Just building a new quad and motor 4 doesn't spin at all.

Tried 2 usb cable
Tried looking in ESC config.. only 3 ESC show up..
Measured Resistance between motor 4 poles all full continuity

Is the ESC faulty, or what can I do without having to solder off the motors.

make sure none of the wires from the cable between the fc and esc have been pushed out of the connector

also feel the motor when you plug it in to see if it makes the whole start up sound

Ah yeah tried plugging fc/esc cable in and out. Will check the cable individually

#

you are using the speedy bee fc as well?

keen tendon
#

Yeah f4

#

Difficult to see if the pins are bent inside but I assume not

Insulated cable from the cap is touching bottomside of the ESC

just the first part or both?

#

the first 3 beeps mean the esc powered up, the last 2 means its communicating with the fc

the other motors will make that sound

#

you need to hold that motor and feel if it does

keen tendon
#

3 beeps and 2

nocturne sinew
#

nocturne sinew
#
