Launched as a 2-stage rocket, ya bilge rat, usin' t' booster stage from our old Taser Twin. Well, blow me down! Since t' Wizard wasn't designed or built as a 2-stage rocket, I believe thar be a gap betwixt t' sustainer motor and t' engine block inside t' body. Aye aye!  When t' rocket staged, t' sustainer lept across this gap and slammed into t' engine block, causin' t' main stage t' corkscrew at altitude.
