⚡🏁 Brushless Power Upgrade for ARRMA Grom & Small-Scale RC Platforms
The EcoPower 35A Brushless ESC & 4600kV Motor Combo is a performance-focused upgrade designed for small-scale RC vehicles, including the ARRMA Grom series. Pairing a programmable 35A sensorless ESC with a high-torque 4600kV brushless motor, this system delivers smooth throttle response, strong acceleration, and dependable power in a compact package.
Designed for 1/14, 1/16, and 1/18 scale vehicles, the combo supports 2S-3S LiPo power and comes equipped with an IC2 battery connector.
About the EcoPower Brushless Combo
⚡ 35A Programmable ESC
The included sensorless ESC delivers 35A continuous and 120A burst current with built-in low-voltage cutoff, overheat, signal-loss, and overload protection. Its waterproof and dustproof construction helps provide dependable performance in demanding conditions.
🏎️ 4600kV Brushless Power
The included 4-pole, 12-slot 4600kV motor features a CNC-machined aluminum can, precision-balanced rotor, high-purity copper windings, and ABEC5 bearings. It's designed to provide an efficient combination of torque, acceleration, and top-end performance for small-scale bashers.
🔧 Programmable Performance
The ESC can be tuned using the optional EcoPower ESC Program Card ECP-8021 (sold separately), allowing drivers to adjust settings including low-voltage cutoff, braking, reverse force, and throttle response.
