Hmmm, Ive done it with the TR-18D stack Seperator on a Skipper in 23.5

I'm going to devote a few hours to this soon. And write up exactly whats doable and whats not.

MJ

A few hours?! Wow, your weekdays must be fun.

Looking forwards to what you come up with.!

BTW, fantastic job on this as always, Rune!

Thanks for the hullage motors tip, I was unsure about the S-IVb and never noticed the thing about the S-IC. I guess perhaps looking to the wiki to build this would have been useful, but I just went from memory, and we all know internal memory is unreliable in wetware ^^'

I make out a small stack separator to hold your interstage fairing... doesn't that get very wobbly, or is it a case of "just add enough struts"? I'll try it anyhow, see if I can do the fairing-less trick with it, just have to measure radius again to place the fairing I already have, and I'll put the proper hullage engines while I'm at it Did you get a chance to try out the LEM and Apollo Spacecraft? I always like good building tips for the next version...

Rune. Thanks for the tips and kudos again you all! I know I sound repetitive, but they are always nice.

The stack separators are connected to the edge of the interstage(which is hollow), solely to reduce the gap between the stages.

I was also able to make the center engine shutdown automatically, for verisimilitude.

Update! I took into account your various suggestions (well, mostly yours, giggleplex ^^') and redid things a bit. I even gave a look to wiki, and now the paintjob is more accurate, the hullage motors are how they are supposed to are, and part count is pretty much the same. And rock-solid on first stage ascent! OP download updated and all that.

Rune. I still don't get what you did, BTW... care to PM me the file so I can get a look and perhaps learn something?

Oh this is amazing. Best Saturn V / Apollo replica yet.

People much much nerdier and geekier than us have already done the legwork...

If you really want detail then look here. (beware, too much detail)

Looking nice there Rune. Very clean and only 220 parts?. I`m at nearly three times that and I use mods. Aren`t the new parts nice

If you have turned the engines down then you could do the centre engine shutdown during the pitch maneuver that Apollo did (stage fuel 25%) The same happens for stage 2 also. Looking at the figures this is roughly Max Q (~10,000m) so I guess they did it to cut down on stresses during flight.

(they did some weird ISP changing fuel mixture thing too but the less said about that the better)
