Hobbsyoyo, you need to check out the Kerbal Engineer mod on the Spaceport, it is a plugin that gives you all of the data you are getting from that spreadsheet in real time, and if you don't mind using mods it is insanely useful.
Thanks dude!
I've seen that and I only didn't download it because I'm not sure how mods work with my Steam copy of KSP and I also don't know if it's still compatible with .22. Do you know anything about those issues?
My first attempts at the mega-launcher were all disasters. First off, some major new .22 specific problems:
What they didn't mention in the changelog is that they redid the Launch Stability Enhancers, they now have 100% more sag. I believe they used the same bugged 'squish' model that they applied to the landing legs. So now when you load a craft with LSE's, they sag under the weight. What's worse, they sag unevenly so your craft starts at a tilted attitude, and they also bob around. It's unbelievably annoying and I've heard of people having issues with them even on small craft. I know they want to make the game more sophisticated and realistic, but the one thing I don't want to ever have to deal with and plan around is LES sag. It's stupid because if that were a problem in real life, you'd just get bigger/stronger LES's.
SAS is glitchy as a mofo as well. I missed the fun from the initial .21 release where they had serious SAS glitches that they patched in .21.1, but from what I'm reading on the forums the new 'improved' SAS in .22 has the exact same issues that .21 had. For medium/heavy rockets that worked perfectly in .21.1, they are now completely uncontrollable. My huge rocket can't fly straight, even with tons of winglets and thrust vectoring. Turning off the gimbals on some or even most of the engines doesn't help, the SAS is just bugged.
The subassembly function is also buggy as hell. It wouldn't let me attach things I loaded from it to my rocket. I clicked and clicked and it wouldn't let me attach them.
Specific rocket problems (probably unrelated to .22): well it just breaks. Over and over and over again. This is the most heavily strutted rocket I've ever built and it just randomly breaks at random points. What's really troubling is that the failures are unrepeatable and totally random. What that tells me is that it's an issue with the physics engine rather than the craft. Which I can't fix.
I put the side tanks on the ICS up too high, I can move them down and it should help with stability issues but probably not enough to make it fly right.
They model the mass of struts now (they started in .19 but I didn't notice). It's pretty stupid to be honest because a short, .0001m strut weighs 100kg and a long, 15m strut weighs...100kg. Worse, the physics engine tries to accounts for any asymmetry due to your struts. So if you have one strut misplaced on one side of a 1000ton rocket, that's enough to cause a weight imbalance which leads to rockets wobbling off course which feeds into the SAS issues.
Also, my spreadsheet failed me miserably. My initial launch (before it disentigrated) actually got pretty far into the flight but I don't think it could have made orbit. It's possible that it could have and I will never know because it blew up, but to be safe I added more fuel and engines. I think the refit will get to orbit, if it doesn't blow up.
The good news: the aerodynamic nose cones do help with aerodynamic stability, I'm happy to report, but not enough to make it worth the weight/drag penalty, particularly on large rockets.
So yeah, I'm pretty frustrated with the game in general and with this patch in particular. Especially with issues relating to LES sag and landing legs sag, I just don't even know how that escaped notice in testing and they should have waited to release this update.
