Okay, i'm relatively new to KSP and this is my first mission to Duna so it might be massively overkill. i'm trying to send a rover to duna on this mission.
The rover i'm trying to get off the ground is ever so slightly imbalanced and the rovercore is upside down. just after i launch the rocket, it enters a roll i can't counteract with ''E'' or ''Q''.
I've tried a dummy payload of the same weight as the rover. the payload consisted of just some fuel tanks to see if the imbalance is the problem. in this same launch i set a probe core in the proper position so it isn't upside down anymore. however, it turned out none of this is the problem because the same spinning happened. also, i believe there is a part clipping bug that might cause this spinning but i also eliminated that problem with the earlier mentioned test run. (although i don't think there are any bugged parts on the rover)
Here are some pictures of the craft: https://imgur.com/a/iJDYHcf
The gimbal is disabled on the booster vector engines, so only the core has gimbal.
i really don't know anymore so i would like to ask you for help or potential solutions.
