HPI Flux EMH-3S Waterproof Brushless ESC
Brand: HPI
Part No: HPI-112851

The HPI Flux EMH-3S is a robust, waterproof brushless ESC designed to deliver more power and efficiency than the Flux Reload V2 it replaces. Sealed against dust and water, it takes on snow, mud and rain with confidence, making it a versatile choice for on- and off-road 1/10 scale RC cars, buggies and trucks. With broad adjustability, strong current handling and comprehensive protection features, it is ready for fast bashing, precise racing or controlled crawling.
Offering a constant 80A and up to 540A burst current, the Flux EMH-3S handles bigger motors and higher-capacity battery packs while maintaining smooth throttle response. It is easy to set up via a single-button interface or optional program cards, and its sensorless design keeps the system simple and durable.
