Overview

Note

Notice: Brushless electric motors & ESCs have huge amounts of torque at any given RPM. Using too-tall gearing, or a vehicle that is too large/heavy, can result in damage and/or product failure. Please consult your manual and select gearing suitable for the vehicle and terrain, as damage caused by overloading or abuse is unlikely to be covered by the manufacturer's warranty. Always monitor your ESC and motor temperatures closely after modifying your system to ensure they stay within the safe operating limits.

Features

  • Improved waterproof sensored cable interface and upgraded sensored mode for excellent control feel, perfectly matched to EzRun 3652/3665 SD G3 motors.
  • Supports Turbo timing adjustment of up to 32 degrees — in combination with the EzRun 3652/3665 G3, maximum speed is increased by up to 25%.
  • Smart start-stop fan technology: the frameless fan stays off to reduce noise and save power, only activating when temperature rises to a set threshold.
  • Total capacitor capacitance increased by 74% over the previous generation with overheat protection, improving power delivery and preventing capacitor overload.
  • Smart freewheeling technology delivers higher drive efficiency and approximately 25°C lower operating temperatures than the previous generation.
  • OTA Bluetooth module support for real-time data monitoring (throttle, voltage, current, temperature, speed) and data logging via mobile app.
  • IP67 waterproof system for excellent waterproofing and dustproofing across mud, sand, ice, snow, and water.
