We are discussing different cases, The Skycrane, The Spanish Light Twin, and the camera ship the is shown in the video spinning straight down for about 700 feet.
In the case of the Skycrane, I do believe it was not LTE, it was an RPM droop that caused the problem
In the case of the Light Twin, I do believe pulled power waaaaaaaay beyond limits and managed to droop the RPM, as impossible as it may seem due to the fact that he must have been pulling an obscene amount of power, as I have mentioned, the NR RPM in a 206 L model will probably stay close to 100% NR up to 120% Torque if you pull collective reasonably smoothy. It is amazing for me how he continued the takeoff when there was a very obvious RPM loss heard. I have caught the NR trim with my glove and trimmed it down accidentally in flight, just 2%, and I realized how quickly you react to any sound that shows NR drop, in a second I had lowered collective and scanned everything to see what was going on. I have no idea how he elected to continue the takeoff with such an obvious NR droop. Pilot should turn their ears into a NR tachometer and be able to detect any change.
Then in the case of the video of the spinning camera ship, I do believe it was LTE, the engine had enough power to turn the Main and Tail rotors at their designated speeds, and the pilot applied full control inputs to the pedals but the aircraft still turned because the Tail Rotor was insufficiently effective to counter torque under the circumstances.
