PSS AOA sensor position standardization

All:

I'm getting close to installing a Proprietary Software Systems AOA sensor in my
wing.
After talking with those folks, there's apparently a lot of Europa builders 
doing
the same
thing, but going about it in very different ways.  There are a two main issues
here:
    1. Where is the optimal position for the sensor
    2. How does one provide access to it?

PSS's comment is that they have been able to provide precalibrated AOA systems
and
optimal installation directions for RVs with the help and cooperation of the 
builder
community
and the factory.  There appears to be enough users in the Europa community that
a
coordinated development of at least optimal installation instructions is 
feasible.
However, this
would really need the interest and involvement of the factory.

The second issue is seeing several approaches.  The basic problem is that the 
sensor
bridges
the upper and lower skins forward of the spar, and therefore requires an 
additional
access
plate for maintenance.  What is the structurally safest, or aerodynamically 
best,
way of doing
this?

Perhaps those that are in the middle of this could join in another discussion 
thread....
