KSP2: SpaceX inspired reusable LKO rocket (with Duna mission)

So in todays video, i shoe-horn one of my ssrt LKO lift designs in to the weekly challenge, even if it stretches the rules a bit :P
I actually never done reusable rockets in ksp1, but the awesome new cargobays inspired me to make a couple of space-x like ssrt's
Craft file: www.mediafire.com/file/sl5gwx...
System specs:
3070ti
5800x3d
32gb ddr4 cl16
Timecodes:
0:00 - Takeoff
1:31 - Booster re-entry
2:49 - Suicide burn (booster landing)
5:02 - Duna intercept
7:22 - Duna takeoff and Kerbin intercept

I can’t even get close to the ksc from orbit, and you landed the booster directly on the launch pad! Awesome!

Kudos to you for trying that propulsive landing!

[@Kerman_von_Braun]

The trick to doing them is having kerbal engineer. You look at how much d.v you have and how much burn time you got. Then you look at your velocity near the ground. PE indicator should tell you how much time you have until you reach your PE, or when you hit the ground. From that, you can figure out how long you need to burn for :P So if your landing velocity is 250m/s, and you have 500m/s total d.v with a 10sec burn duration to use up all of that d.v, you would need to start burning when the PE timer is at ~5sec. Its not gonna be perfect but it will get you pretty close.

Fredbald Kerman clearly did not want to return to Kerbin.

I found an alternative to SSTO thanks to this video, i wonder : what are the engines use on this SSRT ?

[@Kerman_von_Braun]

SSTO's are still a lot more efficient since they can take advantage of the insane efficiency of jet engines :p Think i used 4 vectors on that craft. At least for this size, it doesnt make much sense to have dedicated vacuum engines since vectors are efficient enough on there own.

Where do i put the craft file? Nice designe and good Video, keep it up please.
