It's $500. Is that a reasonable price?

That's the one I'm thinking of. I can't tell you if the price is right,
only that I think it's a great idea but I still don't have one.

I toyed with the idea of making something like that (turn only, no pitch)
in kit form. The basic idea is really very simple with the solid state
gyros that are available now. About the only complexity is temperature
compensation. I just made the project too complicated by trying to
include a DG-like reference which requires far, far higher precision
than just a TC display.

Yeah, any time you start integrating things get hairy. But if all you
care about is keeping the wings level then maybe all you need is one of
those cheap rate gyros they use in model helicopters and a couple of
LEDs. On the one hand, betting your life on a part made for RC models
seems like a foolish thing to do, but on the other hand, this is just a
backup in case the entire electrical system on a dual-redundant plane
craps out.

Might be worth getting a model gyro just to play around with. Hm, where
did I put that soldering iron?
