I guess I was fortunate enough to be ignorant of any sun avoidance requirements; stuck mine in my NACA inlet for fresh air vents, and it seems to read pretty accurately.  I'm wondering how much effect the sun can possibly have on it when there's 200 kt of fresh air blowing on it; would be more concerned with air being heated upstream but other than sticking it aft of the lower cowl outlets / exhaust, can't imagine anything else seriously affecting the freestream temp.  Until, of course, I upgrade to ramjet and start getting real gas effects

At any rate, it seems to work fine in the NACA inlet.

For those of you with an AHARS unit used with a glass panel, where are you locating your OAT probe?  I have a Dynon Skyview and it says do not locate the probe in the sun which rules out the top of the fuselage, in the vicinity of engine heat which rules out the bottom (exhaust) or exposed to cabin heat at the rear of the probe which nixes the clever idea I saw one dude use by mounting the probe in the cabin air NACA inlet.  Now I don't have a clue.  Any input appreciated.
