Most taildraggers handle pretty good on take off. depending on the Cub , you can have your hands full with ground looping. I taught myself to fly on a Greatplanes Cub .20 . It would chase it`s tail on the ground so bad , I was ready to give up.
Ended up doing nothing but taxing and aborted on ground take offs ,over and over again , till I got it down. Buy the time I got it in the air , found I was using rudder right off the bat to fly the plane .
You would think a Cub would be a easy flying plane, and in most cases it is , but just when you think you have it down , it will bite you. Practice on the ground , will help you a lot ,with rudder control and throttle managment.
