Those are the normal quick release the new ones just came out a few weeks ago. I recommend if you have the money replace your props now with the new ones. Way better and secure much better.I believe my props are the quick release version 2.0… Inspire was purchased about three months ago… There is a white dot on the prop as well as the motor to indicate which props go where. Came stock with the inspire. We are up at around 80 flights. Thanks again for any feedback.
