Looks like two of the motor wires are shorted, I’d say. Check for it with a multimeter.

You need a higher watt soldering iron. Those look bad. Tin the leads first before making the connection to the solder pad.

Also use leaded solder if available. Just don’t eat it.

Thankyou everyone, im sorry for the late reply, turnsout that the esc is faulty either it shorted inside or its over voltaged the motor so that the motor is overheat and sparks very big. Thankyou
