Hmm... is it the sound that an ESC sometimes makes, you know that high pitched sound or is it a mechanical sound?
If the sound is most noticable at low speeds and when just starting I'm inclined to say it is the ESC making a noise.I just listened very carefully to mine and it makes a slight noise when first hitting the throttle-caused by the ESC-normal.
Also there are bushings on each end of the motors that could whine and make a high pitched noise if they are dry, one small drop of high quality oil is good for that.
of course you also say it is stalling and that just isn't right I would try another motor in it and if it continues you may have an ESC problem.
But before you do anything drastic check all wire connections closely and the whole driveline very closely.I really dont like the wires, they feel fragile to me.(probaly just my big ape hands-lol)
ESC=Electronic Speed Control
