Spek
Skill Level 2: Previous Rocket Experience Sug-
gested
The Spek is a two-stage rocket designed specifi-
cally for the National Association of Rocketry's contest
for the "Altimeter Altitude" event. In the single-stage
configuration, it can use a 13mm diameter 1/4A, 1/2A,
or A-size rocket motor. When adding the booster stage,
you can use it in the "B-altitude" event, because two A-
size engines added together is equivalent to the power
of a "B" rocket motor.
The dual-diameter rocket is sized (at the top) for
altimeters that fit into an 18mm payload tube. With its
custom vacuum-formed transition section the Spek
then reduces down to a 13mm motor at the bottom to
decrease the weight and lower the drag. This rocket
also comes with a cardstock fin alignment guide to
assure that the fins are perfectly straight and evenly
spaced around the rocket. This lowers the drag, and
allows the rocket to fly to new record-setting altitudes.
