Greetings,
Even as an experienced RV builder, I have to admit that I screwed up the HS-307's. I like to get my mistakes out of the way early
The only reason I mention this is because I still don't see anything in the plans that would stop anyone from making the same mistake. In fact, had I not built a few of these, I wouldn't have realized the mistake until much later.
The problem is drilling for rivets to attach the HS-307's to the rear spar. The plans and manual neglect to tell you not to drill for rivets in the area between the main ribs (center 5" of the rear spar). In this area, you will have 4 bolts drilled with the center bearing brackets, but the rest of the area between the brackets and the main ribs is left without holes to allow for mounting to the fuselage later. If you put rivets here, you'll find them in the way later, and worse than that, the holes may be in a bad location relative to where you need to drill for bolts during the fuselage assembly.
Cheers,
Rusty (can't wait to taper more spar strips...)
