Stratzenblitz75 did a video lag-busting the game recently, and he found that the fuel crossfeed system: the way the game handles many engines using fuel from many tanks at the same time is horribly broken. and this can be worked around for high part count crafts by keeping the engines always only able to see/drain 1-2 tanks at a time. This could be of use if you ever run into a laggy situation? i hope this could help in the future.

You should look up how to do hyper-symmetry. It'd save you a ton of time when trying to place hundreds of engines. Also, when you are 3.5km above the mun? That's the best time to burn prograde to maximize the oberth effect and slingshot much further.

[@oasntet]

@Aaron If you are already planning to use the Mun for a gravity assist, you might as well also burn at Mun periapsis, rather than much later, say at the periapsis of the largest body (the sun). I almost always do this and save hundreds of m/s getting out of the home system (Rhode, in my case).

[@redbaron8670]

One option you could have use (whilst using the method where you copied and pasted the same fuel tank + engines 2:37) would have been to use fuel pipes to drain the bottom tank into the uppers one, and to use all the engines of the rocket. When the bottom tank is empty, jettison it with its set of engines. That way your thrust/weight ratio would have been fine, and the craft would have been simpler

[@ReidCaptain]

Yup, would have been good!

[@SephirothRyu]

@@ReidCaptain People often call this "Asparagus staging" and it is indeed very useful in KSP.

[@jonmab6990]

It would have worked, but the horrible crossfeed mechanics would make the lag horrible

[@SephirothRyu]

@@jonmab6990 The lag is absolutely tiny when compared to the lag of adding THAT many "extra" engines.

[@jonmab6990]

@@SephirothRyu I'm talking about when it's used at a large scale, such as an eve return mission. I'm not really concerned with smaller crafts

[@flafik]

Instead of using multiple engine stages you can use one line of engines connected using fuel lines and drop emty tanks, way more optimum and weight/lag reducing

[@Tzizenorec]

It pays to also drop some of the engines when dropping empty tanks. The only time you really need the extra engines is for getting into Kerbin orbit. Also... you don't really need fuel lines anymore. Just change the settings on the decouplers to allow fuel throughput.

[@MaxGuides]

It bugs me so much that you don’t just fire up all the engines on launch and use fuel priority to drop tanks.

[@petersmythe6462]

You actually can use the seat as the main control point. I do it all the time with aircraft, rovers, and really anything that needs to be small and lightweight.

[@macdjord]

One way you might have been able to save some parts: enable fuel crossfeed on the decouplers, activate all engines at launch, and ensure the fuel priorities on the tanks are set so the bottom tanks drain first. Then you don't need nearly as many engines on the bottom stages.

[@Jonah_Reed]

bro it's been 3 years since that update how did you not know that

[@chrisakaschulbus4903]

If you're making your maneuver node you can hover over another body (like mun) and see periapsis and apoapsis if your trajectory in close enough to it. You can even have this display toggled by right clicking on the numbers iirc. Then you adjust the node and see the values change.

[@ReidCaptain]

Didn't know it was togglable, that is handy. Thanks!

[@Radical_Larry]

@@ReidCaptain if you focus a planet or moon you're adjusting your encounter with and zoom in close you'll be able to see your periapsis and trajectory. Useful for making fine adjustments to your trajectory from far away!

[@TomClarke1995]

All I ever look at is the thrust to weight ratio and the Dv budget. That tell you whether or not you can get to where you need to go. Also helps to have a moon base to launch from.

[@thomasdepraetere2641]

Brother, spider engines probably don't eat much fuel, you could have gotten a small tank and ant engines for reduced weight more TWR, I got 2500 m/s delta V with the small fuel tank, and a pug engine for my probe. (You ended up doing that later, good on you) And why did you still bring a Kerbal if you had a probe core? Bruh, Kerbals have weight too.

If you find yourself using a bunch of the exact same engine setup and dropping tanks you should really set up fuel flow priority and cross flow and just drop the tanks and save yourself the weight of the engines.

[@iamnobody9001]

I struggle to get to Minmus and you come along and use those tiny engines to get to a planet I don’t think I’ll ever get to.

[@Backup_Punter]

Lol this is awesome. I have a challenge. to go to duna and land safely, and if your feeling up to it, return to kerbin

[@tales9476]

I wonder... for high part-count challenges like this - would it be better to simply enable fuel-transfer through the decouplers, and re-use engines across stages? You would probably need to add some fins to the bottom to stabilize the craft, but the weight savings from having fewer engines, plus the performance benefits of reducing the number of engines - I think it would work out better.

[@Known_as_The_Ghost]

Initial thought; No, because the ant engine isn't really powerful enough to lift its own weight on kerbin. 5 seconds later: "Oh, the spider. Interesting." Didn't expect you to make it! Also, 6:08 Pretty sure the reason for this is because your engines are shooting fuel directly at your own ship.

[@calesk536]

you can only use each part once

[@calebjosef6248]

I'm so confused about the mun encounter section. There is a maneuver marker to indicate your expected periapsis + it'll be concrete after you've done the burn - should be no need to "check" by warping close, and if you messed it up you can correct this type of thing with ~10m/sec of delta v Even on an extreme budget where the 10m/sec is too much to spend, there's no need to warp closer, your periapsis should be displayed! Above about ~20-25km is guaranteed to be safe, at least on the mun.

[@divizion8267]

[@admiralfluffy42]

I only watch this channel for the KSP content

[@KenJagers]

Instead of having ring after ring of engines, why not use a single ring of engines on the top stage. Then just drop the fuel tanks below them as they empty. Just rig fuel transfer so the bottom of the rocket empties first. That way you're not carrying the extra weight of so many engines only to drop them and ignite new ones.
