When a plane is at high altitude and intake air runs out, the jet engines don't all cut off at once. One will cut, then another, then a third, etc, causing uneven thrust. Could this be your issue?

Edit: Ignore this post, see below.

Well, what kind of rover are you looking for here? Something small, Jebediah's First Rover style? Have you landed rovers on the mun before? There's a ton of variation in rovers.

Do you have a picture of your craft?

When lifting heavy loads, asparagus staging is your friend. In short, you use a ring of fuel tanks and engines around a central core that drain two by two, dropping each booster as they empty. Here's a diagram: The blue circles are fuel tanks with engines and the yellow arrows are fuel lines. All engines draw from the outer two tanks (the ones labeled S4). When those tanks are empty, they are decoupled and the remaining five engines all draw from the S3 tanks, and so on. To see an example in action, check out the stock craft Kerbal X, available in the VAB in sandbox mode. Good luck!

Here's a good tutorial on getting to Duna: http://wiki.kerbalspaceprogram.com/wiki/Tutorial:How_to_get_to_Duna You should be able to adapt it to your purposes. One note: Always pack more fuel than strictly necessary, especially if you're inexperienced in these things. Having an extra margin of delta-v can be lifesaving. As for orbital construction, it's not strictly necessary but I would recommend it. I've seen people do return trips from Eve with a single launch, but that takes skill and luck, and besides, constructing a ship in orbit is super satisfying! My Duna ships usually consist of a lander, an engine block, and a fuel block, but you can customize to your heart's content. Good luck!

To clarify, the control you're probably getting even with no control surfaces is probably coming from gimballing engines and/or torque applied by the command pod.

Doing this near the surface is called a "suicide burn" and is actually one of the more fuel efficient ways to land. Doing it a bit higher up give you more margin for error, but do it too high up and you'll just have to do it again later as the planet rotates under you. For someone having trouble like you are, I'd recommend killing most of your velocity a few kilometers up (anywhere from 5 to 25 depending on what you're comfortable with/how fast the ship can accelerate) and falling more gently to the surface, making smaller correction burns retrograde on the way down. Pack some extra fuel when you do it! Oh, and protip: if it looks like you'll be hitting the ground with too much velocity, don't be afraid to floor it for a few seconds to gain altitude. Better to land with low fuel than crash, after all. Good luck!

I believe mechjeb has that capability.

Once you get to interplanetary ships with huge payloads, building/refueling a rocket in orbit becomes pretty much the best way to go about it. Good luck!

My tugs are quite simple: a central fuel tank with docking ports on the front and back, surrounded by several radial nukes. The payload ship can be mounted on the front docking port nicely, and as many fuel tanks as I need can be docked to the back of the ship, to be undocked when expended. This design has technically unlimited delta-v, as you can dock as many fuel tanks as you please.

I believe Romfarer's Lazor mod adds lasers that can be mounted on ships and rovers. One of these lasers can destroy objects by overheating them. Maybe you could make a laser rover?

Oh yeah, Scott Manley's tutorials are the best. Here's a good all around one: It covers orbiting, as well as a few other things. It is from an older version, but still good.

Great! If you want it, here's the thread where I got my information. It's helped me make many great planes. http://forum.kerbalspaceprogram.com/threads/29896-How-to-Make-a-Perfect-Space-Plane

Here are some of the things that can be on your navball. http://wiki.kerbalspaceprogram.com/wiki/Navball#Gallery There are two green markers on your navball: prograde and retrograde. -Prograde is the direction your ship is heading. -Retrograde is the opposite of prograde- it's where your ship is coming from. In the tutorial you start out in orbit. This means your prograde marker is pointing down the orbital path. If you watch it over time, it actually does move- just slowly, as orbits take a long time. Once you understand how the navball works you're halfway to being a space pilot- it's one of the fundamental tools of KSP spaceflight. Good luck! Btw, if you post some pictures of your rocket we can help you a bit more.

Note, though: only those three will eventually respawn. Any other kerbal you lose you lose for good.

In general, yes. You can move wings backward, add mass to the front, etc.

It is harder than the vanilla game, but it is possible. Are you using the Kerbal X? Here's a good, basic method for getting into orbit that should work for a good ship. http://wiki.kerbalspaceprogram.com/wiki/Tutorial:_How_to_Get_into_Orbit

I'm not totally familiar with the b9 parts, but in planes the CoM tends to move backwards as fuel is depleted. When the CoM is behind the CoL, the plane will tend to flip and be hard to control. If a plane stalls and falls, the CoM will fall underneath the CoL. If the CoM is in the back of your plane, it will fall tail-first and be nearly impossible to right.

Can you post some pictures of your rover? A few things might be happening. -The wheels might have broken on landing. Hard enough hits can do that. -On the upper-right corner of the screen, click the button that says "Resources" to check your electricity just to be sure

Rovers often have trouble accelerating on low gravity worlds. If they hit even a tiny bump they can be launched an inch or two off the ground, causing the wheels to spin freely and not accelerate the rover.

To add to what Kimberly said, it is easier to break that circle up into parts and use multiple launches to bring it to orbit. Docking is a bit of a challenge, but the launch vehicles are much easier to make and fly.

Do you have any pictures of the two docking ports?

It looks like the docking ports are different sizes. Clamp-o-tron Jr's can only dock with other clamp-o-tron jr's. Seniors can only dock with seniors, too. The medium docking port, like the one on your right vehicle, can dock with itself and its shielded version, which is the same size. Edit: looks like two better answers have appeared! Stick with them.

What exactly is your question?
