Cubs need the use of rudder more than many other models and pulling to the left with a conventional engine is to be expected. Start the take off run with the elevator holding the tail down, don't snap the throttle open but feed it in progressively and counteract the swing with rudder, ensuring that if there's a crosswind that the wings are kept level with aileron. As the speed rises, let the tail come up (it's a long way to level on a Cub!) and let the model fly off when its ready. Dragging it into the air too soon risks a stall and control authority will be very much reduced even if it keeps flying.

Watch any full size and you won't see it clawing for the sky (airshow stunters excepted) - there will be a period while it accelerates to a safe climbing speed parallel to the ground. Try to duplicate that and I suspect you'll find it much easier.
