Multiple flexible assemblys

Hi,

In my project I needed to add 5 gear motor flexible assemblys in my main assembly. The gear motors are available for viewing and i can give you the files if requested.

My question is, do I need 5 diferent gear motor assemblys because each engine moves independently therefore the gears will have diferent positions or i just need to copy them to wherever I want?

Because every time I copy the motor and create the mechanical mate in the new one the entire project returns yollow errors.

I'm using SW 2013 SP3

What should i do?
