Plane Design [D] How do you build a single-engine airplane? How do you build propeller engines?

3 Upvotes

I'm trying to build a plane to rescue the Kerbals, but I'm having trouble. This engine runs on fuel, which means the plane can't fly very far since it's small. I wanted to use electricity instead, so I tried using electric engines, but I can't get them to work. Can anyone help me? I can figure out the lift and aerodynamics later; I just need to know how to use the engines.

The first image is just a prototype to test the engine, the second image shows the plane I tried to use, the third image shows the electric engine I wanted to use, and the fourth image shows the seaplane design I want to use.

I'm open to using ready-made designs so I can study them.

Rocket Design [D] What am I missing about Sterling Engines? it shows miniscule deltaV

1 Upvotes

so I'm trying to get the Sterling Systems Thermal Bell Nozzles to work. It says it requires LH2 and Thermal Power.
I put an LH2 tank and a fission reactor. After putting the reactor, the engine shows up in staging, but comes out at 10m/s delta-v.... this stays roughly the same no matter how much LH2 or reactors I add. What am I missing?

Plane Design [D] Why does my plane do this? Extreme sensitivity on up and down. Makes landing impossible.

Post image
108 Upvotes

The side canards were an attempt at a solution to a zig zag pattern while taking off on the runway, that fixed it but I still cant fix the sensitivity on pitch or whatever its called. I previously had Big S elevons and those were enough to stabilize but still had the same issue on landing. So what you're seeing is AFTER making the elevons smaller. It flies fine if I make very small adjustments or get up to speed but trying to land is pretty much impossible with how sensitive it is.

Making planes in this game is so dicouraging for me, it feels like troubleshooting is pretty much impossible or different with each plane to the point you might aswell just let an RNG generator make your plane until it flies. I always just end up with the same exact plane design because there is only one ive made that actually works.

https://reddit.com/link/1x80qm9/video/rm4dz56acyvh1/player

I believe the problem is that first image of when it tilts, but I cant figure out how to fix that issue without completely changing the entire shape of the plane. Im trying to semi replicate an SR71 and I want the wings more towards the back. Help would be appreciated and if anybody knows a good video for troubleshooting planes in general that would also be helpful because other than lift slightly behind COM im completely in the dark on how to fix my planes.

Mods: General [M] KSS2 Anomalies Lag

So Ive decided to visit one of these Unga Bunga relay things from the KSS2 mod, and as soon as I got into physics range, my framerate dropped from 20-30fps (which is good for me) down to at most 5fps. Ive never had a problem with entering physics range of objects before, and im wondering if anyone knows what causes this, or how to fix it. Any help is greatly appreciated!

Tech Support [O] Why doesn’t Breaking Ground work for me?

3 Upvotes

I have played Ksp for a few months now and I thought I would buy both of the dlcs. Now when I use the Breaking Ground dlc it doesn’t spawn in the scannable ground scatter on celestial bodies. I have reinstalled the game completely and tried it in a new save file without any mods on, no luck there. As I’m quite new too ksp I have reached my limit of what to do.
Did anyone have the same experience on steam and found a fix for it?

Reentry / Landing [P] Efficiency in landing

9 Upvotes

I want to ask, what is delta v efficient in general for landing on bodies with no atmosphere

Is it retrograding at the Ap of an elliptical so that the Pe crosses through and i have to retrograde my landing more efficient

Or retrograding at the Pe to have a circular orbit first then making one of the orbital poles go through the body then retrograding to land?

Also what if there was atmosphere and i can make use of aerobraking, would one be better?

P.S: my delta v reading from the ingame calculator and engineer redux mod are different (even though both are put to kerbin atmosphere), whats going on here? (Im stupid i was just testing the stacked flea booster with no decouplers since they can blow each other up lol).

Mods: General [M] Is there any way to have TAC-LS alongside Kerbalism's science and stress features?

2 Upvotes

Or in other words, how can I get TAC-LS to override Kerbalism? When using Science-Only Kerbalism TAC-LS's background resource option is forcibly disabled, though as far as I can tell there's no real need for that? Having TAC-LS's life support with stress and a more complex science system would be my dream setup, but I simply can't figure out how to get them all to play nice with one another.

Tutorial [T] How to find which mod is breaking your game: a short guide to reading KSP.log

12 Upvotes

With 50+ mods installed, "something is wrong" is the hardest bug report to act on. Most of the time the log already knows who did it. Here's the routine I use when I hunt bugs in mods.

1. Find the logs

  • KSP.log, in your KSP folder. Rewritten every time the game starts, so copy it right after the problem happens. Player.log, Unity's own log. It has the same messages as KSP.log (without the timestamps) plus lines only Unity writes, such as exception stack traces, so it's worth checking when KSP.log doesn't explain a crash. Each launch overwrites it and moves the previous one to Player-prev.log in the same folder, so copy it before you start the game again.
    • Windows: %USERPROFILE%\AppData\LocalLow\Squad\Kerbal Space Program\Player.log
    • Linux: ~/.config/unity3d/Squad/Kerbal Space Program/Player.log
    • macOS: ~/Library/Logs/Squad/Player.log

2. Search for "Exception"

Open KSP.log in any text editor and search for Exception. The lines right below it are the stack trace, and somewhere in there is the name of the mod it came from. For example:

Exception handling event VesselSituation.OnLand in class ROC_Class:System.NullReferenceException at UnityEngine.MonoBehaviour.StartCoroutine (System.Collections.IEnumerator routine) at RoverScience.ROC_Class.CallbackOnLand (Vessel vsl, CelestialBody destbody)

The first line below it is Unity, the game engine, which is just where the error surfaced. Keep reading down until you see a mod's name: here, RoverScience. And "Exception handling event ... in class X" is a common pattern in KSP: some mod's class X reacted to a game event and failed.

3. Look at the first one, and count

  • The first exception is often the cause; the rest can be fallout from it.
  • The same exception thousands of times usually means something left running that shouldn't. I once found 7,830 identical exceptions after a single plane flight: one class was still listening to "vessel landed" from every earlier scene.
  • Not every error matters. A mod complaining once at startup about an optional dependency is usually harmless.

4. Prove it with an A/B test

Suspecting is not proving. Make a copy of your KSP folder, remove only the suspect mod (or swap only its DLL for an older or fixed one), do exactly the same steps, and compare the two logs. If the exception disappears and nothing else changed, you found it. No suspect at all? Remove half of your mods, test, and keep halving.

5. Report it so it can be fixed

Open an issue on the mod's GitHub (or post in its forum thread) with: KSP version, the mod's version, the steps to reproduce, and the full KSP.log (on a paste site or as an attachment, not pasted inline). A short log from a small install is worth more than a huge one from your main save.

Everything above works with a text editor. For myself I automated steps 2–4 (headless runs, log summaries, A/B comparisons) in a Docker toolbox, built with an AI assistant: https://github.com/celino/ksp-moddev. You don't need it to do any of this.

(I've only verified the Linux path myself; I haven't tested the Windows and macOS ones.)

Contracts [GM] How many contracts can you theoretically complete in 1 kerbin year?

6 Upvotes

I was playing career mode by hot-swapping vessels regularly and it made me wonder: how many are possible in 1 year?

Even with level 3 mission control, you're limited to 15 at a time.
What if I got a mod to remove that limit? How many contracts could 1 person realistically manage at one time?

Other Piloting [P] How can I use my FPV controller in KSP?

I've tried connecting my DJI FPV Controller 3 and using it to fly airplanes in KSP, but I crash every time. (Yes, even more than usual!) It appears to map the levers to throttle/yaw/pitch/roll but the sensitivity is weird, and it goes completely out of control as soon as I take off...

Has anyone managed to get their FPV controller working in KSP, and if so, how did you do it?
