I took t' airframe from t' take bin at a launch, me bucko, took a nose cone I had lyin' around, rolled a paper cone around it, me hearties, put nose weight. Avast! Made t' engine mount out o' a few layered penny rolls. Used some spare centerin' rings from an alpha kit. Used a fin design scheme from a custom rockets kit. Cut them from a slightly thick sheet o' balsa from a model plain kit. T' upper fins are just cardboard. I rolled t' launch lugs from penny rolls. It resembles a soundin' rocket, arrr, which is why I used t' nike name. Begad! T' SB part just stands for scratch built.
