Traxxas #4

Traxxas recommends the High-Output BEC, or battery eliminator circuit, as a required accessory when installing the Traxxas #2255 High-Torque 400 servo in a TRX-4 or TRX-6 model. The Traxxas High-Output BEC is the only battery eliminator circuit designed for a factory-fit in Traxxas models, and ensures maximum performance when adding high power draw accessories to your model.
