The Spektrum RC Firma 40 Amp Brushed Smart 2-in-1 ESC & Receiver was developed with Crawlers and Scale models in mind. The Firma 40 Amp Brushed ESC features a waterproof and dust proof design to keep you going down the trail in nearly any conditions. It has a powerful 3 amp BEC for your lights, winch and steering servo. And it’s fully programmable using an optional programmer box, so you can customize the ESC to suit your model’s needs and your own driving style.

The Firma 40 Amp Brushed ESC also helps reduce clutter and streamline your setup with an industry-leading, integrated 4-channel DSMR®/DSM2® receiver. This integrated receiver system is perfectly suited to allow drivers the options for winch setups, dual steering mixes and more. And setup is simple, with a convenient bind button and no complicated calibrations.

Plus, when used with a Spektrum Smart compatible transmitter, you can easily see valuable battery and ESC data easily in real time right on transmitter — including motor current, input voltage, remaining battery capacity and other information that will help endurance RC trailers increase efficiency and extend battery life and run time. When using Smart telemetry, alarms and parameters are setup automatically on your Spektrum transmitter.
