I have 6 planes that are tail daggers. We have a paved runway and a grass strip next to it when I am making friends with a new plane I start in the grass the extra drag on the tail wheel helps to keep the tail behind the wings. I have used two methods 1 the GLH method taxi to a starting spot jam the throttle and go like a bat. 2. Ease the throttle hold some elevator work the rudder till it gains enough speed to be effective let the tail come up and gain more speed and fly ever so gently up and out.
