  We study the grand unification model flipped $SU(5)$ with additional
vector-like particle multiplets, or ${\cal F}$-$SU(5)$ for short, in the
framework of General No-Scale Supergravity. In our analysis we allow the
supersymmetry (SUSY) breaking soft terms to be generically non-zero, thereby
extending the phenomenologically viable parameter space beyond the highly
constrained one-parameter version of ${\cal F}$-$SU(5)$. In this initial
inquiry, the mSUGRA/CMSSM SUSY breaking terms are implemented. We find this
easing away from the vanishing SUSY breaking terms enables a more broad mass
range of vector-like particles, dubbed flippons, including flippons less than 1
TeV that could presently be observed at the LHC2, as well as a lighter gluino
mass and SUSY spectrum overall. This presents heightened odds that the General
No-Scale ${\cal F}$-$SU(5)$ viable parameter space can be probed at the LHC2.
The phenomenology comprises both bino and higgsino dark matter, including a
Higgs funnel region. Particle states emerging from the SUSY cascade decays are
presented to experimentally distinguish amongst the diverse phenomenological
regions.
