I'm trying to figure out aerobreaking with FAR. I've found the aerobreaking calculator at http://alterbaron.github.io/ksp_aerocalc/ but I can't seem to figure out how to calculate the drag coefficient, which I understand is calculated differently in FAR than in vanilla KSP. MechJeb seems to show a 'drag coefficient' value (had to add this from the custom window editor) but the values don't make sense. Most of the stuff I've got has a D.C. of 0.001 - 0.002 and a lander that I've got Jeb returning from Minmus in has 0.000, which really doesn't help me to calculate how to get him safely into a stable orbit. So, can someone tell me how to calculate drag in FAR?
