Is this caveman Bonus only for using tier 4 parts, or also for weight and size restrictions?
-
It might help if you simplify and shrink the description.
Maybe have a specific payload to deliver.
Also allow only stock parts to make it more challenging.
Just some ideas

@Stratzenblitz75 might have something like this

Well, I did still have some fuel left in the tank on landing...
A bit more seriously, I do believe that at least my mass score is still beatable. If nothing else, replacing the Stayputnik with an OKTO2 should shave 10 kg off the dry mass and also allow the fuel mass to be reduced. With careful piloting, I think getting the total mass under 170 kg should be doable.
(Also, looks like you got my craft's mass wrong in the leaderboard: it's 187 kg, not 175 kg. That's a 12 kg bonus I haven't really earned.)
(Edit: You seem to have fixed the mass on the leaderboard, but now the cost is wrong.
)
Really good design. 166kg should be doable by optimizing it. Have just tried it, and was 15m/s short. This could be optimized by some Mun gravity assists and a good suicide burn. (which I didn't)

Congratulations! You have done the impossible

Granted. You are now the programm director of all TV channels. Everyone is angry and tries to kill you, because everyone wants to see other series which you have discontinued. Your series are continued but you don't have a minute to watch them.
I wish futurama was continued.

Granted. Now your spacecrafts explode outside of KSP. Before even loading the game!
I wish I had time for KSP
-
Granted, but it gets deformed into a disk instead
I wish there won't be people believing in flat earth (at least before this house asteroid incident)

Hmm. What exactly is in RP1 engine exhaust? Breathing the equivalent from a car or airliner probably wouldn't be advisable.
That's true, but they don't relate it to exhaust gases, they say it's because the space x launch damaged our universe

But even if a normal person is no expert in orbital mechanics... Why don't they just Google why it looks like this instead of explaining to the world why this can't be a rocket launch to space...

Im surprised so many people who live near Vandenberg Air Force base haven't got used to the launches yet. Why don't these people ask their more experienced neighbours? You'd think any normal person would ask the people in their surroundings what is going on rather than jumping to the aliens! conclusion.
They are talking to each other. There is a comment with lots of people living near there who all got headaches and other diseases while they were trying to create this interdimensional portal
One of my favourite ones is from a girl who says something like: even someone with the intelligence of a squirrel can clearly see that this rocket did not make it to space, because it did not fly straigt up but sideways.

I have no clue how I have ended up in this video, but I could not stop laughing about the comments
People think they are trying to open the door to another dimension when the falcon booster separates.
There is also a group which had all together headaches and other problems when this happened and others who are sure the aircrafts in the video are aliens picking something up
Others think they have bounced of the firmament while trying to pierce it
I can't believe that they are really thinking this... So I have to share it with you

That's actually pretty impressive . . .
You should use the Races! mod for timing.
Thanks for the hint, I will have a look at it!
Next to orbital racing, I do also have another type of racing, which will be released soon
-
Hello,
I have build this a long long time ago, and now finally found some time to release it.
The challenge is simple:
Download the track (ship included): https://kerbalx.com/KergarinAerospace/NG-Racetrack-1
Don't forget to bring a pilot! Use ALT+F12 to bring it to orbit ~2400km above Kerbin. Press 1 to release the ship.
Try to beat my (verry bad) time, or just have fun. The start/finish ring is lighted up in red.
(this can greatly improve you docking skills by the way)
You can also design your own ship or modify mine. It's a verry ugly basic RCS Racer.
Depending on how much interest this finds, there may come more tracks.

Well, it's no time to prove it yet
...
But I don't want to derail the topic because the challenge is clearly SSTO and not TSTO. I just wanted to share what sort of recoverable lifter design I would want to see arise from these Eve SSTO or general eve lifter suggestions/challenges.
Hope you will find the time and share your results

The following is not a SSTO from Eve surface. I'm not sure why one would even want one as the margins are to tight. I've seen youtube videos of people that already made Eve ssto's. Although I'm not sure if they cheated.
Anyway, I always thought of a TSTO system for Eve that would start at the lowest part of eve's highest peak on the equator (you know where)
Then accelerate with a second stage it carries up to 7km near the top of the mountain with decent speed (300-400m/s, MOAR) and then decoupler the second stage....
If there is a flaw in this KSP dream then don't hesitate to take me out of it. I only thought of it recently and maybe I'll try this for myself soon.
As I can say some did not cheat
300-400m/s in Eves low atmosphere already create heavy forces. Any sudden movement can destroy a craft easily, and I think it's also way to fast to open a chute. On the other hand, if you are at 300-400m/s you have probably not reached a height where more efficient engines start to work. This is just guessing based on my experiences, you are free to prove me wrong
But I think it is easier, to build a first stage which can push the second stage out of the atmosphere, and have a second stage which circularizes its orbit quickly, before the first stage re enters the atmosphere.
Something like this has already been done:
It's an interesting way, but I don't know if this is much easier than a low margin self refuelling SSTO.

LOL yesss
I don't remember exactly, but after 1.04, i was unable to SSTO Eve with my old ship... but when i tried again in 1.3, that was ok !
So i tried to scale down because the "vector" engine is exactly the same isp as the "mammoth", and because i wanted to try something new
BTW the weight is 4 tons for 1000 Kn on the "Vector", vs 15 tons for 4000 Kn for the "Mammoth', so on the paper the Vector is not so good... but in fact in 1.3, even if that's still very hard to SSTO Eve, i'm sure this is easier than in 1.04 !
The key is also to have the less possible drag, and the "Strake" wings seems to be very good for lift/drag ratio
My two cents...
I just did some tests.
Wings really work much bette now. At 7500 a verry low speed is enough to get airborne.
Maybe it can be scaled to a point where it can also reenter and land? A few more strakes are enough to survive reentry. But that's already to much extra weight to reach orbit.

Hi @Kergarin
The big difference with wings is that you can takeoff with a smaller than 1 twr... That's why i choose that ! as you can see, the twr of my "little" Eve SSTO is 0.86 at takeoff...
Hi @astrobond
so this turns into a Eve SSTO expert meeting, it seems Did you also experience wings working better on eve in 1.2 and above, or how were you able to scale it down that much compared to your old one?

This is Bradley =) The craft in that video works in both 1.1.3 and 1.2, but it works a shade better in 1.2 IIRC, I took some fuel out in the 1.2 variant.
Ah... Hello =) didn't know this, now things make more sense
Have found the chart i was talking about. It was not about pressure but about the mammoth engines thrust.
It's around 8% loss at launch.
I did not expect that the better workings wings can compensate this that well. But obviousley they do verry wellI should have realized this, wehen @astrobonddid build the smalles Eve SSTO i have seen so far. It's also a plane, and it Shows how small wings can be now
https://www.youtube.com/watch?v=8Q-PJ4FgWpg&t=34sSo Maybe you can even scale yours down now in 1.2+?
If i ever find the time for Eve SSTOs again, I will definitely also try planes again
PS: did you know about this? Was a little frustrating seeing this.
But great work anyway and thanks for the mention (I think you meant my SSTO?) -

I have a design i'm working on at the moment that gets a lot more payload to Eve orbit in one stage than anything I had achieved in 1.1.3. It is somewhat easier than before.
Vertical takeoff style is certainly harder than before.The pressure at the lower atmosphere was drastically increased in 1.2. I did test this with probes and created a chart. (will see if I can find it)
So the engines have less output and therefore a worse twr than before.
Also the drag increases, you have to deal with more friction and heat.
My ssto lander had a ridiculous amount of payload in 1.1.3. But in 1.2 it could not even make it to orbit anymore. Even not if totally stripped down.
So vertical takeoff is way harder now. I have to say, I did never test planes on Eve in 1.2, because I learned in 1.1.3 that vertical takeoff on Eve is much more efficient than SSTO planes in horizontal takeoff.
So maybe due to the ticker atmosphere wings do now have more lift, and maybe things have changed and planes are more efficient now, and maybe work even better in 1.2 and above than in 1.1.3?
How do you know it's 1.2 in the video? Or are you Bradley?

Months behind on this response, but this video WAS in the new atmosphere.
And yes, leaving an asteroid in orbit is roughly the same concept of leaving a fuel tank there, but I would like to think it was a fun loophole.
As to making it to Gilly from Eve on one stage, without refueling, it isn't possible unless a glitch is used. Or some kind of extreme lateral thinking solution. Using the conventional approach, I haven't been able to manage more than a few hundred m/s dV from LEO.Are you sure it was 1.2? This was made really shortly after the release.

Let me throw in the first SSTO.
You asked for tier 6 or 5 with bonus. What if I do it on tier 4?
Album:
https://imgur.com/a/CIOURPf
4 toursit seats
30 parts (could do 29 without the luxury of an escape pod and perform even better)
tier 4 parts only
wet 15.035
dry 13.474
1.561 for fuel + 1.347,4 for airframe depreciation = 2908,4 / 4 tourists = 727,1 / per Tourist -10% = 654,39 points
Or is there a tier 4 bonus?
