One of my two $26 Westach probes broke after maybe 30 hours and the
other seems to be on the way out.

Does anybody have experience with the Alcor probes sold by AirCraft
Spruce for $59? Will they last more than twice as long as the

Westachs?

Note: due to my muffler/exhaust design, the probes are located only

2.5"

from the engine.

EGT as high as 1600F.

Hey Chuck how is it going? If you don't make Copper State I will drive
out and take some pictures if you don't mind. I am going to stop off and
see Ron Davis too. Maybe Paul Yaw if he is there.

Hey Paul.  The Westach probes don't seem to last very long in a street car,
but oddly enough they live well in a race car.  I guess because race cars
don't get many miles.  I have not tried anything else.  My neighbor is
bugging me to go to Copperstate.  I have distanced myself from aircraft,
but I did have a good time last year, and Joanna wants to go.  Is it this
coming weekend?  Will there be many people from the list there?  I would
like to meet some of them.  Could you let me know?  If there is a decent
rotary showing I will probably be there.  It's only an hours drive.

Yes this coming weekend. Tracy is planing to be there as well as Perry Mick with
his ducted fan rotary powered EZ. Maybe Chuck Dunlap with his plane.
Also several members on the newsletter from So Cal.

I am surprised. I got the impression that Joanna did not like it last year.
Looks like it should be cooler this year.
