I have just deleted fairing and my rocket was stable again. Thx for tip about Center of Mass, i will test it:D

So, i made a rocket(medium sizes), putted SAS and lots of RSC(that thing with monopropellant), but at 2-3k meters its top begins to spin, after which it simply breaks off. On the top of the rocket i placed big, big repeater from mod DMagic Orbital Science. How can i stabilize it? P.S.:I will upload screenshot soon.

Thank you all guys for help, especially @4x4cheesecake for his save file. From now on i'll be carefully with building rockets:D

Sorry for my english. So, i have launched spacecraft on the Mun's pole,collected lots of data, but ran out of fuel. Its on high orbit of Kerbin. I've launched satellite to save this ship, but i can't do it myself. Manned spacecraft named as "Восход-2". Save this ship and point to to orbit with Pericenter under 70 km, then save the game, please.
