For scale rock crawling where precise throttle is essential, the Hobbywing 30120202 ESC provides smooth, repeatable performance in 1/10 rigs. It is built to give dependable low-speed control for both casual trail rigs and competition crawlers.
This unit features a waterproof enclosure that helps protect the ESC during wet runs and river crossings. With an 80A continuous rating and 400A peak, it handles the bursts and holding torque required for technical climbs.
The ESC works with 2S and 3S LiPo batteries and is suitable for 540 or 550 brushed motors, letting you pick the motor and battery combo that matches your driving style. The selectable BEC output (6V, 7.4V, 8.4V) supplies reliable voltage to servos, rated at 4A sustained and 6A peak.
Set up is user friendly thanks to a separate program port for an LED program box and the built-in SET button for quick tuning. Note that the ESC does not accept LCD G2 or OTA programmers, so advanced programming requires other workarounds.
The Hobbywing 30120202 is a compact, water-resistant ESC that balances current handling and straightforward setup, making it a sensible pick for 1/10 crawler builders who need reliable control.
