But if you can do it, do it This way may damage the FET. OR The other way! The next step has the video of me removing and replacing the fet with a soldering iron!.
Follow the video! Just tape it up or put some heatshrink! Oh and don't forget to replace the heatsink!
After soldering please check for shorts in the circuit. Especially the large power handling type like you are working with here.

I actually repaired my hubsan X4 this way. One day I decided to pull it apart to see what is inside, and I noticed the microphone area was unpopulated.
The sound quality from it's recordings was really quiet, and the fact that it was probably just picking up pure electrical noise would explain that!
I went ahead and installed the smallest mic I had, and after tring to find a place to fit it, and trial and error, I finally gave up on it.
When I went to use it, however, I did not notice that I had made a tiny solder bridge form across one of the motors. Unknowingly, when I put it all back together and tried to fly, I killed the motor output, I noticed at first when I armed it and revved up the throttle, that it would black-out and not fly, as if it was a completly dead or really weak battery.
Then I smelled really faint, almost unnoticeable magic smoke and the thing game back to life and flipped out!
I noticed that motor no longer worked! After pulling it apart again, I noticed what had happened, and the TINY fets, the ones in pain-on-the-butt SOT, that one of them was ever so slightly charred.
It was barely visible, and it took awhile for me to confirm that under a telescope eyepiece lens.
I stuck the iron on it and got it off, and soldered some really thin magnet wires to the 3 pins, and connected it to a really simple LED circuit to test and confirm it was indeed an N channel FET.
I then replaced the charred one on the hubsan X4 flight controller with that new shiny one. And got a chance to do some SMB work on tiny stuff for the first time: You sure learn skills quick when franticly trying to fix crap LOL!
Now it almost works flawlessly! Well almost, that one blade would now always twitch when powered on. Turns out I accidentally removed a small resistor close to the base, and there was no way I was going to get that resistor back on where is belongs, it was just far too small: practically microscopic, easily mistaken once off the board, glued to the iron, as a for a bit of dirt!
Nor did it even have any value or number printed on it! So for uniformity, I did that same thing to all 4 resistors next to their respective motor driver FETs.
Now all the blades twitch on power up, so it seems normal. My guess is that it occurs when the microprocessor inside is booting up, and tests all the outputs to make sure they initialized and work, not sure though!
Trying to draw a carbon track across the pads with a pencil did not help much. Reply 3 years ago. I did eventually end up replacing the whole control board on that micro quad, as I later fried the 3V LDO regulator on it too!
I tried to fix this by using an LED as a shunt regulator, but that failed. Also, to make it so all the motors twitch and to verify the missing resistor on the replaced FET was the cause, I removed all of those resistors.
Turns out the purpose of those resistors was to prevent spurious voltages building up on the MOSFET gates before the microcontroller enables those pins as outputs.
I think this is because when it enters this panic state, the micro disables the output pins, and rely's on the pulldown resistors to keep the MOSFETs off.
You at least got to learn something from that quadcopter and sure did I! Truly amazing! A couple of years back, I remember trying to add another channel on one of the chinese radios.

The gate will be discharged through your finger and the meter reading should go high, indicating a non-conductive device. I Made It! Designed by Trece.
