Field-oriented Control

The Spektrum Firma Sensored 2-in-1 System features a high-precision magnetic encoder and rotor position sensor that provides excellent 1 to 1 control feel when driving at any speed and at any angle. Perfectly suited for trail driving, rock crawling competitions and rock racing setups. This advancement in sensored motor control allows the ESC to match your throttle input to the motors RPM with unmatched precision.

Intelligent Speed And Torque Control

The Spektrum Firma Sensored 2-in-1 System provides a closed loop control, ensuring that the esc maintains torque and RPM levels even as driving conditions change. Giving unprecedented control when driving uphill or downhill and even when in wet or loose traction conditions. No matter the terrain, the Spektrum Firma Crawler system keeps you in complete control.

Maximum Power Efficiency Provides Longer Battery Life

When driving with the Spektrum Firma Sensored 2-in-1 System, drivers are better equipped for the long trails ahead. The Spektrum Firma Sensored 2-in-1 System only uses the power it needs to match your desired throttle output, providing substantially more efficient current levels and extremely long battery life when compared with similar sensorless systems.

Pro-Level Drag Brake Adjustment

The Spektrum Firma Sensored 2-in-1 System features a huge range of drag brake adjustability, allowing for drivers to expertly tune their crawlers and scalers depending on their driven train and vehicle weight. Allowing up to 200% drag power, no matter the setup, the Spektrum Firma Sensored 2-in-1 System can keep your vehicle parked at nearly any incline.

Waterproof

The all-weather, waterproof design of Spektrum^™ Firma^™ ESCs allows them to perform in nearly any terrain under almost any conditions. Firma ESCs keep you going through dust, gravel, snow, and water.

High-adjustability Programming Options

Using the Spektrum ESC Programming Box (version V2 required) , you can easily change settings on the trail to suit driving conditions. An easy-to-use Smart Link USB Updating and PC Programmer app is also available.
