  A minimal fermion-scalar preonic model containing two fermionic and one
scalar preons is proposed. This scheme allows to prevent the occurrence of
undesired SM-level particles, namely leptons and quarks with unusual electric
charges. Similar to the previous FS models, color-octet leptons and
color-sextet quarks, which are expected to have masses much lower than the
compositeness scale, are predicted. Observation of these particles could
provide first indications of preonic models. FCC (SppC) pp option will give
opportunity to probe $m_{q_{6}}$ up to 48 (75) TeV and $m_{l_{8}}$ up to 15
(27) TeV within one year operation at nominal luminosity. FCC/SppC based ep and
$\mu$p colliders will essentially enlarge covered mass region, namely,
$m_{e_{8}}$ up to 23/27 TeV and $m_{\mu_{8}}$ up to 68/80 TeV.
