Default does strength of servo increase with every decimal of voltage?

I have the 5065mgs on my trex and s9257 on tail.

the 9257 says 4.8v only why i havnt a clue, but the lowest option i have is 5v anyway on all of the escs i have.

my questions are:

. what would be the best option to get the 5065mgs running at the best i can with that setup?

. Is the 1.8kg @ 4.8v sufficient for my trex 450 pro? im not a massive fan of aerobatics but i like it on occasion, but I'm running flybarless system so faster reaction time is preferable.

. Do many people use the 5065mg for cyclic on flybarless systems, how do they hold up? if not what hitec alternatives are there?

will increasing the voltage to ..... say 5.5v give me 2.0kg or is it a non linear step in power as voltage increases?

thanks in advance guys

The 1.8kg is fine, it's more the speed and refresh rate that matters. Also it should be easy for you to look up the specs for that servo, as long ad you don't exceed the max rated voltage you'll be fine. I run MKS DS92A+ for cyclic

HS-65MG
Operating Speed (4.8V): 0.14sec/60 at no load
Operating Speed (6.0V): 0.11sec/60 at no load

Stall Torque (4.8V): 25 oz/in. (1.8kg.cm)
Stall Torque (6.0V): 31 oz/in. (2.2kg.cm)
As with all servo, the higher the voltage, the higher the speed and current draw = faster burn out.
.

. Hitec 2013 Servo Chart

Futaba S9257 specs.
4.8v is the nominal voltage of a 4 cell NiMH/NiCD pack which can be 5.8v when fully charged,
dropping to and running at about 5.3v for majority of time before sudden fall to below cut off,
so a 5.0v switchmode regulator/UBEC is AOK.
