Firma 130 Amp Brushless Smart ESC (SPMXSE1130)

Firma 130A Brushless Smart ESC is a compact electronic speed controller for brushless RC vehicles that regulates motor output while enabling real-time one-wire telemetry to a compatible Spektrum radio. It is designed to simplify setup and provide telemetry data alongside robust motor control.

Designed for 2S-4S LiPo packs, this waterproof unit features a fast 32-bit ARM M4 processor, an aluminum heat sink, and a cooling fan to keep temperatures in check. A high-current BEC (4A at 6V) powers the receiver and servos, and EC3/EC5 connectors are backward compatible for easy hookup with Spektrum Smart batteries. Multiple programming options are available—button programming, the Smart ESC Programming Box, or the Smart Link USB PC Programmer app—so tuning can be done at the track or from home. When paired with a Spektrum Smart battery, it transmits battery data to the transmitter in real time. The box includes one Firma Smart ESC, a sticker sheet, and a product manual.
