About the pack by dtobi

The goal was to make the parts to build shuttles by only using this pack, stock parts and maybe other parts like B9 aerodynamic parts.

The engines are can combined with bi-, tri-, and quad-couplers (strut the stronger X3 engine). A NASA shuttle-like appearance can be achieved with the tricoupler.

The two weaker engines allow orbital maneuvers because the shuttle main engines will be useless after dropping the main tank moves the center of mass into the vessel. The OMS drives are useless in atmosphere.

The fuel tanks come in four sizes, allowing various asymmetric shuttle-alike rockets.

Fuel flow breakers balance tank center of mass (CoM) which must carefully: your tank's weight and vertical position, along with your engines' and boosters' power, determine your CoM's alignment with your center of thrust. The engines' large gimballing stabilizes craft.

The main engines fly crooked with the CoM right above them and at full throttle overheat.
