I just got a new Walkera 4 3b with brushless motor and aluminium upgrades,
First everything went on smothly but now i am unable to start the motor. It first stotters and then both motors die until I reposition the throttle to zero and then move it upwards again.
Have you experienced something similar? What dou you think? Is the Receiver broken?
At first disconnect ESC and replace with any servo that channel, where was connected ESC,if servo will work,problem is with ESC.If not -receiver.Hope it helps.
