This means you can log multiple practice sessions and races without needing to keep the OTA Bluetooth module connected during operation, allowing you to focus entirely on driving while the ESC silently records crucial performance data in the background.
• Comprehensive Data Recording with Real-Time Monitoring — Recorded data includes throttle input, voltage, current draw, temperature, motor RPM, vehicle speed, and other relevant performance parameters. By connecting to the OTA Programmer or LCD Program Box Pro, you can review stored data logs after each run displayed as curve graphs, and you can also monitor real-time data output to check your vehicle's operational status during tuning sessions.
• Freewheeling Function with Temperature Reduction — The innovative freewheeling function affects deceleration and overall operational efficiency to help reduce ESC operating temperature significantly. Compared to the previous XR10 PRO G2S ESC, the temperature theoretically drops by around 15 degrees during operation, substantially improving overall consistency and reliability. This significant temperature reduction is especially beneficial under higher load applications and extended racing sessions, keeping your ESC cooler and more efficient throughout the day.
• Adjustable RPM Decrease Rate for Enhanced Control — The RPM decrease rate setting offers faster deceleration off throttle when freewheeling is enabled, enhancing your control precision in corners and during braking zones. A higher RPM decrease rate results in faster deceleration when you release the throttle, giving you the responsiveness competitive drivers demand.
• Disc Brake Mode with Linear Brake Control — This innovative close-loop brake control creates a brake output that is far more accurate and linear than traditional systems. It allows the feel of your brakes to remain completely linear at all speeds, completely solving the problem of non-linear braking force that is often caused by traditional braking methods due to vehicle speed influences. The Disc Brake Mode also supports Brake Force Curvature fine-tuning, allowing you to adjust the brake bias feeling precisely to your preferences, whilst the normal Linear and Traditional braking modes remain available if preferred.
• Durable Frameless Fan Design — The frameless fan blades are manufactured from special high-durability materials, significantly increasing their rigidity and longevity. This advanced fan design substantially improves the overall reliability of the ESC, ensuring consistent cooling performance even during intense racing sessions.
• Smart Fan Start-Stop Function — This intelligent cooling system keeps the fan off when the ESC does not require active cooling, then automatically activates the fan only when the ESC's temperature rises and cooling becomes necessary. The smart start-stop function ensures your ESC stays within its operational temperature range whilst reducing power consumption and minimising noise when the fan is not needed. Note that this smart function can be disabled through the parameter settings if you prefer continuous fan operation.
• Dual Parameter Setting Mode for Flexible Tuning — The XR10 PRO G3 offers two distinct tuning modes: a simplified Basic mode with 24 essential parameters and an Advanced mode with comprehensive 44 programmable parameters. This dual-mode approach allows newer drivers to focus on common tuning items whilst still giving experienced racers complete access to every ESC setting for granular performance optimisation.
• Extensive Programmable Parameters Over 44 Settings — The ESC contains more than 44 programmable parameters designed to allow a wide range of tuning to suit any driver's needs and preferences.

The Advanced mode unlocks the full 44-parameter programming suite, including throttle curvature, brake curvature, freewheeling settings, disc brake configuration, drag adjustment, brake frequency, boost timing, turbo timing, and many additional racing-focused parameters. You can program the ESC using either an OTA Programmer (wirelessly via Bluetooth) or an LCD Program Box Pro (wired connection). Programming via the SET button on the ESC itself is not supported.
• Does this combo include waterproofing for wet weather or water crossings? — No, this ESC and motor combo does not carry a waterproofing rating and is not designed for wet weather conditions, water fording, or water-exposed environments. It is optimised specifically for dry track racing, drift competitions, and controlled off-road environments. If you require waterproof electronics, you would need to select a different product line, as waterproofing adds weight and complexity that competitive racers typically avoid.
• What makes the Disc Brake Mode different from traditional braking systems on RC cars? — Traditional RC car ESCs apply braking force in a way that is heavily influenced by vehicle speed, creating non-linear brake feel where the car's braking response changes depending on how fast you're going. The innovative Disc Brake Mode uses a close-loop brake control system that creates brake output that is far more accurate and perfectly linear at all speeds. This means your braking feel remains consistent whether you're decelerating from high speed or making gentle speed adjustments during cornering. The system supports Brake Force Curvature adjustment so you can fine-tune the brake bias to match your driving preference, whilst traditional linear and standard braking modes remain available as alternatives if you prefer them.
• What is the benefit of the data logging feature for competitive racers? — The data logging capability records 19 separate 20-minute sessions totalling 380 minutes of storage, capturing throttle input, voltage, current, temperature, motor RPM, vehicle speed, and other parameters. After each session, you can connect the ESC to the OTA Programmer app or LCD Program Box Pro to review your data displayed as curve graphs, allowing you to analyse your driving technique, identify consistency issues, spot voltage sag problems, monitor temperature patterns, and debug performance issues. This analytical capability is invaluable for serious competitors seeking marginal performance gains and greater consistency lap after lap.
• Does the ESC temperature reduction with freewheeling make a real difference during racing? — Yes, the approximately 15-degree temperature reduction compared to the previous G2S model is substantial and directly translates to improved reliability and consistent performance throughout extended racing sessions. Lower operating temperature means the ESC remains more stable, capacitor lifespan is extended, and you can push harder for longer without thermal throttling or performance degradation. This is especially beneficial during multi-round competition days or endurance events where heat accumulation becomes a limiting factor.
• Can I upgrade the motor end plates if I want to use this for on-road touring cars instead of off-road racing? — Yes, the factory default 8.5T motor comes with small-hole end plates optimised for off-road sand protection, but you can purchase and install alternative end plates with large holes that provide superior heat dissipation for on-road racing applications. This gives you flexibility to adapt the motor to different racing disciplines if your interests evolve.
• What connector options are available, and which should I choose? — The ESC ships with no pre-installed battery or motor connectors, giving you the choice to configure it exactly to your preferences and existing battery system. Connector upgrade options include Deans connectors with 3.5mm or 4mm motor bullets, 4mm or 5mm bullet connectors with matching motor wire gauges. Most UK racers use either Deans or 5mm bullets for competition, but Deans connectors are slightly lighter. Choose based on your battery system and what your local racing community standardises on.
