Hitec's tradition of striving to continually advance servo technology has led to the new, hugely desirable, 32-bit D-Series, comprising the D941TW, D946TW and D951TW. Faster and more precise than ever before the programmable D951TW Ultra Torque servo is compatible with voltages ranging from 4.8 to 7.4 and offers a gobsmacking torque of 35.0kg.cm at 7.4 volts. That's not the half of it though, check out the specification then quietly admire the beautifully anodised full metal case and gorgeous build quality. This, then, is a jewel-like, weightlifting, go-faster, water resistant, masterpiece of a servo with the precision and visual appeal of a Swiss timepiece.
