I have one of those Alpha II kits - notice also that the motor tube is longer than normal...not sure why they changed the internal arrangement, but if you look at the instructions here: http://estesplans.larocketryforum.c...0alpha%20II.pdf you'll see that not only is the motor tube longer but the shock cord mounts to the motor hook (as we often do with Kevlar these days) rather than using the tri-fold paper mount.
