alt f12 set orbit help/question

Is there a way to set the ap/pe (to something other then 80km it is by default) of an orbit when launching something using the set orbit and if so how?

Yes. By setting the semimajor-axis and the eccentricity to the appropriate values.

The values in the set-orbit page are the orbital elements of the target orbit, see e.g. the Wikipedia page: https://en.wikipedia.org/wiki/Orbital_elements

One initially confusing issue is that the semimajor-axis on the set-orbit page includes the radius of the target body, in contrast to the altitude,  AP,  PE values given in the game.
