KO ESC VFS-FR3, speed controller, 120A brushed

The KO ESC VFS-FR3 brings a dedicated electronic control unit into brushed RC drivetrains, pairing a 120A rating with a no-limit brushed specification for demanding model setups. In a chassis build or an electronics refresh, this component sits at the centre of throttle control, linking motor response to the rest of the vehicle's drive system. As a speed controller in the Models & Accessories range, it belongs to the technical side of RC model building rather than to body styling or decoration. The brushed layout makes it relevant for hobby projects built around brushed motor systems, where the controller choice shapes how power is managed during acceleration and running. The supplied conformity information states compliance with 2014/30/EU, 2011/65/EU and 1907/2006, with EN55014-1:2021 and EN55014-2:2021 named in the declaration. Batteries are not included. On the bench, the VFS-FR3 fits naturally into upgrade work, replacement tasks and fresh electronics installations for RC vehicles. It suits builders aged 14 years and up who are selecting drive components by specification and who want a clearly identified brushed controller for workshop-based model projects.
