Need help with this. Pulling my hair out!

[CkGordon]

So I stayed up really late last night and have spent the majority of the day building and tearing down rocket setups trying to get this damn DEMV to the Mun. It's driving me nuts! Nothing I do seems to work. Can somebody please post a picture of what a rocket (still on launchpad) capable of lifting a 14 ton payload to Munar orbit should look like?

[Moach]

have you tried instead of lifting it to the Mun, first lift it into low orbit, then launch a booster stage and rendezvous?

i imagine a rocket capable of hauling a 14-tonne mammoth like that would have a massive load of boosters - do you have the Kyle-Winston pack? it has a range of formidable solid boosters of which the larger ones pack so much punch it makes the Shuttle look like a birthday candle

use the Mainsail engine too! - I just love that engine!

The latest video on my stream at twitch.tv/mr_niceguy_ has me hauling that bad boy all the way to duna. Im on my phone atm so i cant get an exact location on the video. But if you go towards the end when i land and go backwards till the launch you should be able to see it.

Edit: http://www.twitch.tv/mr_niceguy_/b/334475324 video there and the whole ship can be seen at 1:21:33

This rocket allowed me to put the DEMV on Duna several times(one on Ike as well). Top stage(lander) can be separated so that the vehicle can land using parachutes(if possible)

He's throwing 14 tons over the fence, not taking 140 tons on an Joolian epic. You really don't need much, 300 tons or less launch weight and a few dozen parts is plenty. Give me a few minutes and I'll come up with something more on the sort of scale you need.

EDIT:

14 tons to the Mun orbit using 19 parts weighing 140 tons (154 tons total launch weight)

It's exactly what it looks like.

7 3200L fuel tanks with aerospikes on the bottom

Stack decoupler

LV-N

400L tank

200L tank (400L in the pictures but it was over half full at the end)

Stack decoupler (payload attachment point)

EDIT2: Must remember screen resolutions are shrinking vertically, picture replaced with shorter one.

Wow I guess less is more. I think I was overly complicating things building more of a rocket than i actually needed.

I now got my big ass space rv cruising around the Mun by studying these replys and then building a new launch rocket with what I learned. Thank you so much everyone! My Mun base is now 2 landers, 3 kerbals, and a remote controlled DEMV (i wanted it remote controlled so I could use it for rescue missions to go pick up crashed kerbals and then return them to base.

I had no idea aerospike engines worked in space I always just saw the C7 manufacturer and assumed it was a plane part and moved on. It is definitely a useful engine!

THANKS SO MUCH!!

Yeah, it looks like a part from a jet engine but it is a genuine real life rocket engine nozzle design. NASA was planning to use a linear aerospike on a shuttle replacement at one point:

Congrats on the successful mun base.
