Does it matter if all four propeller threads thread in the same direction on a quad copter, Do they have to thread in the same as the Phantom motors? I bought some E-Max Motors they say is an upgrade for the DJI Phantom! All four propeller threads are all threading in clockwise! Shouldn't two of them have the nut go on counter clock wise so they don't come off with rotation of motor? Please anyone that has changed out motors that may know the answer let me know. I'd like to install them if there is no issue with them being like that..
