This is one of my early flights with this Hobbyking Stearman. For me this is new territory because of the model's size and especially its weight. My hat cam leaves a lot to be desired and I am sorry. My affinity for "scale" models is satisfied to the extreme with this beautiful model. The model is dragging it's behind not because of balance issues, but my fear of the use of enough throttle through most of the flight...My fault, not the models. It comes with plenty of pep.
