Taking off in the Dora is frustrating until the moment you realize what you are doing wrong.
I had about 30 crashes while I always started carefully with not to much thrust, hoping to get a "feel" of the aircraft. That was wrong: you do not have rudder authority at low RPM. So once I realized that the forward vector was my friend and I needed overwhelming forward power (and propwash) fast, I just slammed the throttle forward and then I finally got rudder response and I could "feel" the aircraft. With the amount of power the engine gives you, you are airborne in no time.
It is immensely rewarding to master the take off in this bird.
And OK, somehow I will figure out how to land the thing ... I hope??? Maybe I should have tried that first :=)
