Deadly Re-entry help

[Smidey655]

Since it appears that the deadly re-entry thread was eaten in the great purge, I was wondering if anyone could tell me how one goes about figuring out the angle for the re-entry corridor. I can BARELY manage it with stock parts sometimes, but I want to get much better at it, and also be able to do some re-entries into other celestial bodies with atmospheres. Thanks for the help.

You may wish to consider reducing the multiplier (some have suggested it's more than a bit unrealistic, since on a plausible reenty angle, you can heat hotter than the surface of the sun). I believe you can bring that up with 'Alt+D', and change it, but you'll have to do so each time.
