IMO it takes a special breed of individual to be an instructor and they are few in numbers. I learned to fly on gliders with an instructor who also happened to be a full scale glider pilot. Most if not all instructors in our hobby are not what the title implies and relay nothing to their students. My advice is to watch how others fly and those approaching the emulation of full scale flight are the ones you seek out for instruction. If helicopters are your choice be warned there are no instructors and your on your own.
