SAS modules produce a better torque distribution off center of the rocket. I.e. Just below a tricoupler or on top of radially coupled boosters. Don\'t use shock plates as landing gear if you are new! They bounce and snap back because of... things. Wheels or RCS are the way to go. Got a problem with breaking your rocket? Use the struts! If you plan to use many of C7\'s mini fel tanks, the disclaimer mentions the unstackability of the tanks, but this problem can be overcome with 3 struts!
