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. Begad! This launch was B6-0 with B6-4 sustainer. Ya scallywag! T' wind picked up from still t' about 10 miles per hour durin' t' launch window, and I launced into t' wind. Apparently too much into t' wind, as t' rocket heaved over and lawn darted.
