Hobbywing have introduced their new Xerun V3.1 1S speed controller. The dedicated 1/12th scale offering is based around the conventional V3.1 but features a BEC system with voltage booster that creates a regulated 6V/3A BEC output for the steering servo from the 1S 3.7V drive battery. This feature does away with the need to use a separate receiver battery pack. Coming in a full CNC-machined aluminium case with built-in on/off switch the controller not only does away with the need for an external receiver battery pack but also sports build-in capacitors for a tidy wiring. The 120A rated speedo is useable with motors down to 3.0T, measures 37.5x31x21.8mm, weights 37.8g and is as highly adjustable as all Xerun V3 controllers.
