      Thank you for the info, drawing also helpfull but Z-helix is not using turn outs to connect the inner and outer cycles. If you take a look at the link:
      I have upload a photo and note that particular part of the track which seems to using also a small straight part, probably 8588, i am looking for the rest piece

      If such a part is available for 195mm curve with 220mm curve instead of 195mm i can go a little bigger or as i said how about using a part of flexi track and do what i like? Do you think flexible track can do the connection? I think i must go and buy some tracks and experiment.
