I am having the same problem getting to Eve! I am using the Interplanetary Travel Calculator to get the right angles etc. It easily works for reaching the outer planets, but not Eve or Moho. I always end up with an outward-expanding orbit, towards Duna. Thinking about it, I'm not sure how this method can work for the inner planets. As soon as your orbit goes out of Kerbin you enter a Kerbin-like orbit around Kerbol. Continuing to fire prograde is just going to expand your orbit out further. Turning around and firing retrograde is inefficient and just ends up bringing you back to Kerbin. What am I doing wrong?!
