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. Key features include:

• Low voltage cut-off
• Overheat protection
• 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:

• CNC-machined aluminum heatsink can for improved durability and heat dissipation
• Precision-balanced rotor for stable operation
• High-purity copper windings for maximum energy conversion and efficiency
• Oversized ABEC5 bearings to support high-speed performance with reduced wear

With a 50,000 maximum RPM rating, this motor is engineered for reliability and top-tier performance.

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 such as:

• Low-voltage cut-off
• Brake and reverse force
• Throttle response range

This makes it a valuable tool for dialing in your setup to match track conditions, battery preferences, or driving style.
