Firma Crawler 120A Sensored BL Smart ESC

Spektrum Firma Crawler 120 A sensored Smart ESC – for 1/6 crawlers

Built for the big ones: the Firma 120 A is a sensored Smart speed controller for 1/6 crawlers and scalers such as the Axial SCX6 – and for extremely heavy crawlers in general. A magnetic encoder and rotor position sensor give a 1-to-1 throttle feel at any speed and angle, and the closed-loop control maintains torque and RPM even when the surface changes from dry to wet or loose.

The drag brake is pro-level: up to 200 % braking force, so the vehicle stays put on almost any slope, regardless of drivetrain and weight. And because sensored control only uses the current you ask for, the battery lasts noticeably longer than with comparable sensorless systems. Fully waterproof – dust, gravel, snow and water will not stop it.
