• Three Drive Profiles — Choose between Sport Mode (100% forward, 100% brakes, 100% reverse), Race Mode (100% forward, 100% brakes, no reverse for competition), or the exclusive Training Mode that limits power to 50% forward and 50% reverse while maintaining full braking power, allowing you to match the ESC to your skill level and driving style.
• Patent-Pending Training Mode — This innovative Traxxas exclusive reduces overall power output by 50%, making it dramatically easier for young or new drivers to develop proper control skills and build confidence before progressing to full-power operation, with the ability to change profiles instantly without replacing the ESC.
• EZ-Set Push-Button Programming — Traxxas's exclusive EZ-Set push-button setup combined with a multi-coloured LED indicator makes it incredibly simple to calibrate your ESC and transmitter, adjust programming modes, and switch between drive profiles — no complicated menus or specialist knowledge required.
• Thermal Shutdown Protection — Sophisticated two-stage thermal management automatically reduces power if the ESC begins to overheat from excessive current draw, and completely shuts down the motor if temperatures become critical, protecting the speed controller from damage and ensuring safe operation even during intense driving sessions.
• Traxxas High-Current Connectors — Gold-plated patented Traxxas connectors provide restriction-free current flow with minimal resistance, maximising the power delivered to your motors and ensuring reliable connections that maintain peak performance throughout extended use.
• Microprocessor Controlled — Advanced microprocessor control delivers sophisticated high-frequency operation and low internal resistance, resulting in longer run times, more speed, and more consistent performance across a wider range of driving conditions and battery states.
• Forward and Reverse Capability — Full-function forward and reverse motor control (selectable through programming) gives you complete control of your RC vehicle in both directions with full braking power, essential for competitive racing and recreational driving.

Technical Performance

The EVX-2 is engineered as a brushed motor speed controller specifically designed for 16.8-volt dual-motor setups, making it ideal for high-performance RC models like the Traxxas E-Maxx and other similar vehicles that demand serious power. Operating at sophisticated high-frequency levels with industry-leading low internal resistance, the ESC delivers improved efficiency that translates directly into longer run times and more responsive motor control. The microprocessor-based design provides intelligent power management across the entire throttle range, whilst the gold-plated Traxxas high-current connectors ensure that every amp of available power reaches your motors without voltage drop or connection issues. The completely waterproof construction means the EVX-2 can handle the splashes and soakings that come with serious RC driving, from water crossings on trail courses to muddy bashing sessions in the UK's variable weather. Built-in low voltage detection for LiPo batteries operates in two stages — first limiting power to 50% when voltage nears minimum discharge thresholds, then shutting down completely if voltage falls further — protecting your lithium polymer batteries from the dangerous over-discharge that can cause permanent damage. The thermal shutdown protection system monitors ESC temperature continuously, reducing power if overheating occurs and shutting down if critical temperatures are reached, ensuring reliable operation even during the most demanding driving scenarios. Battery compatibility includes both NiMH and LiPo packs, with the ability to disable low voltage detection for NiMH batteries or activate it for safe LiPo operation. The maximum voltage rating of 16.8 volts (14-cell equivalent) allows dual-battery configurations that dramatically increase power output compared to single-battery setups.

Frequently Asked Questions

• Is the Traxxas EVX-2 suitable for beginners to RC hobbying? — Yes, the EVX-2 is suitable for beginners thanks to the patent-pending Training Mode, which limits power to 50% forward and 50% reverse whilst maintaining full brakes. This makes it far easier for new drivers to develop control skills and build confidence before unlocking full-throttle performance. The EZ-Set push-button programming is also very straightforward, requiring no specialist knowledge. However, the EVX-2 is designed for dual-motor setups, so it's best suited to models like the E-Maxx that require this configuration rather than simpler single-motor RC cars.
• What battery does the Traxxas EVX-2 need? — The EVX-2 is designed for 16.8-volt dual-battery setups, meaning you need two compatible battery packs running in parallel. It supports both LiPo (lithium polymer) and NiMH battery chemistries. The maximum voltage rating is 16.8 volts or 14-cell equivalent. When using LiPo batteries, you must ensure low voltage detection is activated for safety. For NiMH batteries, low voltage detection can be disabled. You will need two fully charged battery packs to achieve the full 16.8-volt performance this ESC is designed for.
• How do I programme the Traxxas EVX-2? — Programming is simple using the EZ-Set button and multi-coloured LED. First, connect a fully charged battery with the transmitter on and throttle at neutral. Press and hold EZ-Set until the LED turns green then red. When it blinks red once, pull the throttle trigger to full throttle and hold. When it blinks red twice, push the throttle to full reverse and hold. When the LED blinks green once, programming is complete. To select drive profiles, press and hold EZ-Set with the ESC off until it shows solid green, solid red, then blinking red (indicating profile numbers). Release when the LED blinks the desired number of times: once for Sport Mode, twice for Race Mode, or three times for Training Mode. Low voltage detection can be toggled on or off by pressing and holding EZ-Set for ten seconds when powered on.
• What is the difference between the three drive profiles available? — Sport Mode (Profile 1) offers 100% forward power, 100% brakes, and 100% reverse, giving maximum performance and versatility. Race Mode (Profile 2) provides 100% forward power, 100% brakes, but disables reverse completely, ideal for competitive racing where reverse isn't needed. Training Mode (Profile 3) limits forward and reverse power to 50% each whilst maintaining full braking power, making it perfect for new or young drivers to safely develop their skills.
• Is the EVX-2 waterproof and suitable for wet conditions? — Yes, the EVX-2 features a completely waterproof design, making it suitable for water crossings, muddy terrain, and wet weather conditions. This waterproof construction significantly extends the lifespan of the ESC and allows you to drive in the variable UK weather without worrying about water ingress damage to the electronics.
• What does low voltage detection do? — Low voltage detection constantly monitors your battery voltage. When voltage approaches the minimum safe discharge level for LiPo batteries, the ESC automatically limits power output to 50% throttle, alerting you that the battery is nearly depleted. If voltage continues to fall below the minimum threshold, the ESC completely shuts down motor output and the LED blinks slowly red. This protection is essential for LiPo batteries, as discharging them too far causes permanent damage. The system automatically resets when a fully charged battery is connected.
• Can I use this ESC with NiMH batteries? — Yes, the EVX-2 supports both LiPo and NiMH battery chemistry. When using NiMH batteries, you must disable low voltage detection for optimal performance, as the voltage discharge curve of NiMH batteries differs significantly from LiPo. The ESC's LED will glow solid red when low voltage detection is disabled. To disable it, press and hold the EZ-Set button for ten seconds when the LED is solid green until it turns red. Never use LiPo batteries with low voltage detection disabled.
