Overview
The Spektrum Firma Sensored ESC System is a Combo that includes a Sensored 2100kv Motor and the Firma 60 Amp Sensored ESC, providing a best upgrade for 10th Scale Rock Crawlers and Scalers.
Like every part in the Spektrum™ Smart ecosystem, Firma™ Smart ESCs integrate "plug-and-play" simpleness with the capability to interact with other Smart electronics — together, creating the best-performing RC system for your car imaginable.
Firma Smart ESCs do much more than regulate power. They function like a virtual engineer inside your model, providing a direct path to the vital operating data you need to reach peak performance. Firma Smart ESCs provide you an extra layer of self-confidence that your electronics are all operating at their best.
With Firma Smart ESCs, you'll be better linked to your car than ever in the past — without installing additional elements that all work separately of each other. You will not need additional wires, modules, or links. A Firma electronic speed control offers a one-wire solution for obtaining telemetry data such as RPM, temperature, battery voltage and capacity.
Firma ESCs not only collect the data but also send it to your transmitter in genuine time, rather of only saving it for after-run research study. You're able to adjust settings as required to increase performance on the go. The Firma Smart single-wire telemetry solution has been tested for quality and performance by the best brands in RC. Their decision? Smart innovation is both easier and superior!







ADVANCED SENSORED MOTOR CONTROL

ADVANCED SENSORED MOTOR CONTROL
The Spektrum Firma Smart Spider System features a high-precision magnetic encoder and rotor position sensing unit that offers outstanding 1 to 1 control feel when driving at any speed and at any angle. Completely fit for trail driving, rock crawling competitions and rock racing setups. This improvement in sensored motor control enables the ESC to match your throttle input to the motors RPM with unequaled precision.
 

CONSISTS OF SPEKTRUM FIRMA SENSORED BRUSHLESS MOTOR

INCLUDES SPEKTRUM FIRMA SENSORED BRUSHLESS MOTOR
This combo includes a Spektrum Firma 2100KV 540L sized sensored brushless motor that is handpicked for great performance in a wide range of spider and scaler models. Including a solidified steel 1/8" (3.175mm) shaft and our waterproof sensing unit port adapter, this motor is ready power your car thru whatever you can throw at it.
 





INTELLIGENT SPEED AND TORQUE CONTROL

INTELLIGENT SPEED AND TORQUE CONTROL
The Spektrum Firma Smart Spider System offers a closed loop control, guaranteeing that the esc maintains torque and RPM levels even as driving conditions change. Offering unprecedented control when driving uphill or downhill and even when in wet or loose traction conditions. No matter the terrain, the Spektrum Firma Spider system keeps you in total control.
 

OPTIMUM POWER EFFECTIVENESS SUPPLIES LONGER BATTERY LIFE

MAXIMUM POWER EFFICIENCY PROVIDES LONGER BATTERY LIFE
