Bolts
I think I need to clarify my reference to store bolts which I quoted in my last post on this subject.
I actually used AN7-50A and AN4-50A bolts which I bought from an aircraft parts supplier and not your low grade bolts from a local hardware store. These AN bolts were a little tight but they held the wings very well. They also saved any damage happening to the AN1307 and AN1304 close tolerance bolts.
Another comment. If anyone is building an RV-7A check the 8 holes in each WD-721 Landing Gear Bracket for alignment with the holes in the F-704 Centre Section Assembly and that they are also big enough for the close tolerance bolts to pass through them.
The top 4 holes on each WD-721 are relatively easy to check but the bottom 4 holes are much more difficult, especially on a Quickbuild. I have had to modify all 16 holes on my WD-721's to provide clearance to the bolts.
Cheers,
