I am fitting my spar box.
I found that rather than use AN5-10A bolts on the lower spar box holes and AN5-7A bolts on the upper ones, I had to use AN5-7A bolts on all of them.
The AN5-10A protruded through the fuselage so far that the nut bottomed out on the bolt shank. The AN5-7A bolts were long enough, but not too long.
I used AN365-524A nuts on these bolts. The latest version of the manual says 5/16 nyloc nuts, but does not say whether to use AN354-524A or AN365-524A. An earlier version specifies AN365-524A.
John E., another builder, advised me to put the forward rudder cables in the guides on the spar box before bolting the spar box in place. This appears to have been good advice because once my rear spar box half was bolted in place, there was no clearance between the guides and the floor to allow the cables to be slipped into the guides.
Next: Wing alignment!
