Servo Hitec D645MW

Product detailed description

Powerful metal gear servo with output shaft mounted in two ball bearings for use in RC models of all types. Mainly suitable for RC aircraft models 2-5 kg, RC cars 1:10/1:8 and similar applications.

Replaces HS-5645MG and HS-5685MH servos.

Hitec D digital servos combine ultra-fast response, precision and high resolution of 4096 steps with the possibility of programming. Thanks to the 32-bit processor and 12-bit ADC converter, they far surpass older servos. In addition, they offer a "Wide Voltage" function that allows you to use battery power in a wide range of nominal voltages from 4.8 to 7.4 V.

The new 32-bit Hitec processor combined with a 12-bit analog-to-digital converter converting the signal from the feedback potentiometer offers the best response achieved among servos for RC models. The universal PC interface DPC-11 (usable for all Hitec programmable servos) allows for maximum tuning of the D-series servos for maximum performance in a wide range of applications.

Hitec "Wide Voltage" technology supports all types of receiver batteries with a nominal voltage of 4.8-7.4 V. This means that the servos can be powered directly from e.g. from a 4 to 6-cell NiMH or NiCd battery, a two-cell Li-Fe, Li-Po or Li-ion battery – of course, it is necessary to remember that the thrust and speed of the servo depend on the amount of supply voltage.

With the USB DPC-11 programmer it is possible to program:

• Factory reset
• Deadline width (in 10 steps)
• Direction of rotation
• Speed ​​of rotation
• Neutral
• Soft start
• Deflection size (up to 180 degrees)
• Turn fail-safe on or off
• Set emergency deflection fail-safe
• Overload protection (power limitation 0-50% in case of overload)
• Output shaft with 25-tooth spline (lever is not compatible with older servos)
