Well, I made it into orbit around Moho, with my mothership having enough fuel to take me home. But I severely underestimated Moho's gravity and didn't have a big enough lander to arrive at the surface then go back into orbit. Oh well, back to the drawing board I guess. All the advice in the topic has been sound so far, I would recommend trying the techniques posted in this thread so far for anyone who is struggling to travel to planets with an inclined orbit, as well as people dealing with how to go to Moho. Thanks
