Need help with noise from motors

[Kendallst]

I need some help with trouble shooting a possible ESC or motor issue.

Video attached shows my 5" Alien frame with turnigy 1300mah 3s battery.
ESC - Littlebee 20amp
Motor - Cobra 2204 2300kv

Disregard the initial take off, fast forward to about 38 sec in when I'm doing straight line movements.
Sounds like a squealing pig with possible rattle noise. Is this normal for those motors?

FYI - turn your volume down its loud!

Sounds like you need to change the ESC timing.

 

[Kendallst]

Are you referring to calibration?

 

[Jaxx]

No. The throttle calibration is something different. Check out the videos below. They should give you a better understanding of ESC timing. Having the wrong timing can cause the motor to squeal.
