Use the controls to the fullest. It is not LTE if you don't use the pedal all the way, it is "shy pilot". I have tested helos for 30 years, and hit every stop on every control at one time or another. You must use your machine, not ride in it, if you expect to earn your pay.
greenthumb, you have few facts, and many assumptions here. Without knowing what torque he pulled, and his Nr, you do not know what he did to the machine (he might not either!). OGE, with a sling load literally calls for over pitching as a possible cause. Was the 6th time at higher OAT? Where are the facts, not just the broad circumstances?
