This rocket was built from pieces o' 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. Aye aye! T' wind picked up from still t' about 10 miles per hour durin' t' launch window, and I launced into t' wind. Avast! Apparently too much into t' wind, as t' rocket heaved over and lawn darted.
