The first run of V3's had the connectors on them and the wires in the box. After that they have had the power wires soldered on. So there could be both out there. The sure way to tell a V2 from a V3 is by the case and the color of the control board. The V3 case has more space between the fan and the top of the case and more space between the bottom of the controller and the bottom of the case. The control board on V1 and V2 is green. The control board on the V3 is blue. If its in the hobby shop and the box is marked V3.......then its a V3.
