Brand: Hitec
Part No: 2221019
Backorder: Expected 26th June 2026
Request Stock NotificationThe Hitec D955TW Wide Voltage Ultra Torque servo (2221019) brings advanced control and durability to demanding RC applications. Driven by a 32‑bit MCU and 12‑bit ADC with Smart Sense engineering, it delivers rapid, high‑resolution response with 4096 step precision. A robust titanium gear train, dual ball bearings and a coreless metal‑brush motor ensure smooth, reliable power, while the wide 4.8–8.4V operating range offers flexible setup across many models. Replacing the renowned HS‑7955TH, the D955TW continues Hitec’s mission of progressive, leading‑edge servo technology.
