I've been flying a long time and one of the hardest things to do is take a plane off slowly IMHO. Because you are always behind the plane. Meaning that you are reacting to what the plane is doing and what the ground is causing the plane to do. You want to stay in front of the plane meaning you want to fly the plane and not react to the plane. I know to a newbie this is not a easy thing to do. But this is what you should be trying to do. If you give enough throttle within a few feet the tail will be flying then you are in control and the plane is reacting to you and not the ground. Tail draggers are a lot of fun. But remember that when the tail comes off the ground YOU are flying the plane not the other way around. I hope this makes sense to you it, has worked for my students. Practice, practice, practice then practice some more.

Let us know how things go.
