I use a TowerPro sg90.

1.5 ms for the centre position 0 degree, and 2 ms pulse for +90 degree and -90 degree with a 1ms pulse.

But it's definitely not looking like it goes for 90 degree or -90 degree.

I did read, some said "I tested two of them for about 130.000 cycles, without load, at one cyle per second, and 70 degrees travel." .

What does that mean "130.000 cycles at one cycle per second"?

They use "cycle" to mean moved left then right.

They moved it left then right 130,000 times. They did it at a rate of once per second. They moved it 70 degrees, without any load attached.
