wired ESC to motors the wrong way

Hello, today I tried to lift my completed quad into the air in my room. Well, when it got 5 cm off the ground, prop nuts came loose and 4 props and 4 nuts flew in all directions, one even hit the TV:( seems no damage though.. Basically my motors spin the wrong direction compared to nuts tightening direction. The CW spinning motor's (which was marked CW on label) nut also tightens CW, which is wrong, as I now know.. So, what is the best approach to remedy the situation? I could resolder everything and swap motors. Or would reversing the motor direction by programming ESCs be a better option? Every guide shows that the X type quad should have motors spinning CW-CCW-CCW-CW if we look from left top to right bottom. Would it be ok if I swapped directions and the motors would be CCW-CW-CW-CCW? Ok for FC calibration software? Or maybe I should try to put some locking nuts? Any recommendations? Are they reliable? I am using CC3D with some Blheli 12A ESCs. Thanks for any info.
 
OK, so front-left and rear-right are CW, front-right and rear-left are CCW. And yes, I always use nyloc nuts. If you need to reverse motors, you can change any 2 wires. But that's the great thing about BLHeli ESCs, you can reverse the motors in BLHeliSuite
 
So you think I can just use nyloc nuts and it will have enough strength to withstand the unwinding force? I know how to reverse, but then it will be front-left and rear-right CCW and, for example, when running calibration in CC3D software, it presumes that your quad has front-left and rear-right CW. It is probably configurable, just haven't had the time to look it up, so just wanted confirmation that CC3D software will still be useful to me if I swap rotation directions. As I understand Blheli ESCs are reversible through flight controller software only if they have specific firmware version. If not, then I need to solder some connector to ESC directly to allow it to connect to PC..? And this is the only way to check what firmware version ESCs have also?

I think he's inferring the motors are spinning in the proper direction it's just the prop adapters that are wrong.

@eek

Some motors have removable swappable prop adapters that bolt to the top like this.

Unless yours are like that you'll have move and re-solder.
 
Easy peezy. 3 options, nylocs, swap adapters, swap motors. Or a forth,
use some blue threadlock & hope for the best. go with the nylocs for ease. Or change adapters for peace of mind & safety.
