Hello all
I had some sucsess in building ships. I went to Mun, minmus, got back from mun , sent some bases there. Even landed at duna once. What I have problem with is return trip. I started to use drills on my ship and making fuel, but problem were usualy bad choice of engines, or wrong fuel tanks and ofc, bad timing. So I wanted to ask, is there any easier way to set Duna window? Also, I could use ship suggestion for duna return trip. Not to forget I still preffer to use Mechjeb for my burn calculations, but i did not find any way to plan my trip right from start, to minimist fuel cost. I hope this was clear enough lol. Anyway, if you have video link to nice and simple classic rocket for duna return trip, I would apreciate it.
