I presented a rotor built with tied flexible wings. This method could apply for a FlygenKite rotor. The secondary turbines (4) would benefit from a higher TSR, above all if the used wings have an increasingly higher lift to drag ratio as they approach the tips of the rotor. If a value of 5 or 6 (without secondary rotors) could be achieved, secondary turbines would not be too heavy by using light high density generators.
A sketch below:
