Thanks soofly! I use colored packaging tape from tape bros and HobbyKing, they appear to be the exact same product. The yellow lines are made from electrical tape, one layer on the lighter strip and 2 on the darker.

Do you have a Lowes near you? That's where I got my spars. jayz was awesome enough to make me 36 spars and mail them to me, though. So I'm set for a few years (months? Haha)
The nnA-10 is getting close.. My goal is to have her released by the end of the year. Thanks for being patient with me on this one, it's definitely the most challenging design I've ever done. Just building a working A-10 is not hard, making the design simple and reproducible for all you guys is what takes some extra attention to do right! Stay tuned.
