The AOA from AFS was a little finicky to install and in the end it turned out quite well.
I did drill the drain hole a little to aft of the perfect position by 1/8".
Therefore the correct installation positions for the RV-10 from my installation (taking account of the correct drain hole position) is as follows:
-- Wing span location -- Middle of the outboard wing bay. Upper port 9 1/4" and lower port 7 1/4" inboard of the wing skin outer end.
-- Wing chord location -- 9" forward of the wing skin break at the spar
-- Drain hole location -- 7 5/8" forward of the wing skin break at the spar (min was at 7 1/2" to far aft by 1/8") 9 1/4" inboard of the wing skin outer end.
Installed the components with Tank Sealant.
NOTE: Wing Span and Wing cord loacations on the AFS web site, unfortunately no drain hole loation.
