Hi, I'm still struggling to get this MFMS trajectory into the Mission Architect:

If anyone with more experience would be so kind as to try it and tell me what the trick is I'd be much obliged. I've followed the steps in the tutorial as written, but it's just not working.

If you haven't done so, read through the Solar System Edge tutorial included with the KSPTOT download to cover how to use the Multi-Flyby Maneuver Sequencer with Mission Architect
If you have read the tutorial, then give more information on how you input and optimized the values from MFMS into MA and also provide the MAT file with your current results from these actions
So, I was following the Laythe tutorial. The problem with the Solar System Edge tutorial is that it relies on the optimizer to fine tune the flybys. That's fine, but when I try to optimize the second Eve encounter, rather than doing it with 1 revolution before encounter, the optimizer always ends up hitting it on the first orbit, simply because it can. After that, it gets stuck on the local minimum of burning straight for Jool from that second Eve encounter, rather than taking into consideration that it can get a free flyby assist by fine tuning the first encounter so that it only encounters Eve on the second revolution as it says on the flight plan.
I've tossed a few attempts at replicating the flight plan onto Google Drive if you'd like to take a look. The first is attempting to do it just like in the Laythe tutorial, with the initial orbit set slightly earlier and with a coast to the burn. The burn achieves the desired hyperbolic orbit out of Kerbin, but the transfer orbit ends up way off and never hits Eve. The second one I got rid of the coast and just set the initial state to be as dictated by the flight plan, but that one gets pretty much the same result. On the third, I tried simply setting the initial state to the transfer orbit at the time given for leaving Kerbin, but that one rams straight into Eve, rather than following the sequencer flight plan's flyby trajectory. That's not unexpected since I assume the departure time is supposed to be the time of the burn, whereas this is putting it on its transfer trajectory 10-20 days before that time.

Hi @Arrowstar
First I'd like to thank you for this great software. As someone who likes to relentlessly optimize every mission I run in the game, it's exactly what I've been looking for.
If you wouldn't mind helping me out with something, I've been trying to load this trajectory into the Mission Architect from the Multi-Flyby Sequencer, and for some reason it doesn't get anything even vaguely resembling the slingshots the sequencer gave. It doesn't even hit the first Eve encounter. If it helps, this was computed on the sequencer's default settings.

How do I slow my horizontal speed for a VTOL landing? The wings completely mess me up whenever I try to because the lift keeps me going forward...
-
Oh my god, the Mk. 2 looks amazing!!!! You are now officially my favorite spacecraft builder!
-
Heh, I haven't really ever flown stock crafts, so I wouldn't know.

Ok, I got around to test piloting it and I liked it mostly. I do have a few complaints though. The first and foremost is the lack of an ASAS module. It results in the craft requiring constant babysitting to fly straight, as well as making it far more difficult to successfully take of in VTOL mode. One other extremely minor problem is the unneeded fuel lines. Wings are fuel cross-feed compatible anyway, so the fuel lines do nothing but add drag. Now, on the other hand, after I added the ASAS, the craft was remarkably stable and could be left cruising with no problems, even at two-times acceleration. I did have a problem with the craft being slightly TOO maneuverable, in that it maneuvered so quickly that it was difficult to avoid over-steering.

It looks really nice, definitely going to try it. I'll report back here after I test fly.

Are there supposed to be 11 pairs of ram intakes, taking up the exact same spot?

For some reason the "S2 Fuselage Section 2m" part's model is 6 meters long as opposed to the correct 2 meters. The collision box is correct, but it looks just plain ugly when it intersects with other parts. Also, I can't quite figure out how to retract the "S3 Hypersonic Front Section" cockpit, can anyone explain the problem?

Hi, I've been looking at getting Matlab myself for a while, and if I already am getting it, I'm interested in compiling KSPTOT for Mac, since running it through a Linux VM has some performance issues for me. (I tried running it in a headless VM and using x-forwarding to hopefully solve the performance issues, but the MCR really didn't like that.) Could you tell me which MATLAB modules are used by KSPTOT so I can make sure I include them in my setup when purchasing?
