The plane is rather heavy and trimmed rather stable. They say c/g something like 7.5'' behind LE what means 20% static margin - overly stable. You'd have to ''hold'' the plane with up elevator till it reaches high flight speed what is no problem if the model is overpowered at the same time. That's what model fliers are used to, unfortunately. All the good advice, for instance yours, comes from full-scale pilots. They are not necessarily better pilots but sometimes they have learned to know their reflexes and to overcome them if they are wrong. The up-elevator reflex, the pick-up-with-aileron reflex, the forget-rudder reflex, all mentioned by you, are clearly seen in the video. Stop it at a certain moment and view it full-screen and you'll see all these reflexes in one single picture.
