Just wondering because the sim says my 'D' launches shouldn't have been stable for a little over 4" past the 36" rod that I was using.

Bill,

What length rod did you use on your 'E' flight?

Excuse me if I seem a little slow, but after all this IS rocket science!


Tweener,

RockSim either calculates a value here, or there is a "pre-set" value in the program. I believe I can change that value, but I did not select that value. I've just run the simulations with mostly default values. What I did change was the temperature at launch time, the launch guide length (note, this doesn't necessarily mean a rod), and the Latitude of the launch site.

Craig...
