Why? It's fun and educating.

I was obsessed with it 10 years ago (aged 15 ). However, as I got interested with orbital mechanics and stuff and later KSP, I found 99.9% of the claims that everything is a hoax are just plain stupid and lack a single grain of science. Example: Apollo 13 did not have enough fuel to get to *Moon orbit* and back... It's ridiculous. Everyone who has been to the Mun knows what a free return trajectory is So, just out of curiosity, and for science, let's find out the opinions in this community

Squad: Hire this guy.

Is it 1:1 replica, especially the engines?

What is KIDS exactly? EDIT: The Isp scaled - got it.

Just finished my Atlas V 401 replica. The margin of error of this rocket is SO THIN! RD-180 shuts down at 4:10 seconds into the flight travelling at 4.5 km/s but the upper stage is so low powered that it actually passes Ap before reaching orbit, so it climbs up, then falls down a bit before the Ap rises back again on the opposite side of the planet... Just like in real life! Managed to put 6 tonne payload into low orbit but took me 5 attempts and several videos of real life launches so get it right! At first I was like - 'No way, dis ting should be SO POWERFUL' but after synchronizing with real telemetry everything matched up! Sooo like real life! Congrats again, Nathan! This actually can be taught in universities!!!

Mind asking what's new in v5?

I think he thought we are on v4 at the moment. This should be the changelog for the next release.

Yeeey. Do we need to delete something or simply overwrite? Edit: Archive 4 days old. Is that it?

10 tonn rocket: http://en.wikipedia.org/wiki/Vanguard_(rocket)

v5, v4? Still on v3 on the first page...

Which engines exactly?

I see Should try Atlas V replica today.

Where did you get the SSME from?

Nice to hear someone is working on the 'wobbly-rockets' problem. I mean yes, in real life they add structural reinforcements, all we can do is add struts which in most cases do not eliminate wobble. It's ok for stock KSP but something as large as Saturn V or even Atlas V is almost impossible with the same rigidity. Looking forward to it!

Exactly ! ! !

Step by step...

True that !!

Yes, it either leaves a huge gap or closes into a cubic shape like on the image above. Same goes if the tanks in both stages have the same radii. It just wants to leave a gap...

Screen of the problem:

I have no problems with struting actually. The problems lies somewhere between the stretchy tanks and the procedural interstage adapter. I tried playing with the radius of both top and bottom stage as well as the interstage adapter radius. I stack it - no problem, strut it, again no problem, but once I apply the fairings, they either don't touch the upper stage (there is a small gap) or, if I make it to touch the upper stage, the fairings shape like a cube instead of conical shape. Same problem is the fairings are parallel to the stage above/beneath. They just want to leave a gap and close that gap with a weird curved end of the fairing. It look ugly and creates more drag than it should. Probably its only aesthetic effect (not sure if FAR accounts for this), but its rather annoying and most importantly it DOESN'T look right.

Thats cool. Had struted the upper to the lower stage but not the decouplers. What about the shrouds? I tried the one from Proc Fairings but its quite buggy.

You should release those engines, asmi. Rd-171, Nk 33/43, add more real life engines like rd-180, ssme, j2,f-1, some real life strap-ons and you got one hell of a pack for this amazing Kearth mod. P.S !!!

Which pack are these engines from?

I'm having hard time with the joints between stages. Tried adding struts, they hold but the decoupler fails. Any tips for interstages?
