The binding energies of neutron rich strangeness $S=-1$ hypernuclei are estimated in the chiral soliton approach using the bound state rigid oscillator version of the SU(3) quantization model. Additional binding of strange hypernuclei in comparison with nonstrange neutron rich nuclei of same atomic number takes place at not large values of atomic numbers, $A=B\leq\sim 10$. This effect becomes stronger with increasing isospin of nuclides, and for "nuclear variant" of the model with rescaled Skyrme constant $e$. The binding effect becomes somewhat weaker with increasing atomic number at fixed isospin. Hypernuclei (Lambda)H-7, (Lambda)He-8, (Lambda)He-9 are predicted to be bound stronger in comparison with their nonstrange analogues H-7, He-8, He-9; hypernuclei (Lambda)Li-10, (Lambda)Li-11, (Lambda)Be-12, (Lambda)Be-13, etc. are bound stronger in the nuclear variant of the model.
