This HobbyStar 80A Brushless Sensorless ESC is a great option for those who want a versatile and rock solid ESC that delivers smooth and reliable power. The perfect match for just about any 1/10 RC vehicle that has a 540/550 brushless motor, and is also a great upgrade for those Redcat Racing RTR 1/10 vehicles that come with a 60A brushless ESC. You can make a lot of adjustments on this ESC by using the optional LED card, including motor timing, initial acceleration, throttle limit, braking percentage, drag brake percentage and more.

The fully enclosed ESC has a built-in fan, is capable of handling up to 4S LiPo battery power and comes prewired with high-quality 12AWG silicone wires. Hook up is super easy; just mount the ESC to the chassis, connect the 4.0mm bullet connectors to the brushless motor plugs and the T-plug to the battery.
