Servo rating question
I have a question regarding servo ratings. They have two ratings. One is torque rated in in/lb and the other is speed rated in seconds.
Now, given two servos - and I'm just making up some numbers here for reference purposes. Let's say one is rated at 200 in/lb and .10 seconds. The other is rated at 320 in/lb and .19 seconds.
Is the torque rating the maximum output that the servo can move? Is the speed rating the time it takes to do a 60* sweep with NO load? Or is the time rating at maximum rated torque load? With the two above servos which would be faster with a load requiring say 180 in/lb. You'd be close to the maximum of the first, faster servo, but barely over half the rated torque of the stronger, slower servo.
And finally, what would happen if I took my stock Revo and installed a 7.2v battery pack? Would I hurt the receiver? Would the servos move faster? Would they die quicker?
