The Midge is a two-stage payload altitude rocket
designed specifically for NAR competitions. Use it in
single stage configuration in the A-altitude competition,
or two-stage 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 to carry the NAR
Standard Payload and an altimeter that fit into an
18mm payload tube. With its custom vacuum-formed
transition section the Midge 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 low-
ers the drag, and allows the rocket to fly to new record-
setting altitudes.
