ultimately it doesn't matter what the sensor in your gyro is.

you should set it up in normal (non-Heading Hold) mode so that it doesn't drift. you do this by making sure the servo arm is 90 degrees to the incoming rod and then, through a series of test hovers, manually adjust the length of the rod (ie. twist the rod link ends) to lengthen/shorten the rod until it does not drift

Old gyros used to spin up, piezo does it without moving parts.

Give the guy a break mate. He is just asking a question...
So, let's have a short lesson on gyros for you:

the old gyro's that spun up were gimble gyro's and would work by establishing inertia in the spinning ball and measuring angular change.

We use the term gyro, split it into the sensor and processor. The sensor is actually called an accelerometer. Again this measures the change in angle and sens this info to the processor whic then sends up to 333 different servo position requests to the tail servo per second. Normal servos are 50 fps. Accelerometers are made from many things and are engineered in different ways. Cy mini g, Futaba & Spartan have to be the best. I fly all jr gear but they still can't make a good gyro.
