Anyone use 6v systems? does it kill the gyro? Does the battery drain faster?

Does it kill the gyro?

You will have to read the instructions that came with the gyro to see what
the maximum input voltage rating is.

Does it drain the battery faster?

Yes. Most servos have two speed/torque ratings given, one set for 4.8V
operation and one set for 6.0V operation. The faster speed and higher torque
at 6.0V comes at a price, increased current draw.

Some do. Common practice among those that do is to use a regulator in
circuit which drops the power to equal that of a 4 cell (4.8v) pack, thus
resulting in longer run times and also safety incase one cell dies.

If you do into the details and facts though u may decide it's pointless and
can be troublesome, plus the regulator takes some power itself, and switch
mech/tech is modified, I think resulting in a constant, though small current
drain even with the switch OFF.

umm but that's what some do

The regulator that I use does use a small amount of current even with the
switch in the OFF position. There is enough current being drawn to flatten
the battery if left connected thru out the week.
So..normal practice is to disconnect the battery after the end of the flying
day.

If you run the servos at 6V their speed/torque is greater at the expense of increased current drain, and also faster brush wear in the servo motors. Beleive it or not it is possible to wear the brush fingers off a servo motor if you use it a lot !!!

Gryos have built-in regulators in order to operate as the circuits are voltage sensitive so they have their own regulators, so operation at 4.8V and 6V should be possible, but always check the spec sheet for the gyro.The above comment was for a piezeo gyro. A mechanical gyro may not have voltag regulation for the gyro motor so there might be problems, ie gyro motor is going to wear out faster or the gyro's response/sensitivity will change.
