Thanks for downloading and supporting this mod!

Common Q&A:

Q: I have trouble installing this mod, missing parts, missing textures or sudden crash
A: Try following the installation section carefully, it's been tested working many times! Also try to run KSP in x64 bit.

 

Q: No fuel when right clicking parts in SPH/VAB!
A: Read the requirements and installation section of this post! This is most likely due to incorrect installation of Module Manager, or have multiple versions of it. Also be aware that OPT uses fuel switch, which means if you right click the part, you can select your desired fuel tank.

 

Q: The wing parts are very annoying to attach, could you combine them into a single piece?
A: I explained it in this post, why they must be kept separate!

 

Q: Help with building space planes?
A:  Basic Aircraft Design, this post provides good explanation about the basics of an aircraft design. Otherwise take a look at the pre-built crafts that's included with the download.

 

Q: The lifting body mess up during re-entry, causing the craft to flip!
A: check if your craft is well balanced on empty tanks first, then add fuel to the tanks near CoM. Also KSP aerodynamic model isn't exactly perfect, try keep re-entry angle less than 30 degrees. OPT parts have quite high thermal resistance, so unlike the real space shuttle, your kerbals will survive a faster re-entry.

 

Q: Support for FAR?

A: FAR is supported, however you need to download it separately for now. There is link on the forum page.

 

Q: Will this mod be indexed by CKAN?
A: Yes it's already on CKAN.

 

Q: The engines are overpowered!
A: If you dislike the engines, you can manually remove the engines by deleting the folder: GameData/OPT/Parts/engines. If you are looking for other large spaceplane engines, i recommend taking a look at: MkIV Spaceplane, and B9 Aerospace

ABOUT THIS LISTING

This page describes OPT Space Plane Parts V2.0 by kkgc3124. The description and screenshots are the author's own, imported from their listing on CurseForge on 25 October 2026: https://www.curseforge.com/kerbal/ksp-mods/opt-space-plane-parts-v2-0

Mythiq.net hosts no files for it. The download button goes straight to the release file on edge.forgecdn.net, so you are downloading from the author's own host, not from a copy of ours.

The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

GAME VERSION

Built against KSP 1.3. Parts and plugins compiled for one major version routinely misbehave on another — a plugin for 1.8 can fail silently on 1.12.

DEPENDENCIES

Many part packs and plugins depend on ModuleManager, and some on each other. KSP's loading log (KSP.log in the game folder) names the missing dependency when a part does not appear; the author's page lists the usual set.

1. Download the archive with the button on this page and unzip it.

2. Move the mod's folder — the one containing the .version file or the part folders — into:

Kerbal Space Program\GameData

The path in game must read GameData\\…, not GameData\\\…

3. Start the game. Parts appear in their categories in the VAB; plugins show their own toolbars or settings screens.

4. If the mod ships a CraftNote or extras folder, leave it — some packs store example ships and textures there.

UPDATING

Delete the old folder in GameData first. Two versions of one plugin loaded together is the usual cause of duplicate parts and toolbar errors.
