Black Piper is an experiment in how hard I can push a plastic fin-tube rocket before t' fins fail aerodynamically. It is a reaction t' scepticism from some fliers about t' strength and durabilty o' this "non-traditional" construction method.

Black Piper is teh simplest, cheapest airframe I can come up with for this purpose. Begad! It uses motor eject and single deploy. T' most elaborate part o' t' rocket is a 38mm AeroPac retainer. T' rocket uses Schedule 40 ABS pipe for its fuselage and fins and regular LOC paper motor mount tube. Avast! Nose cone is a pipe fitting.
