[PSUBS-MAILIST] gyroscope compass

[Jim Todd via Personal_Submersibles]

Hank,
They're not all that big. Almost every airplane I've ever flown had one. The only ones that did not didn't have a starter either. Go to a small local airport and someone will hand you one to look at.  Or you could just get a 1" solid state accelerometer to feed into a display. There are some discussions of all the above in old threads. I'll send a link or two when I'm home again. 
Cheers,
Jim T.
