If you mean two of the 3 wires from the ESC to the motor then yes,this will reverse the motor.Whatever you do,do not reverse the red and the black wires from the battery to the ESC or this will burn it out.
they will still have to swing in the direction they were designed for.You can use them just like the normal props but the motor wires will require to be swaped .I am using them on my foamy 3d with no issues i just adjusted the motor rotation direction accordingly.Please rewaed if you found my answere useful. Thanks.
They do match, I just tried them on my Quadrocopter. But those are not GWS Props and the quality is not as good as the GWS. Can only be used with Propsafers. But thgey do fly. I will use them for flying in my garden, es I do kill to many EPP-Props at the trees :) and those are really cheap.
