Wet spaghetti rockets

Recommended Posts

Properly designed and controlled rockets don't wobble, even without mods.

Don't blame the tool...

I've been playing KSP for quite some time now, and have built several different rockets that have allowed me to visit every moon and planet in the game, so have a fairly good idea how to put a rocket together. I'm just saying that I've never experienced wobbles as bad as I did on a fairly simple rocket I put together just to visit Mun. It consists mostly of 3.5m parts, which I thought would have made for a sturdier rocket. Most of the flex seemed to be centred around the connection between the transfer stage and the capsule/lander, but it was also evident at the decoupler between the 2nd stage and the insertion stage. Or at least that was true of the original design, which wasn't that far removed from my final solution, a pic of which is included just below my original post. I finally got it to a point where it was manageable, but was disappointed at how many struts I had to use to achieve that.

Someone above has said that Squad likes wobbly rockets, as it encourages people to design better rockets. Personally I feel they are forcing us to build rockets with inferior parts. The KJR mod has shown that it's possible for the joints to be connected in a way that doesn't lead to flex and impossible to control rockets, and surely that has got to be better in the long run for the longevity of the game.

KJR shows that it is possible for a computer to simulate poorly designed rockets into flying well. Flex is vanilla representation of something gone wrong.

I also built a quick 3.75 m rocket intended to carry a 3-kerbal command pod to the Mun and back. I used 4 struts (between two 3.75 m stages, because the upper stage had a 2.5 m engine), and the rocket reached orbit on the first attempt without any wobble.

One particular problem with 3.75 m rockets is that the Mammoth is too powerful for small serially staged rockets such as yours. You'll experience a lot of wobble, unless you tweak the thrust down.

I bet i can make your rocket not wobble, without KJR or excessive struts.

Have you tried reducing reaction wheel torque and gimbal range?
