Okay, thank you all, but what are you talking about are powered descents. I would like to with parachute only descent. Meaning that I would only burn a little to bring down periapsis, and from there on, descent only using drogue and main chutes. Carrying engines and fuel for powered (or partially powered) descent adds a lot of complexity, weight and cost...

Hello, I want to create a Duna base in career mode. Obviously, the parts will be landed separately on the surface, then moved closer and docked together. For that to happen, I need to land all of these parts (and later, other parts when expanding) very closely together, no more than several hundred meters apart. How can I achieve that? MechJeb has landing autopilot with atmospheric reentry predictions, but somehow it often puts estimates wrong, as far as 30km from chosen landing spot. Also, it doesn't account for drogue chutes, which are kind of necessary before deploying the mains. How do you do it? What's the proper way?

Okay, I see, so how can I fix roll stability then?

Hello, In KSP 1.04, I'm trying to make SSTO spaceplanes. I have already made 3 or 4 successfully. I always use MechJeb autopilot. The problem I'm having is that sometimes, my planes do not have enough roll stability. Meaning that even a slight roll movement will make it roll from side to side, and MechJeb autopilot is unable to "calm down" these roll oscillations. I usually have a big wing aft will ailerons (that control roll and nothing more), smaller elevators at the front of the spaceplane (control only pitch), and and rudder at the tail that controls yaw. What I've tried already: 1. Making ailerons smaller or larger; 2. Moving them closer or further from the centerline; 3. Making main wings at an angle (slight V shape). Sometimes the plane has roll stability, sometimes it doesn't. I can't pinpoint the exact cause of it, and I've been guessing for weeks. It's a bit of shooting in the dark now. Can anybody help?

Okay, thanks, but how can I then add some of these icons to Toolbar mod? For example, Contracts, and like Trajectory Planner? They don't show up in the list.

Excuse me for this probably very stupid question, but how can I hide the default toolbar (in the upper right corner when flying, lower right when in VAB/SPH)? There are a clutter of icons (both from native game and mods) that I'd rather not see (or have them only in custom toolbars of this plugin). P.S. Also, how can I add custom buttons from native game to this toolbar? (Like Contracts, Resources, etc)

I have a generic ascent profile which works well for me: pitch down 2 degrees every 1000m. So at 1km you pitch to 88°, at 2km - 86°, and so forth. At 30km you'll have 30° pitch, hold it until apoapsis reaches 70km, then pitch down to 0. Burn until desired apoapsis is reached, and do circularization burn. Works for most rockets I designed, gives a very smooth ascent.

Wow. This is really smart. Worked like a charm. Thank you!!!

I know, but I don't think it accounts for multiple orbits. In certain cases, yes. My example. I have a ship in Moho orbit that I'd like to return to Kerbin. Time frame isn't of importance. Now, to minimize dV, I have to burn at Moho periapsis, and raise apoapsis just to touch Kerbin orbit. However, the Kerbin will not be there at the right time. So, I coast to apoapsis, and then adjust periapsis just slightly so that I intercept Kerbin again at apoapsis after some orbits (usually 3-4). This can be much more fuel efficient than usual Hohman transfer. But for it to work, I need to see predictions for future orbits, not just this one.

Hello, I'm using KSP 1.04 with Mechjeb 2, KSP Alarm Clock and several other mods. I'm now into advanced interplanetary trajectory planning. Could someone please tell me how can I set up a maneuver so that I see target intercept predictions after more than 1 orbits? What I mean is that I burn now, but intercept target planet after, let's say, 3 or 4 orbits. Right-clicking maneuver node and clicking "add" button only delays the maneuver itself, not the predictions. KSP Alarm Clock can check target distance up to 20 orbits, but it doesn't work with maneuver nodes and planets (only vessels). The point of doing this is that it might save a lot of fuel in some cases (like returning from Moho). So, how do I do it?
