A tilted tower? Please can you produce a sketch?
About TRPT my concern is the low potential of scaling of flying rigid torque transfer elements (weight, momentum effect…), excepted in the very difficult configuration of multi stacked rotors.
The only one fully soft TRPT, without any rigid flying torque transfer elements between the flying and the ground rotors, is Rotating Reel System. But it does not work very well.
I see a possibility to scale a lot by removing any rigid flying torque transfer element. Certainly the proportional height (tether length / rotor diameter) is low, but it is not a problem with a huge rotor. There remains the problem of the torque transfer ring, perhaps to be transformed into an additional wind turbine.
