Re: ESC prob...
Can you describe the sequence of events better ? Was the motor running fine at any point ? How long did it run ? Was it run without any load ? Have you tried changing components (battery, motor etc) ?
Smell is also a very good give away for hardware problems !

Re: ESC prob...
Also, check for any dry solder joints... Mystery ESC have good reputation. As suggested, do post the complete sequence so that others can help better.

Re: ESC prob...
The same thing happened with me. Please change your motor. Test the motor with different ESC and you Mystery ESC with a different motor.
In these cases there is usually a short in the Motor. The three wires going into the motor should not be short till they enter the coil.
What i did was, i pluged the ESC into the programming card and checked from there that the ESC was working or not. Then I just kind of changed certain settings to just give it a reset.

Re: ESC prob...
Even if you connect ESC to Rx without motor it should work (with built in BEC). Normally BEC shuts down with a low capacity battery. Use recommended LiPo for a 80 Amps ESC.

Re: ESC prob...
In this case you should charge Rx with auxiliary power. I don’t have much knowledge with ESC without built in BEC, and let other senior member’s advice.
I think 80 Amps ESC is overpowered for a 18 Amps motor.

if you are able to connect the esc directly to rx then the esc should have a BEC. i once had similar problem, but later found out that i had connected the esc to rx terminal in wrong polarity.

Re: ESC prob...
if your esc dont have bec it will not power up, then u need to power the rx with a battery or a bec, if motor not power with battery connected to rx u can try to change the end points on the throttle channel in case the programming of endpoints is wrong,
what radio are u using?
have u checked the throttle curv?

Re: ESC prob...
try connecting like this.
1.) Do not install any prop on the motor.
2.) Connect all the 3 wires of the motor (which you have tested on another ESC and is working fine) to the ESC to be tested.
3.) Connect the ESC to the receiver at channel 3.
4.) Turn on your Tx.
5.) Put throttle to MAX on Tx.
6.) Connect the battery pack to the ESC (check if your receiver is getting power now)
7.) If receiver turns on (on some rx there is a small LED which lights up), then your ESC has BEC.
8.) leave tx throttle at max for 3 seconds and then turn it to MIN.
9.) Check for any music from the motor (it is the motor that makes the sound, and not the ESC) (If no music/sound, goto step 12)
10.) This should calibrate your trottle on ESC.
11.) Increase throttle on tx to see if the motor is working.
12.) If there is no sound after connecting the battery pack, then the ESC is not working. there is a problem with ESC.

Re: ESC prob...
Are you sure there is no soldering problem? And if the ESC did not have a BEC you need an auxulary power source for the RX. Did you do this earlier while testing the motor?

Re: ESC prob...
Hai guys.. The esc doesnot have a internal bec so i use an external one... I connect my esc to throttle pins of the rx and bec to battery pins.. I connented the motor to esc, turned on the tx then connented the battery to esc... the bec is connected to the input terminal of the esc so bec also turns on thus rx turns on... No music from motor... No responce from esc.. tried with other motor/lipo combinations still not working..
removed the cover of esc, removed the heat sink but no sign of any burns or no smell... tried to get the esc into programming mode by turning on the rx while the throttle stick is all the way up, still no responce...
please advice...
