This rocket was built from pieces of an Estes Amazon in a starter kit, based around a BT56 tube and with balsa fins scaled down from a Der Red Max template. This launch was B6-0 with B6-4 sustainer. The wind picked up from still to about 10 miles per hour during the launch window, and I launced into the wind. Apparently too much into the wind, as the rocket heaved over and lawn darted.
