seems i've ran into an issue that makes far unusable for me currently, for some un-explained reason if i use a lf engine my rocket(even with fins) decides to flip out in flight though if i use a srb everythings fine. if you know of any incompatabilities heres my mod list

This is not an issue. This is expected behavior for unstable rockets. Adding fins does not guarantee that rockets will be stable; body lift created by the nose can be extremely strong. I have no idea what changes to the aerodynamics and mass distribution are created by using an SRB in place of a liquid engine and tank in this particular case, but it is a possible outcome.

Closing as there is no bug or incorrect behavior to fix.
