Soyuz tipping over

[skkayula]

Good afternoon lads,

I've been trying to launch a Soyuz made from the RSS mod for days now, but I fail.
The launch works fine until I drop the boosters. As soon as they are empty, I jettison them, MechJeb starts to yaw at its maximum and the rocket flips over.

What am I doing wrong?

I hope somebody still reads this forum and has a reply for me...

Thanks!

Moved to mod discussions.   
 

Sounds like you have a command pod pointing the wrong way.

Is the center of pressure (lift) moving forward of the center of mass when you do this?  Try looking at it in the VAB with the boosters off and the core at partial load.
