I ran across a model rocket repair kit that looks like a great thing to take to the field.  It includes:

Shock cord mounts
Tape rings
Safety key
Recovery wadding
12″ (30 cm)assembled parachute
Launch lugs
Shock cords
Launch rod safety cap.

A great addition to anyone’s fild kit. You can get it here:
