(I may be the last person on the planet to report this, and you might
be sick of hearing about it already, but I'll take the chance.)

A few months ago there was a certain amount of discussion on various
newsgroups/mailing lists concerning "solid-state" gyroscopes. Well,
today a friend of mine showed me a model helicopter magazine featuring
a (very brief) article on just such a device:

	Nick Papillon, "MacGregor/JR's Solid State Gyro".
	Model Helicopter, August 1993 (issue 38). pp10-12.
	Pub. by Traplet Publications Ltd (England). ISSN 0953-7880

The article actually gives very little information that would be
useful to anyone interested in using it for tracking.  The product
name is the NEJ-1000A and it's made by MacGregor/JR (Japan Remote
Control Co. Ltd).

I'd be interested to know if anyone has any more details on this,
especially whether a "solid state" gyro (it's actually piezoelectric)
would be much less prone to drift than a mechanical one.
