PMR-TARC14

As I mentioned in my TARC projects intro this rocket is already complete and has flown "successfully".  I am only missing two components for it to meet the competition requirements, an approved altimeter and the foam to protect the eggs.  As far as the technical  work that remains to be done, i need a reasonable estimate of the drag coefficient so that I can start to develop a model to determine how much ballast I will need to add to hit the target altitude.  I am also going to try to see if I can predict the variability of the motor based on some parameter that I can measure out in the field.
Since I am already well over a year behind schedule for this project and am running concurrently with my 2015 project the following table is quite an aggressive flight schedule based on the fact that I will probably have a whining, but cute, 4 year old dividing my attention from every thing that I am trying to accomplish. All in all I am very excited to get this project going again
