Main wing spars complete!

Ok, that was easy, thanks to the quick build :)

I tapped the tiedown blocks for the tiedown rings:

and test-fit the Cleaveland rings, which sat just short of flush:

Another task was to enlarge the hole for the stall warning wires and install a bushing:

And last, I enlarged the larger holes on the aileron bellcrank brackets (the white ones from the picture above) and deburred them.

That's it! Hard work :)

Time lapse:

Total main wing spar time: 1.2h ('cause I'm efficient!)
Total main wing spar rivets: 0 (it's held together by quickbuild magic :D )
