Re: MEMS

The Navaid uses a macro-size gyro, mounted in a normal gimbal.

The problem with the cheap MEMS gyros I have looked at is poor stability 
of their zero output.  They work well for damping rapid changes in 
attitude (e.g., model helicopters) or for holding a heading reference 
briefly (e.g., during a GPS dropout), but they would drift excessively 
if used for something like a traditional gyroscopic heading indicator.
