EcoPower 8020 35A Brushless ESC & 4600kV Motor Combo for ARRMA® Grom

The EcoPower 35A Brushless ESC and Motor Combo is a performance-focused upgrade built for durability and control in small-scale RC vehicles such as the ARRMA® Grom series. Designed for 1/14, 1/16, and 1/18 scale platforms, this combo delivers smooth acceleration, consistent throttle response, and reliable power output. Waterproof and dustproof, it's made to handle all-weather conditions while protecting your electronics with multiple built-in safety features. Whether you're upgrading for speed, control, or durability, this combo delivers balanced power and flexibility.

The 35A Electronic Speed Control (ESC) is built to handle demanding conditions with its weather-resistant construction. This ESC delivers dependable performance with built-in safety features such as low voltage cut-off, overheat protection, and motor overload protection. The ESC is compatible with 2S and 3S LiPo batteries or four-nine cell NiMH packs, while the IC2 connector ensures compatibility and smooth power delivery across a wide range of setups.

The included 4600kV brushless motor features a 4-pole, 12-slot high-torque design that ensures smooth, powerful operation. Built with a CNC-machined aluminum heatsink can, a precision-balanced rotor, and high-purity copper windings, this motor is engineered for maximum energy conversion and efficiency. Additionally, oversized ABEC5 bearings and a 50,000 maximum RPM rating support high-speed performance with reduced wear and increased reliability.

For advanced users looking to fine-tune performance, this combo is compatible with the optional EcoPower ESC Program Card (ECP-8021 - sold separately). This program card allows customization of essential settings like low-voltage cut-off, brake and reverse force, and throttle response range, making it a valuable tool for dialing in your setup to match track conditions, battery preferences, or driving style.
