Turnigy squeaking sound

Message Topic Search Topic Options Post Reply Create New Topic Printable Version

Hi, i've got this sound with the turnigy 2205/1500kv, Plush 10 and gws 8x4. first i thought with 3s and this prop it's too much amps for the esc, but motor is rated for 8amp max and 8x4 is recommended prop size. what does the out of sync mean? bad esc quality? could shortening the leads from esc to motor help? different timing also changes the power, right? since i don't have an amp meter i'd have to trust the overload protection of the plush 10, but for some reason i just don't . I know I should get an amp meter...

	I now have TURNIGY 50-65C 320kv Outrunner (Eq: 4130/16) , TURNIGY Plush 80A w/ UBEC Speed Controller and Hobbyking SS Series 60-70A ESC. I have to set the timing to high when I use the Turnigy speed controller so it no got out of synk, but when I use the Hobbyking SS it go ok on low timing.

	There is one possibility here to. Sometimes the bearing will spin in the race under load and cause a squealing sound. I had that happen with a couple of smaller motors. Check the bearings in the motor.
