Efficent Rocket to the Mun?

[Quilt18]

I need help making an efficient rocket to the Mun but my previous rocket designs fail. the cargo im trying to send to the mun are HOME modules.

How heavy is your payload? If it is too heavy to launch, you could launch it into LKO and then send a tug up to dock to it and take it to the Mun.

I'm not familiar with these. Weight and dimensions?

heres a screenshot. if you have improvements please tell me thanks

You should take a pic more close so we can see the desing of your rocket. And display the delta-v window of MechJeb.

What I can tell from your picture is that you don't use the asparagus desing, witch is the more efficient way to put in orbit huge playloads.

I'd suggest trying to be less ambitious for your payload. You'll definitely need to use the asparagus system with the orange tanks to get into orbit, but once you're up there, you can use just one tank of fuel and a few engines (LV-Ns are very fuel efficient) to extend your orbit out to the Mun.

You'll want to use the asparagus system and reduce the amount of fuel you're taking up, because that stuff is heavy.

Unless it's really heavy (50 tons+) you should be starting with much smaller fuel tanks than that. Going straight to the large ones makes your rocket far heavier (and structurally weaker).

You probably don't need the 4 fuel tanks in your upper stage or the Poodle engines attached to them. That extra weight is going to eat up a lot of fuel inside the atmosphere and make it harder to achieve orbit. Once you're in orbit, you really won't need the thrust provided by the 4 extra Poodles. One would probably do the trick.
