Mun landing with fewest (and only using) LV-909 Engines - Stock w/ MechJeb

[frankgg]

I decided to see if I could do a Mun landing round trip using only LV-909 Engines (the small 50 thrust ones) and it worked!

So I am posting this challenge to see if anyone could use fewer LV-909 Engines - and only LV-909 Engines - Lift off from Kerbal, travel to the Mun, land on the Mun, and make it safely back to Kerbal using only stock parts and MechJeb if needed!

RULES:

- Stock Parts only (With an exception for MechJeb)

- Can only use stock LV-909 Engines (RCS allowed for maneuvering)

- Need to lift off from Kerbal, travel to the Mun, land safety on the Mun, and then make it safely back to Kerbal

SCOREBOARD:

1. 19 Engines - FrankGG

2.

3.

4.

5.

Lets see how badly you guys can kick my butt!

My Craft

I set this craft up so all the engines fire at the start and all the fuel gets transferred from the outside tanks inwards, with 2 tank & engine sections dropping every stage when the fuel is used up. This keeps all the inner tanks full.

Touchdown on the Mun! The two outside tanks used up their remaining fuel right as I touched down.

(If you noticed that little square thing on the side of my lander, I accidentally left the Engineer add-on part on my craft, all it does it tell you your thrust/weight ratio during craft building in the vehicle assembly building and has no effect on the mission flight)

Coming back to Kerbal, I still have 1/3 a tank left!

About to splash down back on Kerbal!

3 engines would be the absolute minimum, as far as I know.

For the mun landing alone i usually just use one LV-909. That\'s enough for a safe return as well.

I updated my post to add detail that this challenge requires you to lift off from Kerbal and travel to the Mun with just LV-909\'s, in case it gave the impression that I was just interested in landed on the Mun from orbit... I\'m talking the whole mission!

But yeah, I probably could have lightened the last stage and just went in with 1 engine and gotten back to Kerbal.

3 engines would be the absolute minimum, as far as I know.

Oh wow, has someone done this? I tried 7 engines at first (1 in the middle, 6 around it) but that only got me to the Mun with no more fuel to land.
