TRX-4M® Brushless Power System Installation Instructions

• Thank you for purchasing the Traxxas TRX-4M® Brushless Power System.
• The 3-channel ECM Brushless electronic control module features low voltage detection for 2s LiPo batteries and EZ-Set® one-button programming to select driving modes.
• The 3350Kv brushless outrunner motor delivers consistent, high-power output, run after run.
• If you have questions or need assistance, call us at 1-888-TRAXXAS*.

Important Precautions

• Your TRX-4M® Brushless Power System is waterproof for use in mud, snow, puddles and other wet conditions.
• Make certain the other components of your model are waterproof or have sufficient water resistance before driving in wet conditions.
• Always disconnect the battery from the electronic control module when the module is not in use or when it is being stored or transported.
• Switch on your transmitter first before powering up the speed control to prevent runaways and erratic performance.
• The motor can become extremely hot during use, so be careful not to touch it until it cools. Supply adequate airflow for cooling.
• Do not change the battery or motor connectors. Improper wiring can cause fire or damage to the ECM Brushless.
• The electronic control module is not protected against reverse polarity voltage.

Batteries and Battery Charging

• The Electronic Control Module (ECM) Brushless requires a LiPo battery with nominal voltage not to exceed 7.4 volts (2s pack). LiPo batteries have a minimum safe discharge voltage threshold that should not be exceeded.
• The ECM Brushless electronic control module is equipped with built-in Low-Voltage Detection (LVD) that alerts the driver when LiPo batteries have reached their minimum voltage (discharge) threshold. It is the driver’s responsibility to stop immediately to prevent the battery pack from being discharged below its safe minimum threshold.
• If you have questions about LiPo battery usage, please consult with your local hobby dealer or contact the battery manufacturer.

WARNING! CAUTION! DANGER

FIRE HAZARD!

This model requires LiPo batteries. Charging and discharging batteries has the potential for fire, explosion, serious injury, and property damage if not performed per the instructions. Before use, read and follow all manufacturer’s instructions, warnings, and precautions. In addition, Lithium Polymer (LiPo) batteries pose a SEVERE risk of fire if not properly handled per the instructions and require special care and handling procedures for long life and safe operation. LiPo batteries are intended only for advanced users that are educated on the risks associated with LiPo battery use. Traxxas does not recommend that anyone under the age of 18 use or handle LiPo battery packs without the supervision of a knowledgeable and responsible adult. Dispose of used batteries according to the instructions.

Transmitter Setup

TQ 2.4GHz Binding Instructions
For proper operation, the transmitter and ECM Brushless must be electronically ‘bound.’ Follow these instructions to bind your TQ transmitter and ECM Brushless. Note: The transmitter and ECM must be within 5 feet of each other.

1. Press and hold the red SET button as you turn on the transmitter. Release the SET button and the “ON” LED on the transmitter will flash red.
2. Press and hold the EZ-set button on the ECM as you plug in the battery. Release the SET button when the LED flashes red.
3. In a few seconds, the LEDs on the transmitter and the ECM will turn solid green indicating that the radio system is bound and ready for use. Confirm that the steering and throttle operate properly before driving your model.

Low-Voltage Detection (LVD)

• The ECM Brushless electronic control module is equipped with three-stage Low Voltage Detection (LVD) that alerts the driver when LiPo batteries have reached their minimum voltage (discharge) threshold.

ECM Brushless Operation

To turn the model on:

1. Turn on the transmitter. Always turn the transmitter on first, before turning on the model. The transmitter’s LED will glow green.
2. Plug the battery into the ECM Brushless. Make sure the battery plug is completely inserted. The LED will glow green.

To turn the model off:

1. Unplug the battery from the ECM Brushless. The battery should always be unplugged from the ECM Brushless when the vehicle is not in use. For this reason, the model is not equipped with a traditional on/off switch.
2. Turn off the transmitter.

Drive Mode Profiles
The ECM Brushless is equipped with three driving profiles.

Sport Mode (Single red flash)

• 100% Forward, 100% Brakes, 100% Reverse.

Trail Mode (Two red flashes)

• Default factory setting. 100% Forward, 100% Brakes, 100% Reverse; Drag Brake at Neutral.

Crawl Mode (Three red flashes)

• 100% Forward, Hill Hold Brakes at Neutral, Immediate Reverse.

To change drive modes:

1. With the ECM Brushless powered on, press and hold the EZ-Set button.
2. The EZ-Set button will flash red once, then twice, then three times.
3. Release the EZ-Set button after the desired number of flashes to select the mode.

Note: If installing the optional two-speed transmission (part #9891), use the Channel 3 port on the ECM Brushless to provide power to the shift servo (part #9892). Swap to a 3- or 4- channel transmitter and you can use the red rocker switch to switch gears remotely. All accessory parts sold separately. Visit Traxxas.com for additional information.
