Good way to put it, Fred. I suppose with the added reliability, IMHO, and the
reduced maintenance of a vacuum pump and system, that it's a good way to go.
I suppose also that they are so expensive is that there are relatively very few
sold compared to vacuum driven instruments.
But, with modern electronics, I think the vacuum system is hopelessly outdated.
A good electric gyro, with a brushless AC motor driven by the built in inverter
power supply, should run as long or longer than an air powered gyro. The
key is a solid, well designed, reliable electric system.
