See this explanation (emphasis added):

By "fixing" that exception, you introduce unintended behavior (making a part appear that is supposed to be hidden). In reality, rather than depending on MoarFEConfigs, this mod conflicts with it. But it may be possible to avoid that if a better method was used to achieve the same thing, as in:

Almost don't appear at a first look... but is here on red indeed

Very interesting with the two fins only. But if that's how they wanna do it I'll do it too! Release soon.

The most important function of the 4 Crew Dragon 2 fins are to provide aerodynamic stability during an abort mission.

But with only 2 fins and some software updates, its possible to make them work as 4.

Don't think you'll get decent aerodynamic stability with 2 fins only, that thing will just yaw away but I'm not an expert on aerodynamics (yet).

Not that it matters anyway since the Cargo Dragon 2 won't have active abort ability with the removed super dracos and the trunk will still have 4 fins for Crew Dragon. The two fins here are simply to provide more (the same) area for the solar panels.

Hello @Kartoffelkuchen

I can clarify that, sometimes there are a bit of confusion about that.

The Cargo Dragon version, don’t have SuperDraco engines, because it don’t have Launch Escape System (LES).
The SuperDraco engines are being used on the SpaceX Crew Dragon 2 only, in LES, designated in SpaceX as "SuperDraco launch abort system".

This System in mandatory for a NASA crew mission.

What is disabled for NASA flights, is the vertical landing system which allows the Craft to land vertically, that was replaced by the Drogue chutes and the Main parachute with Mark 3 design.

But the vertical landing system can be certified if some customer is interested on it.

The Draco engines are used for the ISS orbit injection fine tune approach and ofc that the Draco thrusters are also ignited for the de-orbit burn.

About the "SpaceX Falcon Heavy v1.2 Block-5" the last craft was updated, along with all other parts and pieces need for the demos, several details to improve the R.O. configs.

Realism Overhaul Configs [WIP]

pmborg · October 23, 2020

Hello,

I have done an almost final version for this release 1 of the Realism Overhaul Configs [WIP]

All phases of flight now have a tone/ring to highlight a phase change in flight.

etc...

Thiemenator · October 24, 2020

Hey, could I get the source files for this? Me and my friend are trying to make an 'improved' IVA for Dragon. We can't unscramble the .mu files nor put the png into a 3D model convertor. Cheers

pmborg · October 24, 2020

Hello @Kartoffelkuchen,

While I was reviewing all in detail found an error in falcon 9 fairing mass.

I added the fix in a cfg file:

//Falcon-1 mass 0.136t
//Falcon-9 mass 1.7t
//Falcon-Heavy mass 2.0t
@PART[KK_SPX_FalconPayloadFairing]:FINAL
{
	@mass=1.7
}

linuxgurugamer · October 25, 2020

I'm seeing the following error:

PartCompiler: Cannot clone model 'Launchers Pack/Rockets/SpaceX_BFR/KK_Raptor/KK_Raptor' as model does not exist

~~I don't know if it's a typo or not~~

Looks like the mu file is missing

I dug a bit further, I did find the Raptors under SpaceX_ITS/Raptor, so maybe it's a leftover config?

Hello,

[1] I am still working hard, on "RealFalcons-v2 RO" for KKS SpaceX Pack.

With optimized maneuvers and flight profiles in KOS, I could save 1.5k delta-v, for the initial landing maneuvers,
enouf allow an optimal "suicide burn" with a few meters of margin.
I reduced the amount of fuel need in general, optimizing the rockets in all family with accurate values.

I will update the Dropbox link soon, with the new updates.

An image for now, from one Stage-1 of Falcon Heavy landed on Landing Zone 2:

NOTE: final delta-v 13m/s!

[2] Also updated the fix-kerosene-density.cfg

This fix was important to mach the values with real values.

Hello,

Currently the KOS code work, but sometimes, there are some things that don't work exactly as I want or it is supposed to be.

I have done like hundreds of failed landings before getting into this point, showing on next video: (after booster separation)

It works but some details are not quite right yet...

I want to stop rotation
I want to stop the legs from skiing/slipping after landing.
I need to do also the GSO satellite deploy for now only LEO is coded.
etc...

I am estimation one or two week's after that probably, I will put the code on https://github.com/ and call it Release 1, and then the future changes will be from there.

What about falcon heavy boosters, they will be landing at the same time?

The ideal thing would be each booster run their own code, like they are doing, but once in KSP have a limitation that only the active vessel can target a "target", and that is the base of the code, with this limitation will not be possible to land them both in current KSP versions.

But I will try anyway to do something about it, or at least I will try to put the other stage as a slave of the main one, (but this is not what happens in reality.)

But this detail once is hard to overcome is not a priority in the agenda.

This is the problem of slipping , after landing:

It seams that the solutions that work in terrain don't work here because rocket is in touch with another vessel (Landing Zone 2):

I think that the solution that @allista use for anchor hangars, might also solve this problem, any other ideas?

Ok, thanks for your answer, if you need testers you can contact me for testing purposes

pmborg · October 31, 2020

Fixed another bug related with that sometimes... the side boosters of falcon heavy were rolling after separation and because of that sometimes collided main core:

Bug:

{
	update_phase_title("[2] Sleep on Separation        ",0).
	unlock throttle.
	UNLOCK STEERING.
	SAS OFF.
	stage.
	shutDownAllEngines().
	wait 5.

	update_phase_title("[3] STEERING RETROGRADE   ",0).
	SAS ON.
	AG6 ON. //retrograde
	set sasmode TO "RETROGRADE".
	wait 1.
	LOCK STEERING TO SHIP:RETROGRADE.
	wait 3.
}

Fixed, a small thing made all the difference:

{
	update_phase_title("[2] Sleep on Separation        ",0).
	unlock throttle.
	UNLOCK STEERING.
	SAS ON.
	//RCS ON.
	stage.
