Hellcat wing-flap question (0/1)

Sometime ago I made a 3D model of a Hellcat and made
animations with it.
Of one detail I am until this moment still unsure and that is
the mechanisme of the wingflaps.
In all the reference material I collected I can't find any real
detailed information.
I included a picture where the wingflap is in a outward position.
The hinges don't look very strong on this but I am sure in reality
they are.
That's why I would like to ask if someone has more detailed pictures
of the mechanisme. Thanks in advance.

I included some stills of the animations.
