Rocket spinning


Recommended Posts

Moving this over to Gameplay Questions, as Support is more meant for issues that are definitely the result of the game glitching out.

Rockets flipping and spinning out of control is a common problem for new players. We can't really diagnose anything specific without a good look at the rocket, so screenshots would definitely be appreciated; however, you may want to try some of the advice given in this tutorial in the meantime to see if it helps fix any of your problems.

Hope this helps, and welcome to the forums! :)

If you're rocket is rolling (pointing up but twirling)

If its only spinning at the very start of the launch, use launch clamps.

Use radial symmetry mode (default mode in the VAB)

When adding struts, sometimes if you only support one side of a booster stage, it can tilt a little bit and cause spinning.

If all else fails, a sufficient amount of control surfaces or RCS can counteract

If you're rocket is having a hard time pointing up:

Try adding more and larger fins at the bottom of the craft.

Mitigations for flipping/spinning rockets:

1. put fins on the back

2. make the front end more streamlined

3. move the center of mass forward

4. don't go too fast too soon (in particular, stay under Mach 1, i.e. 300 m/s or a bit over, until you're over 10 km). Note: you can adjust the thrust of solid fuel boosters in the VAB if they're overpowered

5. don't make sudden sharp turns (i.e. try to keep your rocket pointed very close to prograde, and do only very gradual gentle turns until you're out of atmosphere

Scott Manly has numerous Kerbal youtube videos out (many of them now outdated), but I really loved his newer "Career Mode Tutorial" series. This guy is intelligent, funny, and interesting. And if you play the video series on one side of your screen, and follow along with KSP running in windowed mode on the other side of your screen, you'll be up to speed pretty quickly. And yes, he covers a lot of the issues you mention and that folks here are trying to help you with. But it's all rather involved, so...

Fly safe!
