Umm, the ATV uses hypergolic bipropellants...

Attach some massless parts (I.e. ladders) radially to the engine and it will cool down.

With ARM parts, I'm planning on building 500 ton lifters.

The thrust is mostly dependent on the size of the combustion chamber, not the nozzle. The larger the nozzle the higher the exhaust velocity of the propellant.

From the size of the nozzle, it should have a max thrust of 1200kN and a vacuum Isp of 380s.

Strange how the advanced engine as lower Isp in vacuum than ASl, since it seems to be used as a second stage motor.

It should at least be blue.

I was slightly disappointed to find out that the clustered engines were one whole part. I was hoping that the small engines were standalone shuttle engines, which would make stock space shuttles much easier. :/ The engines are also way too powerful and the exhaust is all wrong.

This is what Tue whole rocket looks like:

This one's probably my favourite. All stock pico Saturn V.

Hmm.. I wonder if the big orange thing under the core stage is giant engine bell. If it is, I hope that it is a part on its own (not part of the adapter).

Hmm... The progress doesn't that the criss-crossing interstage between the capsule and the service module, as it is not meant to separate and survive re-entry.

So you're penalizing supersonic biplanes?

How does the R-2 have "excessive flight surface clipping"? None of the wings are clipped.

Four 24-77s on each booster and the core stage, two LV-1Rs on the boosters, and 4 on the corestage.

In the mk2 fuselage (in the middle of the plane).

I made an interstage fairing for my Soyuz 2.1b (in Pico Space Program). It made stage separation look really cool. It was built before 0.23 though, so the TWR wasn't tweaked correctly.

It was just a test save.

Last time I tried a k-drive, it corrupted my save.

R-2 SSTO A medium-ranged SSTO for beginners. Features: RAPIERs - for simplicity Reaction wheels Probe core Docking port Docking light RTG 64 parts Minimal part clipping (no cheats, some things can be attached if they are placed in the correct order. ) Flies great!

I have bad news: the file of final version of my entry got corrupted, and is now lost.

This one's from 0.19:

Well, it yaws as much as your plane with reaction wheels on, so I don't think it would be much of a problem. As an added bonus, I can fly it like a giant glider and perform sideslips while coming in to land. One problem I've been having is how it is laterally unstable due to the anhedral angle of the wings. The earlier spaceplanes were more stable, but I like the look of the current configuration.

Press f3. The wings might be colliding with the "launchpad".
