Hi everybody i'm a new user just ordered a vision2+. Been reading a lot and watching youtube so slowly gaining knowledge but my question is... How do i get more of those plastic pieces called gimbal collars in the rc drone video where they show you how to remove your cam before flight. I'm planning on taking the camera on and off quite frequently. I found some for 5 bucks at dronefly but they cost 32 bucks shipping and you only get 4. Is there something else i could use or shipped for less to canada thanks!!
