Always use a quality LiPo charger capable of balanced charging and implement proper battery storage and maintenance practices.
• What is the difference between the MAX6 G2 and the previous MAX5 generation? — The MAX6 G2 is an entirely redesigned ESC featuring significantly improved performance. Key upgrades include waterproof sensored operation for all-weather use, intelligent freewheeling technology that reduces heat generation and improves efficiency, support for up to 24 degrees of turbo timing (delivering approximately 20% performance increase), built-in Bluetooth and mobile app integration for wireless programming and data logging, upgraded BEC rated for 25 amps, and completely redesigned internal circuitry for smoother, more linear power delivery. Under heavy load conditions, the MAX6 G2 maintains temperatures comparable to the MAX5, which is impressive given its increased power capacity.
• Does this combo come with a servo or receiver, or do I need to purchase these separately? — This combo includes only the ESC and motor. You will need to supply a complete radio system including transmitter, receiver, and servos for steering and throttle control. If your RC vehicle is a ready-to-run model, it may already have servos and receiver fitted, in which case you only need a compatible transmitter from the same brand (Spektrum, Futaba, etc).
• Can I use this combo with non-Hobbywing motors, or must I use the 4990SD motor? — The combo includes the EzRun 4990SD motor which is ideally matched to the MAX6 G2 ESC. However, the ESC can operate with other compatible brushless motors. Important note: the advanced turbo timing feature and motor overheat protection functions only work with genuine Hobbywing EzRun 4990 or 5690 G2 motors. Using non-Hobbywing motors will prevent these features from activating.
• How do I programme the MAX6 G2 ESC? — The MAX6 G2 features built-in Bluetooth connectivity and is controlled entirely through the HW Link V2 mobile app available for both iOS and Android. Simply download the free app, pair your phone via Bluetooth (effective range approximately 5 metres), and adjust all parameters wirelessly.

• What data can I monitor with the Bluetooth app, and how is this useful? — The HW Link V2 app displays real-time telemetry data including throttle position, battery voltage, motor current draw, ESC temperature, and motor RPM. After each driving session, the app retrieves stored data recorded by the ESC and displays it as detailed graphs showing how these parameters varied throughout your run. This information is invaluable for understanding your vehicle's power consumption, identifying thermal issues, optimising your setup, and diagnosing problems.
• What is the IP67 waterproof rating, and does it mean I can submerse the system underwater? — The IP67 rating means the system is splash-proof, water-proof, and dust-proof under normal usage, allowing operation in mud, sand, snow, rain and wet conditions. However, this does not mean the system is suitable for permanent water immersion or extended soaking. Avoid submerging the ESC or motor in water for long periods, as the protection is not permanent and will degrade over time with use. The waterproofing will also decline due to daily wear and ageing, so care should be taken even with normally wet conditions.
• How hot does the MAX6 G2 ESC get during use, and how is it cooled? — The ESC incorporates intelligent freewheeling technology and optimised power delivery circuitry that reduces heat generation compared to older designs. Active cooling is provided by a 35x35x10mm framed fan that automatically activates when the ESC reaches a preset temperature threshold, then deactivates when temperature drops back to safe levels. This smart fan approach prevents unnecessary noise and power draw during moderate driving whilst ensuring adequate cooling during hard driving sessions.
• Is this the right combo for my Traxxas X-MAXX or ARRMA Kraton 8S? — Yes, absolutely. This combo is specifically listed as compatible with both Traxxas X-MAXX and ARRMA Kraton 8S vehicles. These high-powered 8S monsters demand exactly the kind of performance and reliability that the MAX6 G2 and 4990SD motor combination delivers.
