I did all the calculations for the Hohmann Transfer from this thread, got it all right, used Hyperedit to put myself in Kerbal Orbit, did the proper burns at the proper times, and hit the planet smack dab on the mark. My question is, it took FOREVER to get to the point of hitting the planet. The Duna Phase Angle was 45 degrees, and it took Kerbal nearly 300 days to get there. Is this just how it's supposed to work?
