John is right. You won't have any trouble FLYING a cub. They are a piece of cake.

But taking off with your first taildragger is always an interesting experience.

Get used to taxiing while holding full up elevator to keep the tail on the ground. When your ready for take off, keep holding full up while you add power. Once it starts rolling, slowly let off the elevator (Enough to let the tail come up, but not so much that the plane noses over). At the same time, it will want to pull to the left, so a little right rudder will be needed to keep it straight, but be careful not to over-correct. Just keep your rudder inputs gentle. It takes a few take offs to get used to it, but you'll get the hang of it in no time.
