i swear that as soon as the person connected a motor and and FC and tried to spin the motor, it want up in fire just like all the ESC`s i have "repaired" :D There is more damage than just the FET, there is either some resistor busted or the FET driver as well which need to be checked if needs replacement. Only once i managed to fix an ESC and fly for remainder of the season all other 20 attempts it went up in fire the moment a motor was spun. Beeping fine, spinning NOPE!
Hola. recién compre una ESC SPEEDY BEE 55A, pero resulta que cuando conecto el cable de alimentación y mido continuidad, me pita. Y no hay ningún cable haciendo contacto por ningún lado. Lo mas extraño es.. que sin los cables, vuelvo a medir y me indica que hay un tipo de corto.. La ESC esta completamente nueva... Hice una prueba probando la continuidad en el TVS Diode y me pita.. Pero desconozco del tema.. podrías orientarme
@@TheFruitcake1983 thanks for the tip. Soldered some new condensators on the esc but it didn’t worked. The fc will get the power so i believe it can only be the power circuit for the MCU. Dont know how to fix that :/
@@MJ-mw3ni Did they break on impact? If so, the cracks could be either in the board or in the active components. I have fixed my problem now because the GND leg on the connector burned off or broke off inside the board after a fall.
@@TheFruitcake1983 after a crash i didn’t saw any further damage under the microscope beside 2 broken capacitors. Maybe the pcb go some hits. Do you think there could be some high voltage spikes destroying further components? There also no shorts on the Esc and the resistant is equal to any motor output.
@@Breakingcarbon Okay.. So i was testing my quad indoors and crashed into a pillow on the bed so I immediately disarmed it and then motors started making some weird tone so I got it to my desk and checked everything was ok and then the moment I armed it there was a spark which freaked me out and rest is history.
Hello, i just got my charging port off the board, it is needed to the drone to make the first "OK" sounds? since that i only hear the motors"beep", theres any way to repair it?
@@nazarkokhan mosfets on drone esc's burn out when there is a sudden spike in voltage and or current and those voltages/currents are too high for the mosfet to deal with causing it to get hotter and hotter untill it completely melts itself - these spikes happen when the motors are pushed to their limt during extreme flight manovers , as for your first question , he used the mosfets from the 3rd 4 in 1 esc (the one with no burnt mosfets ) these boards are called doner boards and used its mosfets to replace the burnt ones - hoope this helps

man you are the most patient human in the world
moral of the story... maybe speedybee costs more than rush!

can you send link wich mosfet you used for replace?

bad idea to heat without unsoldering the electrolytic capacitor or at least put a metal shield over it

Do you have the schematics for the replacement?
I have some broken condensators on the back side but dont know what what exact part i need.
solder out one serviceable one and measure its capacitance

@@MJ-mw3ni Anything can happen after shocks, cracked capacitors could have shorted out etc.
One of my Speedybee esc has a faulty MOSFET in the exact same location as yours. Makes me wonder if its some kinda design issue.
A very likely chance, many esc experience the same problem

how did u test the motors? they didnt seem to move or smth
They do a little move while activated
What flux/solder do you recommend?
My recommendation is to use KESTER solder with flux
For flux I didn’t have some recommendation
What is the type of mosfet to order for this repair?
Me too, dont know which mosfet to find exactly key world searching to buy.
I took a similar ESC
Where did you get mosfet for replacement? I also have broken one
And also what was the issue? Why did they broke? Was it factory defect?

😮😮
Bro i have same esc i have some issue voltage sensor is not working or firmware is showing unknown esc I tried to flash but not working flash error
Your version is correct?
Next time try low temp solder. It will keep the solder melt uniform. Good job though. Those ball grid parts can be a bitch.
