That sounds important in a PA18* and similar but with this small little beast, stick back is just important to keep elevator from shaking. Rudder is pretty effective and CG is low. No, that vid was made because I got constant talks about "isn't it more difficult? ... more complex? ...but a nose wheel is far more ..." - that stuff.
