&nbspServos 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.

D951TW 32-Bit, Metal Case, High Torque, Titanium Gear Servo

Hitec’s D-Series servo line sets new standards for advanced, programmable technology. Powered by our 32-bit MCU (Microcontroller Unit) and 12-bit ADC (Analog to Digital Converter) industrial science, these powerhouses dominate the servo arena. Their potent combination of wide voltage capabilities, high resolution, rapid response, and patented Smart Sense technology brings maximum performance to all radio control applications. The members of this particular D-Series group are all designed with our extremely durable titanium gears, and the D941TW, D946TW, and D951TW trio boast full metal cases. When you demand ultimate reliability and unprecedented advanced engineering, look to the power of the D-Series servos!
