Spektrum Firma 45 Smart Lite ESC 22S Sprint Brushless ESC - SPMX-1106

The Spektrum Firma 45 Brushless Smart Lite ESC (SPMX-1106) is a 22S Sprint-rated electronic speed controller designed for brushless-powered RC cars where lightweight performance and Smart telemetry are a priority. Sitting within Spektrum's Firma Smart ESC range, the SPMX-1106 delivers 45 amps of continuous current output and is built to work directly with Spektrum Smart-compatible receivers and transmitters, giving you real-time telemetry data such as voltage, current draw, and temperature without needing a separate sensor module. This is a purpose-built RC car ESC aimed at bashers and racers running brushless setups who want integrated Smart technology without the bulk of a full-size controller.

Key Features

• 45A continuous current rating suits a wide range of brushless motor setups in 1/10 and smaller scale RC cars
• Spektrum Smart technology provides live telemetry data including battery voltage, current, and ESC temperature when paired with a compatible Smart receiver
• 22S Sprint specification means it is optimised for sprint-style running rather than extended high-load applications — check your motor and power requirements before fitting
• Lite form factor keeps weight low, making it well suited to lighter chassis builds where mass and size are a consideration
• Compatible with Spektrum's broader Firma brushless system, allowing straightforward pairing with Firma brushless motors for a matched Smart ecosystem
