Sorry if im being rude. I really need to do my things for school. I will post the vid of whole process later.

Also i suggest to make an app of this.
That's fine, we can wait for that. Even just a screenshot flying and one in orbit.

I'm not sure how screenshots of assembly are within your time frame, but screenshots of it in use aren't.

I mean, you've built it, so you must have flown it? Unless it's untested?
 
Sorry for waiting. Here is the mission itself
Liftoff

Its heavy you can say by velocity

Main engine cut-off

Escapeing the atmosphere

Second stage cut-off
Screenshot_2020-10-14-13-37-42-28_cba7b177b2edecae2cc69ac3f7d2b91d.png

Lost some speed
Screenshot_2020-10-14-13-38-47-32_cba7b177b2edecae2cc69ac3f7d2b91d.png

Needed some more fuel from payload

And finally in the LEO!

Thank you for your patience and understanding ☺️
Hope you like it. (Updated second and third stage)

But payload isn't full fuel.

Redesign the rocket so that the 1000t payload doesn't have to be used at all before you get to orbit, then it will be legitimate. :)

Tip: I think you were going up from the launchpad too slow, wasting fuel on combating gravity.
Try to reach over 100m/s by the time you reach 1300m high. If you go faster and turn more, maybe you won't need as much fuel to get to orbit.

I appreciate your reply, but i really dont want to make it worse by redesigning it. Also it can carry 1000 without using extra fuel like i said if you fly it perfectly

You mean better by redesigning it. It's not about perfect flight, it's underpowered and you've burned a large amount of your fuel (15% of the first stage) before it's even cleared the tower. If that is a one kiloton fuel block and you've had to eat into it to get into orbit, then a good flight isn't going to save you that 150t+. Only a re-design will do that.

It's not a bad rocket as a rocket doing rocket things. But it's not capable yet of putting 1000t into LEO, so isn't a kiloton lifter. That's not anyone having a go or being a dick, it's an objective standard.

Ha, I wish I was that fast, that high. I barely break the sound barrier by 10,000metres.

Still, your payload is 85% full, you're short by 150 tons. It's not negligible. Mooncrasher's advice is good. If you bend your trajectory sooner, you'll increase your horizontal speed earlier, and you can save significant fuel that way. Don't worry too much about drag, it decreases quite fast with altitude (the air pressure halves every 2200 meters), so it's quite low above 10 km, and it's negligible above 20-25 km. Trying to reach the 30 km mark before building your horizontal speed is a mistake, you waste a lot of fuel that way.

Hehe.... Am I kiloton lifter now?? :) :)

The grid...

Some trial and error paid off.....

Oh i lost one Titan engine on 2nd stage due to stagin process (aero)

And other two managed to fly it until to orbit...


Is it passed???

A bit further than I expected.
Didn't get to the moon, not that I thought it could.

If you sacked all the un-used at launch frontiers and just used the blocks as dumpable propellant canisters, you'd get quite a bit further

It's all about minimising dry mass and frontier is a lot of dry mass

I guess I'll make an improved version. This was a test-version.

I would hazard a guess the core first stage burnt out before the side boosters did. This is also dead mass you're dragging around. Or sack the separator between them and have all those engines access to all the side booster fuel.

That'd mean you wouldn't have to light the pod frontiers after the core burnt out as you'd run out of thrust at that point
