Replica discussion.

[qzgy]

Can't help but notice this is empty. So here's something to start

With the Making History expansion, a bunch of new parts have come out to aid in replicas. Feel free to share/discuss techniques that you have used for making your own. Or own variations even.

I built a replica Saturn V last night. I built it to look right with tank lengths that matched RL and the engines that were emulated. The J2 analog (forget the name) wasn't powerful enough for 5 of them to lift the second stage. I increased to 7 engines and it worked great. Also the Wolfhound is extremely powerful. I recall that the RL engine was also overpowered, but not sure how much.

I ended up with ~10000 delta-v - way too much for a munar mission. The TWRs worked great though...

• Stage 3 TWR = .65
• Stage 2 TWR = 1.0 (using 7 engines instead of 5)
• Stage 1 TWR = 1.2

The J2 analog seems to be under powered. I did the same thing building my Saturn V to look right. Five engines works fine if you dump a bunch of fuel from the stage's and I found I had more than enough TWR to lift a clasic heavy CSM and LEM combo mission. I'm trying this bare stock and had no KER to figure  TWR but I thought the Saturn Would fly fine. And my ridicules N1 clone would explode on the pad! N1 flew flawless fist time. 54 first stage motors lost 6 to fuel feed issue right after launch "didint even feel it Ha" .

I built a Saturn IB and a Soyuz-U for my Apollo-Soyuz Test Project mission:

So am I the only one who thinks the service module looks to long? clever trick with the three Mk 1s clipped inside.

I mentioned this in the Stage and a half thread in the Spacecraft Exchange, but I put together a 1.875 Atlas replica using mostly MH parts.

Yeah, it is def too long.

The stats on the Skiff and the Wolfhound are swapped. Use a single Skiff on the CSM; use five Wolfhounds on the Saturn second stage and one on Saturn's third stage.

Not to mention the added length you get when using 1xTS-25, 1x EP-25, and the full variant of the Wolfhound which has its own 2.5m plate on it.  They add up to be almost as long as a FL-TX220!

LOL...great catch!

You know, I've been defending @SQUAD's decision to charge for DLC. That backing was predicated on them releasing a quality product. I know they were really focused on the Mission Builder, but making parts correctly should be table stakes at this point - they've been doing it for over 5 years. It's a bit disappointing how many "simple" mistakes there are...wrong stats, off-center thrust...

Yes, I like making replica rockets that act in replica ways to recreate historic flights. I have done three replica projects so far with the new Making History parts. The mission write-ups can be found in the Mission Reports section of the forum (link below). So far I have done a Gemini/Agena rendezvous and docking, an Apollo Soyuz Test Project creation, and a Saturn V lunar landing flight:

So the Apollo SM is a little bit long, the Gemini SM is not the right form factor and a couple of the engines have the wrong Isp,  but it still works.  Squad said from the beginning that they were historically inspired parts, not replicas.

Well, it's not that a couple of the engines have the wrong isp; it's that two of the engines have all their stats swapped. Coding error, not design error.
