New version is out, now fuel infinite fuel.

Hmm, the online engine stack layout calculator I've created says it's not possible, not even with part clipping allowed, a central stack size of 5 m, up to 8 boosters allowed (in asparagus staging), and up to 8 outer engines around a central one on each of the central and booster stacks. Perhaps you should go for one of the part packs to have more engines available - I'd suggest NovaPunch. That said, 5 m is the maximum central stack size it allows, and it only allows the boosters to be up to 2.5 m in size. Of course in reality you are not limited to that.

I'd say file a bug report, with screenshot attached.

hey, are you stalking me? just kidding

That was Scott's entry to a reddit challenge: http://www.reddit.com/r/KerbalSpaceProgram/comments/1ezqjs/weekly_challenge_staging_mishap/

FWIW, I've made an online engine stack layout calculator than might come in handy when trying to design a lifter that can lift some arbitrary mass. Please see signature.

Not quite. Engine thrust does not depend on mass being moved. It's rather the TWR will go up with less mass, helping the rocket to lift off because of the lower inertia.

Now where have I seen that already...

That actually leaves a bit to be desired when using multiple engines on the same tank, for example when using my online engine configuration calculator. They way you would use it is that you create a tank, attach the suggested engines, then resize the tank to get the delta-v you need. With the bug still in, this would only work for the central engine (attached to the vertical stack node), but not with the outer engines (surface-attached). Of course one can work around that by putting a small pancake tank between the resized tank and the engines, then later attaching the engines to the big tank again, deleting the pancake. But that's quite tedious after a while.

I'll change it so that fuel is infinite. I didn't think anyone would run into this

Whoops, I must have fallen asleep. You are right, of course.

Thread title does not match post. Do you want to leave the Kerbol system or just orbit around Kerbol?

I believe this belongs to the Docking Tutorial rather than the Rendezvous Tutorial? Anyway, please upload a copy of your output_log.txt, thanks. Also, please try without any other mods to minimize impact when trying to reproduce the error.

This also happens when the tank is not the root part. Radially attached parts do not change their positions when the tank is resized. Only parts attached to the vertical stack nodes do. Workaround: Add a second tank resized to "pancake" size, attach your engines there. Then add another tank to resize on top of it.

Added 46 more engines to my engine stack configuration calculator. (see signature)

So I did. The calculator now has 46 more engines available.

Based on Temstar's post back on page 1, I've created an online engine stack layout calculator that does exactly that. Please note that of course it isn't perfect. For example, it does not take radially-attached engines into account at all. On the other hand, it finds a better solution for Temstar's example Over time, I will expand the calculator with more engines from popular packs.

Created an online engine stack layout calculator than can be used to configure central and booster stack layouts. Okay I didn't do that in KSP, but it's KSP-related, right?

Looking for a developer to take over this software! See this thread for details. Hi, based on Temstar's rocket calculation guide I have made an online engine cluster calculator: http://blizzy.de/asparagus/ This calculator can be used to configure an engine cluster layout for a central stack and attached booster stacks. It calculates which engines you need and how many of them, both for the central stack and the booster stacks in an asparagus-style staging. Please let me know what you think or what can be improved about it. Thanks!

Found another bug: When attaching parts radially or at the top/bottom (off-center), they don't change their position relative to tank size. This might not be so bad for parts attached radially, but for parts attached to top/bottom this is bad because there will always be a gap when resizing a tank, or they will clip into the tank when making it bigger. This does not happen when using the regular vertical stack attach nodes, parts will move with them.

I've actually never seen this before, this is the very first time. Oh, and it seems to be reproduceable with the craft there.

That's the plugin I've been waiting for. However, I think I have found a bug. I have an Apollo-style craft (craft file here *) that lifts off perfectly. The first asparagus stage also separates fine. But shortly before the second stage separation, this happens. It looks like some of the stretchy tanks somehow breaks and starts to stretch infinitely. * Note that you will need quite a few plugins to use the craft file. Posting it here just in case. Contact me for a list of plugins needed. Edit: I think the lines visible are 3 fuel lines and 6 struts, stretched quite some length. This conincides with the craft design. Edit 2: Just added another screenshot showing a closeup of the lander. The outer tanks are attached using 3-times symmetry, with fuel lines going into the middle tank. Please also note that the lifter section (not visible in the screenshot) does not use stretchy tanks, but only stock. Also on a different note, there seems to be some Z-fighting going on when attaching a LV-909 to the bottom of a stretchy tank.

You can just run the patcher.exe, it will update your game to the latest version as well as restoring missing files.
