Carl,
Fortunately my important OAT probe only required a button be exposed
to the exterior. Mine is mounted in/on the bottom wing skin just forward
of the middle gear door opening. Why? It must not be exposed to the
sun in normal upright flight, not be influenced by air exhausted from the
engine compartment and it must be away from interior temperature
influence - including heating of the wires near the probe.
I have a secondary probe (5/8" long by 5/16" cylinder exposed) sticking out
from the fuselage flap filet into the space behind the rear wing spar
and forward of the flap hinge line. It is thoroughly insulated from
interior temperature influence and always reads 1C to 3C higher than the
other.
Good Luck,
Grayhawk
