Take the fuselage of your cub and look at its side from a distance. Imagine the plane taxiing across the ground. You will imagine the wind, which is parallel to the ground, hitting the elevator lifting it up. This lifting force makes the tailwheel ineffective. Now, couple that with the lack of wind on the rudder, also making it ineffective. You get what you have.
The only solution is to hold up elevator long enough for the rudder to become effective.
I have three cubs, once you master the cub all others are easy.
Watch his elevator. On the takeoff he actually lifts the tail, which I dont do. Even the full scale starts to turn. On the landing he holds full elevator keeping things straight.

Can anyone spot the flaw in the video reference the Cub?
