Abstract: A minimal fermion-scalar preonic model containing two fermionic preons and one scalar preon is proposed. This scheme allows prevention of 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. The FCC/SppC pp option will give an opportunity to probe $m_{q_{6}}$ up to 48/75 TeV and $m_{l_{8}}$ up to 15/27 TeV within 1 year of operation at nominal luminosity. FCC/SppC based ep and $\mu $p colliders will essentially enlarge the covered mass region, namely $m_{e_{8}}$ up to 23/27 TeV and $m_{\mu _{8}}$ up to 68/80 TeV.
