Even though I don't have much time for building right now, I'm trying to do an hour or so a day to keep forward momentum. I'm currently working on my left wing spar - drilling #40 pilot holes, then #30, then #11 for the A6's, and #21 for the A5's. It's going well. I could have built both spars at the same time, but I was worried that a mistake made on one would likely get made on the other at the same time. I also wanted to benefit from any insight that I might get as a result of building one - using my new-found knowledge to do better on the second one.
