I would agree the SmartAss is an excellent piece of kit, and like MikeW, I have it fitted to my Europa, and it works very well.
I am in the fortunate position of aso having anAoA indicator on my Dynon Skyview. @MikeW I was able to use another standard Europa static/pitot probe, suitably sleeved with a tube cut with an appropriate angle over the pitot part, and attached via a metal plate to the inspection panel on the opposite wing to the normal pitot/static probe. This saved me digging another hole in the wing, and I was lucky in that the wing had a conduit down its length that I was able to use for the plumbing. PM me if you want the full MOD details
