With the empennage parts sitting around all organized, I finished up my two additional practice kits - the Lightbox and OP-51 (this is the one that comes with your Empennage kit). Pro-tip: Be sure to pick up another practice kit and don't only rely on OP-51 as your only learning piece. While OP-51 does show a lot of different skills, the toolbox and/or lightbox help too. If you're between the toolbox and lightbox, get the toolbox - not only is it cheaper, but it requires more skills and variety than the lightbox - but hey, the lightbox looks WAY cooler - so just get both.
On to the empennage and counting build hours!
