Servos are powered by the ESC's output to the receiver. If you're using a higher-strength servo than the ESC can support (usually greater than 20kg), you may experience 'brown-outs' where the radio signal can be interrupted and cause erratic driving. This can be helped by plugging a Glitch Buster into the receiver smoothing the current delivery. However, in some cases, you may need to install an external BEC.

The SA-1258TG Plus servo delivers exceptional torque and minimised backlash, making it ideal for RC plane enthusiasts seeking precise control of flying surfaces. Its "Plus" series features enhance its capabilities with Soft Start for smoother operation and Sanwa SSR compatibility for expanded compatibility.
