Good question bugdevheli. And agree stronly with you NickLappos. When looking back on my training I had 2 very good instructors but one that was very experienced in alot of aspects of the helicopter industry and another with fewer hours but mainly all instructing (hour building) I found the more experienced instructor would always let you get yourself deeper into a situation before coming onto the controls if it was needed which I found to be alot more beneficial and motivating during my training. Or his inputs were very little that you would hardly notice the effect of his movements. Getting yourself out of a situation gives you a feeling of really learning to fly the machine.
Where as the other instructor was more of a nervous pilot in a way and would be felt on the controls more often which would sometimes get frustrating when you knew you could of resureccted the situation. Maybe just an experience thing.
But anyway that's my input. At the end of your training though it is really only a licence to learn there is so much out there we don't know. Just have to be willing to take on others opinions and experience.
Happy new year for all ahead.
