brakes before the engagement of reverse, and the Roosters feature Novak’s Smart Braking CircuitryTM that brings the model to a slow speed before hitting reverse to save your vehicle’s gearbox and reduce speed control heating.

These speed controls feature the original One-T ouch Set-Up

(There’s nothing easier!), exclusive Polar Drive T echnology

for the smoothest throttle response and improved radio system performance, and Reverse Disable that locks-out reverse for racing or forward only use.

Other features include built-in brake light circuitry to power two high-intensity LEDs for enhanced realism (available separately in the Novak Brake Light LED Kit #5655), Radio Priority Circuitry control even after the battery has discharged, and dual- level thermal protection.

STEP 1

CHANGING THE INPUT HARNESS

The Rooster speed controls come with the industry standard input

harness connector. This connector works major radio brands. However, with some older style receivers the sequence of the wires in the plastic connector housing needs to be changed. This is an important step,

because the electronics inside the receiver may be damaged if the wiring sequence is incorrect. Changing the wiring is

easily accomplished as described below.

JR • Hitec • New KO • Airtronics Z

If your receiver is a JR, Hitec, Futaba, new KO, or an Airtronics Z (blue case) you do not need to change the sequence of have tabs on the input harness openings as in Figure 1.

• Insert the input plug into the receiver with the BLACK

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 (See Figure 2).

• Interchange the red and black wires in the plug plastic

of the ESC's input harness as shown in Figure 3 below.

• Insert the input plug into the receiver with the RED wire

toward the outside edge of the receiver case.

MOUNTING INSTRUCTIONS

1. INSTALL SPEED CONTROL

The two Rooster speed controls should be positioned back to back and mounted on their sides in the rear electronics area of the E-Maxx as shown in the E-MAXX Installation sided chassis.

Note: Heat sinks are required with Rooster ESCs for optimum performance and power handling. The Rooster heat sinks come factory installed and must not be removed.

DO NOT SHORT CIRCUIT HEAT SINKS The three banks of

transistor tabs are separated by plastic on the case top. Each bank of heat sinks should never contact each other or other conductive objects (metal, etc.), damage the speed control.

Replacement Rooster heat sinks available in Novak kit #5409.

2. INSTALL ON/OFF SWITCHES

Determine a convenient place to mount the switches where they will be easy to get to. Mount the switches using double-sided tape or with screws through the hole in the base of the switch housings.

In our install, we mounted the switches to the E-Maxx’s stock switch holes with the screws that held in the E-Maxx switch. In this location, just ahead of the left rear tire, the switches are easy to get to without removing the body.

3. RECEIVER NOTES

If you are not using the stock E-Maxx receiver, be sure to 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. Mount the antenna close to the receiver and trail any excess wire off the top of the antenna.

HOOK-UP INSTRUCTIONS

Refer to Quick Set-Up Installation & Connection Photos on front

1. INSTALL MOTOR CAPACITORS

Electric motors generate radio noise that can interfere with your receiver and cause radio problems. Included in the ESC accessory kit are six 0.1µF (50V) nonpolarized, ceramic capacitors. Three capacitors must be installed on each motor to help reduce the noise generated by the motor and to prevent ESC damage.

Solder 0.1µF (50V) capacitors between:

• POSITIVE (+) motor tab & NEGATIVE (

• POSITIVE (+) motor tab & GROUND tab*.

• NEGATIVE (

*If your motor does not have a ground tab, solder the capacitor leads to the can of the motor as shown below.

-) motor tab & GROUND tab*.

Extra 0.1µF capacitors are available in Novak kit #5620

2. IMPORTANT NOTE ABOUT SCHOTTKY DIODES

NO SCHOTTKY DIODES

Schottky diodes must NOT be used with reversible speed controls. Using a Schottky diode will damage the speed control and will void the warranty.

3. CONNECT SPEED CONTROLS TO THE Y-HARNESS

After the proper wiring sequence has been configured to match the receiver (Refer to Step 1), plug the input signal harnesses from both speed double end of the included

The brown wire on the Y-Harness is the negative (-) wire and should connect to the black wire of the ESC.

4. CONNECT Y-HARNESS TO THE RECEIVER

Plug the single end of the

THROTTLE CHANNEL of the receiver.

CONNECT SPEED CONTROLS TO THE BA TTERY P ACKS

Plug the JST/Tamiya connector from the first ESC into one of the battery packs Plug the second ESC into the other battery pack.

*Removal of JST/Tamiya connector voids warranty.

5. CONNECT SPEED CONTROLS TO THE MOTORS

Plug the bullet connector on the YELLOW wire of the first speed control to positive of the first motor. Plug the bullet connector on the BLUE wire of the first speed control

to negative of the first motor.

Plug the bullet connector on the YELLOW wire of the

speed control to positive of the second motor.

second Plug the bullet connector on the BLUE wire of the second speed control to negative of the second motor.

Again, we found that connecting the left side ESC to the right side motor & battery in the truck works best.

TIP: Twist BLUE & YELLOW motor wires once or twice as they go to

the motor to reduce any radio noise emitted from power wires.

MOTOR SELECTION: mum performance. Typical motors are not tuned to operate in reverse, and draw excessive current that can cause ESC overheating. Modified motors timed to 0 (closed end like E-Maxx stock motor) motors are recommended. Ask a hobby dealer to help select a properly timed motor.

Use neutrally timed (0°) motors for opti-
