Hi guys, I broke this part of my camera (see picture attached) and bought a printed replacement on ebay. How do you stick the "gimbal roll arm ring" to the motor?. Do you use glue? (Now that is broken I cannot see remains of glue from the factory in it.... hmmmm If you use glue, which glue would I have to use and how much?. Any videos about how to do this?. Thanks so much!!
