STOP. SPINNING.

[Guest]

I launched a probe into space for some research and money, then i just removed stage 3. all the sudden, the probe started spinning. i cant turn SAS on because its a probe. help im freaking out

Time warp.

The starter probe core; the "Stayputnik" doesn't have SAS, you would be better off using Kerbal Pilots for the time being until you unlock a better probe core.

We maybe need more details to be able help. A screenshot is a good start. 

The craft was flying straight before decoupling?  Is this atmospheric flight or space flight? You still have full control of the vessel (control point, electric charge, communication link)?

i was doing space flight and time warp didnt help

In part. Pilot skill,  available technology,  vessel design and mission complexity may be all relevant there.

Good news: it's not an aerodynamic issue. 

 Bad new : can be a lot of things. 

The amount and quality of the  help we can provide is directly proportional to the amount and quality of info you provide about your problem.  So far you provided very little. 

Please a screenshot(so we can see your craft and a few other things) ,  a description of your objectives (where you want to go)  and how are you trying to handle your vessel ( control inputs).

Things like this are often caused by part clipping. But as others have said, we need more information and especially a screenshot.

If you have a joystick installed, be sure it's centered. Check the indicators on the lower left to see if something is telling the ship to rotate. 

 

If those little yellow indicators are not centered, the craft is responding to steering commands of some sort.

Trim settings cause this.  I don't think it would happen on a Stayputnik, but press Alt+X anyway, just to be sure.  Trim settings will also offset the indicators @Vanamonde mentioned.

Both memory and the ksp parts wiki insist that the Stayputnik has no torque (don't all the rest have SAS?).

SAS and torque are not the same thing.  SAS works via either reaction wheel torque or RCS, true, but you can get torque without SAS.

It doesn't have SAS or torque, but you can add a reaction wheel to the craft that will give it torque (but not SAS)  Since he didn't provide a screenshot there is no way of knowing what he has going on.

In spaceflight spinning happens as result of either angle between thrust and prograde (a), or displacement between center of mass and center of thrust(b).

So:
(a) place the engines or part which engines reside on - at angle. Can be very very small angle. Can be angle to prograde vector(which is easy to spot with CoM, CoT balls), can be angle to the center (engines angled sideways, which is hard to spot). A design to help prevent this issue, is to build the needed part on top - and then take it at base, place where needed/w. mirroring, and only then rotate the parts.
(b) engine thrust not on the line with CoM, that one is easy to spot - you got yellow and purple balls.
