5 deg/s?

That is the most worthless post!  Why don't you try and list actual specs for the sensor.

Lame post how about a little info, product name part number???

Picture is linked.

@ Joe, because, other than the fact that it is new and 3 axis and has 5 deg/s drift, I don't know anything useful. It will have to be tested etc...

Yes, that's a bit confusing, but the picture is indeed linked. Normally on DIY Drones, clicking on the picture just brings up a larger picture, so I can understand why people would expect the same here. A tip for next time..

Datasheet is bare bones
Comment by bGatti on April 2, 2011 at 6:27pm

Most importantly, the Data Sheet doesn't specify the internal vibration frequency - which is the first clue to where the harmonic-induced-error characteristics might compare to others. (perhaps it's important to note here, that the cost and performance of Gyro's is the single largest factor in the cost and performance of an IMU-flight controller - I'm pretty sure its important to know when a new gyro drops - and for those skilled in the art, a part number is equivalent to a hyper-link.)

 

Think of a new part (post) like a seed - you never know what will grow. (water nicely).

5deg/s is zero rate output over temperature which is not that bad but noise density  of 0.12 deg/s/√Hz is two and half times bigger than ADXRS610 (0.05). The mechanical resonance is 10Khz.
