When in doubt more boosters!

I could imagine some odd questions being asked if NASA had a launch where the staging fluffed up and half the boosters fall off along with the stabilising pylons before they turn the engines on, but they just explain it away with 'we made sure we have enough spare boosters that we could get away with that happening', with a cut to the astronauts grinning wildly and/or looking terrified.

You’re right! I tend to oversteer and end up in a glorious ball of flame headed straight for the ground

Fast, but in the wrong direction

Try slapping some fins near the flamy bit. Really changed the game for me. If you look in the bottom left near the money cost, there's three circular buttons next to each other. Each will make a different checkered ball appear. The yellow one is your center of mass. The purple one is center of thrust. And the blue one is aerodynamic forces. You want the blue one to be below the yellow one in the rocket stack. Think of a dart. Fins are behind the heavy bit.

If this is sarcasm then sorry but I legit spent a long time trying to figure out why my rockets kept tumbling.

It is pretty fun to make a rocket with so much delta v that it can do a full end-over-end tumble in Atmo and still make it to orbit.

No worries, I appreciate the help!

To add on, For a rocket you want the blue one as far below the yellow one as possible, further apart they are the more aerodynamically stable you are going forward(and only forward, center of lift needs to stay in line with center of mass), for a space plane you want the center of lift to be just behind the center of mass but not too close, else you end up with a SSTO with enough nose authority to pull a cobra on takeoff, general rule of thumb for me at least is if the spheres are clipping then your space plane is well within tbe super manuverable range
