About this part

The Holmes Hobbies Receiver Bypass Dual Servo Adapter allows the use of an external BEC for dual servo power without needing to disable your ESC's internal BEC. This is a must-have for any dual servo rig 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: 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.

I have this in my Tamiya CR-01 for its 4WS setup, with an old Castle 10amp BEC and Hitec waterproof servos. It works perfect, zero issues. Wires seem high quality, nice and malleable, easy to stuff into a waterproof receiver box. No complaints, does its job.

Using this to power my steering servo and servo winch off of one side of a castle wp bec. Other bec output goes to a high powered light controller. "Two birds stoned at the same time." -Junior
