Tail draggers are way easier than those darn trainers. Ever since I got into tail draggers, take offs have been much easier. I hold full up while I'm taxiing. Then right when I raise the throttle, I go to center on elevator and wait for the tail to rise. Just touch of up, and off it goes. I admit that sometimes I forget to let off the full up elevator...but I realize it and let off. Maybe you had full elevator and hit a bump? We have some nasty bumps at our field. A few times they sent me airborn before I was ready. It happens.
