I have a 3 advanced and the front rt. blade threads on backwards than what it says it should! This is my second one in two weeks that did this, took the first one back but maybe its normal?
Two of the props thread on one way and two the other - they should match up with the black and silver colored hubs. If it's anything different, there is either a run of bad props...or, a run of improper motors!
Check the link below for a video I did a little while back on props for the P3 and the different options available. -
