Continued dimpling all the parts from section 17 through 23 before assembling the AHARS mount (still not sure if I even bother installing it since I don't plan to use it). More than half the time was then spent assembling the left outboard leading edge. MUCH easier than the fuel tanks (no pro-seal and all). No real problems, my riveting practice from the fuel tanks definately transferred over as the outboard leading edge rivets came out real nice. I didn't have to drill out a single one and no smiley faces in the sheet metal. The stall warning vane also installed pretty easy. We'll see how acturate it is bent on the first flight.
