INJORA Roverin OR30 Brushless ESC & 2204 Fat Viper Motor TRX4M INJOR30-XT2204-4M

The INJORA Roverin OR30 Brushless ESC/2204 Fat Viper Motor and Transmission Combo is designed to deliver improved power, precision, and low-speed control for 1/18-scale micro crawlers, including the Traxxas TRX-4M. Combining a waterproof, sensorless brushless ESC with the 2204 Fat Viper outrunner motor and a 370 transmission, this system provides a comprehensive brushless upgrade for compact crawling platforms. Wireless connectivity and app-based tuning allow drivers to customize throttle response, drag brake, and other performance parameters to suit their driving style. With support for 2S and 3S LiPo batteries, this versatile combo offers flexible power options for technical trail driving and demanding crawling conditions.

About the Brushless Combo

Outrunner Brushless Performance and Precise Throttle Control

The Roverin OR30 ESC is engineered specifically for outrunner brushless motors, providing smooth startup characteristics, more linear throttle response, and improved low-speed modulation. Its 40A continuous current rating and 100A peak current capacity support responsive power delivery in demanding micro crawler applications. Paired with the 2400KV 2204 Fat Viper motor, the system delivers controllable performance for navigating technical obstacles and uneven terrain.

Wireless Connectivity and Customizable Tuning

Built-in wireless connectivity allows drivers to adjust ESC parameters directly through the INJORA LINK app without requiring a separate programming card or wireless module. Adjustable drag brake and throttle settings make it easier to tailor the vehicle's response to different terrain and driving preferences. The ESC also features a 5A BEC with selectable 5.5V or 7.4V output to support compatible receiver and servo configurations.

Waterproof Construction and Integrated Transmission

Designed for outdoor crawling, the OR30 ESC and Fat Viper motor feature waterproof protection to help handle wet and muddy conditions. The included 370 transmission features an aluminum housing, stainless steel gears, a 24.4:1 gear ratio, and 32% underdrive for controlled crawling performance. Built-in ESC protections against low voltage, overheating, overvoltage, overload, motor stall, and throttle signal loss provide additional safeguards during operation.
