What 'stress', chopjock? And how does it create a greater likelihood of engine/tail rotor failure?

Using 'all that power'? SND and crab@ have both explained that it is a maximum of hover Tq plus10/15%. It is actually a relatively gentle application and very controlled, with little stress compared to many SE departures of 'pull max take off torque, nose forward and rotate'.

I've done a reasonable amount of both. I'm the guy that crab@ refers to as an ex-mil driver who would reef in power to get up quickly, and had to re-learn to be a bit more considerate to follow the correct profile.
