You'll have to learn to use the rudder to counteract the effects of engine torque.
(As the engine brings the prop up to speed, the effect diminishes due to less torque needed)

The harder you're on the juice, the worse the effect will be.
With practice, you'll be feeding in the rudder automagically

My old Cub used to give me fits, until I learned proper rudder control.
Afterwards, I found it great fun to immediately let the tail fly, and just steer it with rudder.

There are cheats. Some folks install a gyro, instead of learning to use the rudder, for instance.
Do yourself a favor, and practice holding a bit of right rudder... you'll get it.
