I wish you had started the thread earlier. I would have passed on a couple of tips.
1. The cardstock piece that goes between the outer and inner fin tends to shred / tear on flights or landing. Should be replaced with a piece of balsa during construction. Just my own experience.
2. Don't fly the pretty capsule and escape tower. Easy to get crunched. I 3D printed a "flying" capsule so you can save the pretty one for display.
