Mod Kerbin Shuttle Orbiter Help!

[KoolBreeze420]

The mod appears to be working fine except the prebuilt's For example craft titled KSO Block 10.craft will easily make orbit once reaching orbit the craft spins out of control I tried adding more RCS ports tried adding weight inside the shuttle, even mechjeb in unable to control the craft to circularise orbit around Kerbin.

IsHas anyone else having issues with the KSO mod? Is there another mod I Need to add to get better control, does Jeb need more experience?

I should also mention that I use sandbox mode when installing and testing mods. I was thinking of getting FAR (Ferram Aerospace Research)mod , but I am not sure if it will make things any better.

This is why I came here to ask if anyone can shed some light on this.

Much appreciation for anyone that takes the time in reading and answering.
