I remember the Centuri 13mm kits came with Spec-Plates... Speaking of The Centuri mini kits/motors...I also remember test firing a couple of A4-2M 's (the long Green Casing) and having a pretty good burn through on the side of the motor casings...the Sure-shot "dots" had lost their glue but the pyrogen worked like a charm...was it just me or were those great ignitors?
