Description
Spektrum Firma 60A Brushless Smart ESC and 2100KV Sensored Motor Combo is a complete, waterproof upgrade for 1/10-scale crawlers and scalers. This system pairs a 60A sensored brushless ESC with a 2100KV sensored motor (540L-sized) to deliver precise throttle control and strong low-end torque on rocks and trails. It’s designed to work within the Firma Smart ecosystem, offering real-time telemetry and easy trail programming, and it ships ready to install with no soldering required.
Inside, an advanced sensored control system uses a magnetic encoder and rotor position sensor to map throttle to RPM with precision at any speed or angle. The combo provides intelligent speed and torque control with a closed loop, plus pro-level drag braking that can be tuned up to 200% for steep inclines. Built for rugged conditions, it’s waterproof and features an aluminum heatsink with an optional cooling fan, a configurable 6V/7.4V BEC, and heat-resistant connectors compatible with EC plugs. It also supports one-wire telemetry that sends RPM, voltage, temperature and battery data to a compatible transmitter in real time, and offers multiple programming options including the Smart ESC Programming Box (V2 required), SmartLink USB updating and PC programmer app, and transmitter-based programming via Text Gen Telemetry.
