If you have mastered the easy sport and learned how to land with some speed I would think you should soon be ready for an Extra. Just try to keep it light to keep the wing loading down as much as you can. I would get help from your instructor the first few flights to be safe. Let him land it so he can help you keep the plane out of a stall. Extras are not hard to fly you just have to remember to keep up the speed. Good Luck!
