The four motors works well as soon as the could start. What I mean it's that they are a little bit reluctant to start powered with 4.2v and an XSD7A blheli ESC. With 8.4v it's better they rarely stutter. I will have to change the allowed power at startup with the software blheli suite to fix that with the Xsd7A speed controller. with other ESC like some cheap 6A board that I own no problem at startup. the price was very attractive and I don't regret this purchase. To change the rotation direction you just have to inverted two wires in the plug like it said in a comment here, or when you solder directly the wires, on the ESC board. You can also eventually do that with software if your speed controller support this feature. The motors are very light and the power consumption is quite low as soon as you use it with small propellers.
