I'm not sure how much it shows? But even with tail dragging Models (High Wing) for sure.Right rudder is needed on take-off.I know this from experiense.With a Model I have flown! It could be caused by the pitch of the prop wanting to push the nose to the left?Meaning a steeper pitch should make you need more right rudder on take-off?

Yup, you got it. When the prop is moving forward with a pitch up or pitch down on the airplane, there is an effect that makes it yaw the plane one side or the other. It's called p-effect and the steeper the pitch up or down the more it wants to yaw, and the more rudder you need to keep it from yawing.

Right on.
