DKKY Racing 40A Brushed ESC for 1/16 1/18 1/24 RC Crawlers

The DKKY Racing 40A Brushed ESC is an electronic speed controller built for 1/16, 1/18, and 1/24 scale RC crawlers such as the AX24, FCX24, and FCX18. It accepts 2-3S LiPo or 4-9 NiMH batteries (6-12.4V), delivers 40A continuous output, and works with 030, 050, 130, 180, 380, 370 and similar brushed motors. The unit packs multiple protections—low-voltage, overheat, throttle signal loss, BEC over-current, and short circuit—for reliable, safe operation.

Smoother Control on Tough Terrain

The ESC is designed for smooth, precise throttle modulation, which helps maintain traction on rocks, roots, and steep inclines. This makes it a good match for trail crawling and technical courses where careful throttle application is critical.

Battery and Motor Compatibility

• Battery input: 2-3S LiPo or 4-9 NiMH, 6–12.4V
• Motor support: 030, 050, 130, 180, 380, 370 and similar brushed motors
• Motor speed limits: On 6V or 2S LiPo, keep motor RPM at or below 30,000 @ 7.2V. On 12V or 3S, keep RPM at or below 20,000 @ 7.2V.

Built-in Protections for Safe Operation

The controller automatically shuts down or limits current under these conditions:

• Low battery voltage (protects LiPo from over-discharge)
• Overheating
• Throttle signal loss
• BEC over-current
• Short circuit
