Overview

And with Metal Gear would allow user or pilots for higher on Torque and longer life of used.

With speed 0.09~0.07 per sec would give you best speed for your modeler, Other than that Nexus servo will not give you sluggish and vague feeling.

Nexus servos are designed with motors and electrics that operate off the direct voltage of 2 Cell LiPo,LiFe or LiLon receiver battery pack( 6.6V to7.4V nominal Voltage ) to eliminates this would need a regulator for lower chance of power to prevent failure of your helicopter and aircraft.

Also note that the HV servo specs are shown at the higher voltage (7.4V 2S LiPo) but will still operate on a standard 5-cell 6V NiCd, Ni MH battery with a reduction in performance of approximately 10% in speed and torque.
