1) The biggest myth with hovering is you need a big prop, this is usually said by people who like to talk theory and actually can't hover.
2) Next myth buster is gyros help,,,, to many people trying to jump the basics and in the long run it takes much longer because you never actually 'learned' the basics.
3) Many think hovering is just hanging there as motionless as possible, but hovering is torque rolling, dirty hover, slow flat spin, funnel hover, stationary knife edge,stationary rolling harrier (when windy), slow torque roll circle (i only know one person whom can do this
)) ) and of course the endless entries and exits to a hover.
