About the Brushless ESC & Motor Combo

Precision-Tuned ESC

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.

High-Efficiency Brushless Motor

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.

Expanded Tuning Options

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.
