The Holmes Hobbies Receiver Bypass Adapter with Auxiliary Output allows the use of an external BEC for servo power without needing to disable your ESC’s internal BEC! This is a must-have adapter for any crawler running over 300 ounce/inch servos! This is the latest model, made with thicker 22 gauge wire to create a lower resistance connection that can deliver more power.
NOTE: Servo connects to +/-/signal plug and BEC connects to +/- plug. Signal/- connector plugs into the servo RX channel. Includes additional +/- plug for powering accessories that do not require a signal such as lights. The servo gets signal from the RX and shares a dual ground path to both RX and external BEC to prevent floating ground issues.
