Hello i have a EK2-0705b that i bought from deal time i belive it was called, i got it for my lama v3 that a freind flew and when he crashed it smoke poured out of it, i tried new motors and then i bought that 4in1, it was the wrong part and when i looked into returning it they wanted me to send them pictures and other things and i just got lazy and let it set around till finnaly it was to late to return it anyway, so if that part will help ya i will make you a good deal on it.
