Dale;
Aircraft stuff is expensive as the dickens if it's certified airworthy.
Often used stuff can be found in good shape at reasonable prices, though.
Watch out for gauges that use synchros-- these require a synchro sender and
need 115V 400Hz power.
IMHO, the most useful aircraft gauges are the thermocouple EGT, carb air
temp, and airspeed indicators. In fact, my street- legal Manta Mirage didn't
have a speedometer drive after the front suspension was converted to Mustang
II, so I popped a helicopter airspeed indicator in the hole that the VDO
speedometer used to occupy. I mounted a pitot tube in the nose and Voila!, I
was legal. The AZ DOT guys couldn't find anything in the law that sais what
KIND of speedometer was required-- only that one was required.
I bought a nice 250MPH airspeed indicator recently for about $30. I'll use
this in my new car that I'm building. I also have a small 12V to 24V
inverter that will power some interesting a/c stuff.

Keith, as a response to your Tech Questions Post,
I've been looking at Aircraft Spruce and Specialty Co.'s catalogue, labeled
as
Worldwide Distributor of Certified
and Homebuilt Aircraft Supplies. And it does appear to have everything
needed
to build many types of aircraft.
What has really caught my eye are the instrument gauges, specifically,
engine
monitoring of EGT and CHT. I see that some of the
gear is for production aircraft at 24volt and up. Yet, most of the
electronics
that we would use are 12 volt. Question at long last,
Have you guys been using any of this stuff? Besides looking slick, is there
more bang for the buck from Aircraft gear? (as long as comparably priced.)
