I put mine aft, under the HS, on the side of the fuselage.

Just put ours there on the 8 as well. Routes easily to the ADAHRS.

Thanks for the idea of putting the OAT under the HS. True it will give me enough length of cable to the ADHRS
Dave
P.S. I am installing the Skyview form Dynon, I am excited!

I'm using the Dynon Skyview system, also. The length of the OAT probe wiring is perfect for my location. Just enough length to get back to the HS and up to where I put the ADAHRS shelf. Here's some pictures.

Probe on side of fuselage under HS.

Wire coming down from probe to hole in bulkhead with grommet.

Wire runs along floor of fuselage then heads up the bulkhead to the ADAHRS shelf.

ADAHRS is up high on the fuselage. OAT probe wire is stock length and has just a bit of slack.

Dave,

I put mine on the bottom of my right wing, about 1/2 way out (but adjacent to an inspection panel). I figured out there, none of the engine/exhaust heat could possibly cause it to read high.

I had initially drilled my hole in the wing for the Vans stock pitot tube, then later changed my mind and went with the Dynon pitot tube further out on the wing next to an access plate. I put my OAT in the original pitot tube position to fill the hole.

Several other guys I knew put their OAT probe in the Naca inlet so I did that also. It seemed like the OAT was always a little warmer than it should be. The first Winter we went flying one day with an outside temp of 22 degrees F and the OAT showed 62

We live in MN and it was early January 2010. Now we pay good money to get where it is 62 OAT in January but it wasn't that at 1500 AGL with the airport reporting 22 F. When warmer weather came I moved it out to the bottom of the right wing tip and it is very accurate. Just aft of H Stab should be good also. I have toyed with getting an OAT for my Dynon 10D. Presently my OAT is with the Grand Rapids EIS.
I would probably put the Dynon Probe under the left wing tip. It is easier that way since my airplane RV-6A is flying and putting back in the tail would be more difficult.

On our 7, we put the OAT next to the right gear leg, by the Txp aerial.

All was fine until we put louvres under the cowls and it went crazy !

Moved it to the NACA duct and it is still warm, however it is easy to bias the reading in the D120 using the set up.
