Interesting idea

Trying to decode the math...is it 5900 minus 10 for kite?

$1900.00 for the H + $4000.00 for the Tether = $5900.00 to basically have a kite with 6 motors.
OK, now If you go to Walmart with your $5900.00 (that what it would cost you to have a Typhoon H kite) in your pocket. Pick up a kite. Go to the cashier (I'm assuming they still sell them. I haven't bought a kite in 40 years). When the cashier rings it up (I'm guessing $10-$20). Reach into your pocket and remove $10-$20 from the 5900.00 you would spend on the Typhoon H kite and give it to the cashier.
$5900.00 - $10.00 ( or $20) = $5890.00 ( or $5880.00). You walk out of Walmart with your kite and you still have $5980.00 or $5990.00 in your pocket and you have your kite with a Tether attached.....

If you have a contract to justify the expense, and the customer wanted full length videos of for example football practice games to watch players technic and performance, then this could be justified by keeping it in the air for the full game, and not having to land and change batteries. My concern would be heat and stress on the motors, and the rotors, for these extended times.
Just a though.
