SLS help

[F3ARSTUNTS]

Ok, so, I've built myself a rocket to go to the moon in RO/RSS using the SLS mod with a launch system. Its having trouble lifting off (not because of low TWR) but its kinda tipping but the center of mass and thrust are at the middle and its being really sensitive and very hard to control because of that (it also kinda gets out of wack if im using Mechjeb 2). I can link both the mod and my craft file for some experienced SLS user or RO/RSS players to have a look at. I'm a new player to RO/RSS so thats probably why. It would be VERY appreciated if you could tell me why its having trouble.

Have you skimmed the mod's thread for any potential bugs others are having?  If not, I may give it a look.

What SLS Block are you trying to fly?  I assume the Block II.  If so, what boosters are you using?
