This year we will use 2.6in BT80 rocket tubes for all our rockets.  We will also constrain ourselves to 24mm motors of the E and F class.  The egg and altimeter will be in a cargo unit.

We have two design nose cones - elliptical and ogive.  Estes makes inexpensive plastic nose cones in both these designs - PNC-80bb and PNC-80k.

PNC-80bb                               PNC-80k
     

The challenge will be in the streamers and increasing the descent rate.
