Estes Mercury Atlas Center Of Gravity/Pressure

[bguffer]

Can anyone tell me what the center of gravity or pressure is for a decent flying Estes Mercury Atlas? I've built mine a little heavy in places and plan to use Aerotech E-F motors, and suspect i may need to add a little nose weight.

If there is a rocsim file posted on EMRR, that info should be included--

I didn't see a rocksim file on emrr. I think Sheri's Hot Rockets has a rocksim file for her 24th scale, but i do not believe it is freely available.
