request for a 230ton lifter

[Spartwo]

can anyone help me get a 230 ton payload into orbit.I got close but it kept exploding in its second stage.

here`s the craft http://www./download/0kg717f5cwx6dmn/multidepot.craft

only pic at the moment

Stock only or?

Stock only or?

stock only.It`s a fuel depot by the way.the craft has no mj

EDIT:better picture

Okay, cause I saw MechJeb and I had a two second loading as it clashed with the stock tag lol

[stupid_chris]

Well that's large. Everything goes to space? No decoupling excepted the SRBs?

feel free to remove the launcher

I'm quite confused on to what is the launcher exactly. There's this decoupler above as I see, I removed it along with it's laganauth, and what's under weights ~205t without the SRBs, I guess this is what you're sending up there? What seems to be a tug coupled to a station core/fuel depot?

the problem is that it's not really a payload that can just be slammed on top of a rocket, it's just not made for that.

stupid_chris, could you, please, provide a screenshot of the payload? Kaspersky blocks .craft file for some reason

[Spartwo]

Imgurs back so this is the payload

Try the T-9.

Should be able to lug 230 to LKO... although im not sure. It can pull a lot though. Yeah should carry that payload. But you might want to make two trips instead of one large one.

I have a working launcher, I'll make sure it works fine and upload.

I prefer to dump all the "stored" fuel before i send my extra large & low part count permanent fuel depots into space. They need to be refilled some time anyway and doing it earlier can also show off potential design flaws.

Say, that's a brilliant idea.

I once made a lifter that could carry 250t to orbit(just a bunch of fuel tanks) but I couldn't build a payload that was stable enough to actually launch.

[BigDog]

I have a fueler design that the payload weighs in at around 340 tons, it is 8 orange tanks plus 6 T-800s with LVT 3os for maneuvering. What I found I had to do was throttle back to 3 tick marks from full throttle and wait until about 15K before slowly doing a gentle grav turn. I also added some SRBs on "outriggers" large I beams up high on my payload to reduce some of the pressure from the bottom. I went with SRBs because their thrust is a fixed amount, and to keep the part count down over tanks and engines. Anything else and I would get the explosions you are talking about. So what you want to do is doable it just may take some more time to find what that design specifically wants as far as throttle settings and flight profile.

[Spartwo]

glad it`s doable.I just can`t get by 150

[BigDog]

Looking at what you posted in the OP, I would add some T-800 tanks with LV-T30s, either aspargused or onion staged to the orange tanks. These are less weight and empty quicker. I suspect though, since you said this happens on a stage that you need to reduce your throttle some. Also look at the flight report after the failed missions and determine if you need to add more struts. On my heavy fueler there is probably enough weight in struts to build a Mun capable ship. Again such is doable, it just takes quite a bit of trial and error.
