Thanks for the precision @Ollie.
Please do you think if it would be the same (ratio of lifter kite area / rotors area) as only the pull is used (in yo-yo mode), and not the torque.
I am experimenting (0.555 m diameter, and sweeping 0.24 m²) rotor(s) of gyrokite below a tiny lifter kite (a 0.2 m² parafoil). For now the angle of elevation of the kite alone is about 45 degrees; a rotor (alone, without body, rotating around the tether via a small hollow axis) below said kite has 35 degrees elevation angle (as for the complete gyrokite, the body providing low drag).
My question is: if I add several (even numerous) rotors below the same lifter kite (0.2 m²) their elevation angle will be the same (35 degrees) or not? I guess the reply is likely not but I am not quite sure. Thanks.
