P-shell A = 7 hypernuclei are considered in the cluster {sub {lambda}}{sup 5}He + N + N model. The folding procedure are applied to construct the {sub {lambda}}{sup 5}He - N interaction. We use the OBE simulating NSC97f potential for {lambda}N interaction and various phenomenological potentials for {alpha}{lambda} interaction. Configuration space Faddeev calculations are performed for hyperon binding energy of the {sub {lambda}}{sup 7}He((1/2){sup +}) and {sub {lambda}}{sup 7}Li((1/2){sup +} and (3/2){sup +}, T=0) nuclei. Predicted value for B{sub {lambda}}({sub {lambda}}{sup 7}He) is 5.35 MeV. This value is obtained when the {sub {lambda}}{sup 6}He(2{sup -}) excitation energy is equal 0.26 MeV by the adjustment of pair {sub {lambda}}{sup 5}He - N effective potential to reproduce the experimental value of the {sub {lambda}}{sup 7}Li((3/2){sup +}) excitation energy. Our results are compared with those of E. Hiyama et al. Phys. Rev. C 53, 2075-2085 (1996)
