I will be home brewing an AOA probe for my GRT system. I have a good handle on the angle to use, but am trying to get creative on the mounting and avoiding 6" of 1/4" tube. I have a Gretz pitot and stalk. I am thinking of attaching a 3/16" tube from the stalk about 1.5" about the pitot itself and pointing forward, possibly forward and angled to the side to avoid turbulence at the stalk. I know that the input needs to be far enough from the wing surface to stay out of the flow around the wing, but don't know how far I have to be.
I am guessing that the standard stalk used on the RVs is far enough away and probably has some margin as well. Does anyone know if a tube 1.5" above the standard pitot location would still be outside the airflow layer on a 10 wing? If it matters, I am not overly concerned with accuracy at cruise speeds, just the mid-range and slow speeds.
Thanks for any guidance you can provide.
