One gear for each fin as seen in the image and one gear perpendicular to all 4. So when the horizontal gear rotates, all four gears of the fins rotate making the fins move. However, my prototype doesn't seem to be working as i imagined it would. Is this the right way to fabricate this system? Does anyone have any other ideas on how i can do this better?

As you have not told us what your system actually does nor have you posted an image of it then it is hard to help.

My guess is that the motor only drives one of the vane gears

The drawing is useless to understand the behavior.

The motor is supposed to make all the fins rotate at the same time

I was conscious of that when I wrote Reply #2.

You have still provided no information about your attempt to implement the idea.

Based on this description, the fins on opposite sides will rotate in opposite directions. Is this what your design is supposed to do?

quick edit: Look at an egg beater in your kitchen. The beaters turn in the same direction because the driving gears are on opposite sides of the main driving gear.

OOPs !

In opposite directions - one clockwise and one counter-clockwise

Good catch. Must the the weather or something. My wife would tell me I need to use an eggbeater more often.
