Hitec D-Series 32-Bit Servos

From Hitec:
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!

Features:

• High Response Circuitry
