a nice job, I spent close to 40 years giving flight instruction, are you working from a teaching plan or script or are you winging it as you progress? You may want to produce a short video on the four fundamentals. This would provide much needed background information to the user and fill in some of the gaps. Your videos as developed are more or less a do as I do, with the user not having an understanding of the relationship between airspeed and control input. The result of which is they may or may not have the same result as you and with no clear understanding as to why?
