this is a smaller aurorazdarcho version without a head. I made a slightly bigger version before because this seemed to be not efficient enough for flight. later I found out the inefficiency of my previous forward-sweep attempt. that is without gullwings lift at upstroke was partly negative. when adding the gull wing , this created also dihedral, and made the pterosaur glide extremely stable. I haven't made a video of a good long glide, but it is possible, in a gull wing configuration a large head crest is not destabilizing. this version is bit difficult to control, because to steer I need to add negative aileron (strongerwingbeat) together with rudder. only one of both doesn't make a change of direction. probably the control system must be improved, make a fuselage for this one and strengthen the inwash of wings a bit (to have allow have more stabilizing by dihedral during flapping).
