Return boost alternative Hi, I don't know if this tutorial is finished, but isn't it better to burn prograde when you are between Mün an Kerbin? Thank you for your interest in my tutorials. That actually depends on if you ended up on a prograde or a retrograde orbit around the Mün. When you are retrograde, it's best to accelerate at the most distant point, while when you are prograde, the most energy-efficient point is the point where you are closest. I should mention that. In the screenshot, I can see you've got rockomax connectors on stage one connected to stage 2 as well, it seems, although we aren't instructed to do this at all where there aren't any listed in the instructions, among other things. If I use ONLY the parts you've listed, following your instruction, I get an incredibly unstable ship that can't make it into orbit without disaster. Is there any way you could improve the instructions for building this ship, and perhaps include the parts in the screenshot? The way it is now, I can't seem to even get the ship built yet, and I really want to try out this mission. Thank you very much for your feedback. Could you publish the. That would help me much to spot where the instructions are unclear. I hope that this was the reason you couldn't replicate it. Otherwise please post your. Take a look and let me know where I failed miserably: mediafire. Your main mistake was that you used to link the four outer rockets of the 2nd stage to the central rocket. They are supposed to be attached directly to the central rocket. I've built it and get it into circular orbit, but it seems I'm missing a decoupler somewhere during the docking stage. Mind giving it a look? So in the instructions during the docking phase, you specifically say not to use the stack seperator - but that is the only way to seperate the CMS from the LM, and of course using the stack seperator results in a very difficult docking procedure due to an extraneous piece that comes off which blocks the CMS from the LM. Should I add in a decoupler to the docking port just beneath the stack seperator? It just seems there is something missing from the tutorial. Been enjoying going through the tutorial series; the Gemini 6A and 7 mission in particular really gave me a sense of accomplishment... Anyway, I too have been having problems with getting the Saturn V replica into orbit. Granted, I've only tried two launches so far. I had a structural failure on the first stage during the first launch resulting in catastrophic mission failure saved the crew ; I replaced the TR-18As with Rockomax Brand Decouplers between the first and second stages and I replaced the TR-18A between the second and third stage as well since that's how the picture looked. Second time the structural fault occurred at the TR-18A holding the third stage to the LM after first stage jettison, also resulting in catastrophic mission failure saved the crew again. Any thoughts on what may be going on? I'm not in a position at the moment where I can post my. Make the gravity turn gradually. If faults keep on happening, figure out where in the after-action report and shore it up with more struts. Learned a lot about the nature of docked ships that way, actually... The lowest stage has 3 fuel tanks in height, and then an engine. The lowest tank could be placed, but it was heavily clipping through the floor. The engine could not be added at all. I've managed to build the middle part of the first stage without the tank clipping the floor. There was only a small gap left, but I managed to get the engine underneath. For the outer parts of the stage I had to copy the inner part and move it a bit lower, because the Decouplers would have collided otherwise. In that case the tanks and engines were in the floor, but on the Launchpad the rocket was above ground again. If the problem you have is about the middle part, you should check if you accidentally put in an extra decoupler or used a wrong engine somewhere. I started with the Command Module, so to move the ship up, I have to grab that Command Pod to move it. Did you possibly start with the Landing Module instead? I was not able to get either the middle of the ship or the outside portions on. I'll give it another try tonight. I don't really know what I may have done differently, but it just won't fit. During launch, I don't seem to have enough stability to keep the nose pointed correctly, and the rocket starts a strange bending oscillation that amplifies to the point where the support struts rip off the protective nose cones and some fuel tanks with it. I can never get above 10k before I end up fully pitched over headed towards the ground. I have tinkered with the canard placement to see if it was due to lack of control authority based on the positioning on the 1st stage. I have attempted launch with and without RCS, with and without SAS, and with and without autopilot MechJab. I am not certain how to post the. BTW thanks for these tutorials--they've been really fun! I have the same problem. It seems so unstable that I can't get it into orbit, but maybe I'm doing something wrong. Here's a craft file: 06:46, 24 July 2013 CDT Hello again - quick update for 0. I've been having issues with the design again; it still telescopes the stack in the second stage more often than it makes orbit. I'm thinking about doing a redesign to put Skippers on the second and third ascent stages to see if that will help it will reduce the TWR on the second stage to just under 1. I'll let y'all know how this turns out; if it doesn't solve the problem, I might try an action group to lock the gimbals on the outboard engines of the second stage next. I'll keep y'all posted. Further, new stock parts enable the lightening and shortening of the stack to provide better performance, fuel efficiency, and control authority. Be careful not to obstruct the hatch! I posted that reddit question -- 08:40, 12 August 2013 CDT.
