New and improved with thicker 22ga wire and lower resistance for more power! This adapter allows the use of an external BEC for dual servo power without needing to disable your ESC´s internal BEC. Servos connect to +/-/signal plugs and BEC connects to +/- plug. Signal/- and signal connectors plug into the servo RX channels. Includes additional signal plug for controlling a second servo. The servos get signals from the RX and share a dual ground path to both RX and external BEC to prevent floating ground issues. A must-have for any crawler running over 300 ounce/inch servos!
