style battery connector from speed control into a 4 to 7 cell battery pack (1.2 volts DC/cell). 4. CONNECT SPEED CONTROL TO THE MOTOR Plug the bullet connector on the YELLOW wire from speed control into the positive connector from the motor. Plug the bullet connector on the BLUE wire from speed control into the negative connector from the motor.

TIP: Twisting the motor wires once or twice as they go to the motor can help reduce any radio noise emitted from the wires.

TROUBLE-SHOOTING GUIDE

Steering Channel Works But Motor Will Not Run
Speed control has thermally shut downAllow ESC to cool downUse milder motor or smaller pinion gear. Check motor connections. Check motor. Make sure ESC is plugged into the throttle channel of receiver. Check throttle channel operation with a servo. Check wiring color sequence of receiver signal harness. Possible internal damageRefer to Service Procedures.
1. Set HIGH ATV or EPA to maximum setting.
[Amount of throw at full throttle]
2. Set LOW ATV, EPA, or ATL to maximum setting.
