About this part

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.

It is a good concept but when I tried to use mine the connectors became loose did not work as it was supposed to.

I have used this and am still using this in many of my crawlers it's a great concept and product. I've never once had these come undone for me.

Works great. Easy to use. Hard to go wrong with HH and AMain hobbies. AMain customer service is the best in the business.
