FWIW, I've been pretty satisfied with the Hardware kit I bought from Wicks Aircraft back in 2011. I've only found it to be missing the following things:
- Heyco .75" snap bushings for the aft fuselage rudder cable holes
- Heyco snap-plug for the tailwheel area
- Incorrect size sheet metal screws for inspection hole covers
I'm sure I'll find one or two more by the time I'm done (though I've completed the wings and tail at this point). Wicks' website is not the easiest to use, so for missing parts I've usually gone and ordered replacements from Aircraft Spruce.
Additionally, I've found that Sonex did not supply some CCC-46 rivets that are specified on SNX-F25 (side aft fuselage assembly) for riveting the rudder stop plates and lower longerons to the fuselage skins. And in one or two places I think they specified a slightly incorrect bolt length. Often you can just add a washer or two (see AC43-13 or
Ron Wanttaja's excellent book on Homebuilding), or substitute a slightly longer bolt; although this may mean running 1 short later in the process. Its a bit frustrating, but its all part of the build process!
Take care,
