Make sure the wire connection at the board wasn't bad. I have had the strands in those small wires break and do exactly what your motor was doing. That motor may be fine. Strip the ends a little bit, tin up and try it one more time.
Albert, you are a hero in my book, I retract anything I've ever said negative. Your clear precise right to the point advise is priceless. If we ever meet the drinks are on me.
Yet another timeless video! I have a Diatone Intrepid with less than 10 full packs ran thru it. 1408 4000kv Mamba mtr. Bummer!... Great tips on this vid... Thanks Albert!
Thank you VERY MUCH for this video. One of my quads motors was acting similar. I performed the test you showed, and got the same result, so I replaced the motor, and bam, up and running. This is my first quad and I had ordered one extra motor but had no other parts. I ordered the Tinyhawk Freestyle 2, and had done no "tiny" soldering. With the limited tools and knowledge I have (being new to the hobby), this video was EXACTLY what I needed. Really really, thank you.
Albert, another test I do, is to make sure there is continuity between the 3 cables on the motor, they are attached at he end, and a lot of times is one of the cables that breaks, and most of the time is fixable. When the cable breaks and is missing one of the motor facets they behave like you showed at the beginning of the video.
I had the same thing happen with Armattan Oomph and Racestar and at the same time HGLRC Flame and the Tyro79 motors were fine through much worse abuse. Since Eachine usually makes shit so my uneducatedguess is they did quality check by mistake. Someone at the motor factory was so tired that he leaned on that big red lever, the one that says "do not push" and that turned on the quality control machine. That day yield dropped down to 5% and I was lucky to get the surviving motors.
it will fly i have flown with different size motors the esc compensates for the difference but still very informative they say the drone only flys as good as its worst motor will allow Thanks Albert
I have a Love/hate relationship with 4in1 ESCs because of that very problem. I have at least 5 that only function as 3in1s. Last time I tested by swapping, I burned the test motor. At least I used an old 1806. In my case, it's always the ESC.
Thanks for posting.What would I use for a search term in youtube to decipher startup tones from motors? I bought a cinewhoop type BNF quad that everything seems to check out right in betaflite but when battery is plugged in the tones are like nothing I've heard before.I know not much info to work with,but I'd just like to know where to start looking for an answer
Try measuring the resistance and capacitance of each winding as compared to a good motor windings. So let’s say phase 1,2,3 measure between 1-2, 2-3, 1-3. Ohms and Henry’s that may show which winding is off. Just thinking out loud
Yes it will definitely fly, all motors I believe it will not spin faster than your lowest kv motor, no reason not to fly it. I have mismatched motors on some of my quads. You can attach a drill to the motor shaft, and measure output from all combinations of wires, 1 will be drastically different. Thanks A.K.
Papadoc Fpv yep I can vogue for this too. I have also tested motor windings with the drill constant speed for voltage differences between each winding lead. Also ohms test numbers I believe would tell for an issue too.
Those are great questions, I'd like to know the answer also. I'm having the same problem with my GT-R90, I keep frying a motor, wondering if I can mix motor brands, same size and kv?
Why does it always seem to be left rear motor (3??) failing on these all in one boards...I love my Emax Tinyhawks but I’ve had three develop the same issue...Emax was cool and after sending them some vids...and confirming that two TH were only a few months old...sent me out two new AIO FC/ESC boards...within two weeks one of the new boards developed same issue?? I’m careful to disarm etc after crashes...pulled the motors they seem to work fine...swapped plugged in motors...board seemed fine...(intermittent e-problems...like a British sports car 😜) ....walked thru possible mishandling by me with their techs (great service btw) ....hell the new board didn’t even touch the grass much...any discussion on others experiences would be enlightening....
I made the same test and it was a burnt motor and not an esc. I bought another motor and installed it in the previews esc then I open throttle and burnt another motor. It looks that fc cannot handle 4 motors only 3.Why is that?
Yeah it'll fly the kv is close enough they are far enough apart it may be hard to tune, depending on the gram force lift. The flight controller handles the balance of the gram force on each motor so it'll speed it up or slow it down accordingly. I ordered the wrong kv of the same motor 3 were 1507 2800kv the one was 1507 4100kv and the pull of that motor was so more more it had one corner jump up for like .2 seconds then flew decent. but 3-3600kv and 1-4100kv didn't even phase the flying characteristics.
Hi Albert, would you happen to know if the FIMI A3 lens fogging issue ever got fully resolved..... or is Banggood still selling FIMI A3s with that same issue? Thanks, Ken.
Just in case you didn't know, the prongs of the multimeter have caps which can be taken off so you have a longer contact to work with, felt like an idiot when I learned it myself having used it with those tiny contacts for so long.
Hey man I have a newish drone never crashed. I waterproofed the board (nazgul 5v2) that was working fine for a day after & I landed in rocks & a rock was stuck in one motor I flew for abit and landed and after I got home the drone don’t make the dee dee noise after the battery is plugged in.. what do you think I need to replace the esc or Fc?
If you don't get the first three beeps, the ESCs are dead. If you get the first three beeps but not the last two, the FC is either dead or the connection from the FC to the ESC is broken.
@@AlbertKimTV okay I think it’s the FC that’s dead.. if I get a new one and plug in my dead one and save files & load onto the new one it will be good?
Hi mate. I have this quad, and after a very slightly abrupt landing, and this same thing happened. Not even flew one whole lipo. Are these 4 in 1 boards very delicate? I had a mantis85 and the same thing happened. Please help because its putting me off the hobby, and parts are being discontinued. Cheers
These smaller parts can break easily sometimes if you crash them just right. Sometimes some people are just really unlucky while others are surprisingly lucky. There's no foolproof way to know.
I'm having a simular problem. I crashed my novice 3 and bent a prop shaft and replaced the motor. I tested it in betaflight with props off with no stutter but when i put props on and connect the battery and then arm it i get stutter. When I apply throttle slowly it takes off (uncontrollably) and i have to disarm it to stop it. During bf testing once i got *runaway* flashed on the goggle screen. Can you or anyone that see's this help me figure this out?
I would love to know what might be the problem with a motor acting like that and looks fine and not burnt up. I think the tyro would fly fine (a bit glitchy unless anti-gravity is way up)
My cinerace is doing the same thing I just got it yesterday and when I was setting up it pushed itself and go caught on some plastic now the motor spins but real slow and then it’ll shut off and beep I’m guessing there’s a short in the motor
I have a drone with this same problem, but when the motor is cold it spin very well but suddenly it gets hot and then spin in the way tahr yours were spinning
@@AlbertKimTV okey, the fc started to smoke when i but the fc into the esc and got fried, when i did this the camera and reciver was still pluged to the fc, do you think motor,camera and reciver also got fried?
@@AlbertKimTV well now I'm thinking its because I dont have any motors wired up yet usually I have motors installed before checking too see if everything working
Rip it she'll be fine. Mismatch individual escs can even work for beaters. To test motors spin shaft with drill and measure that voltage is generated about the same between each lead. Finally compare with known good.
Hi Albert. I have two doing this now. I switched motor out and it seemed to do well for a few trips then BAM the motor 4 was back to twitching. I’m lost. Now I don’t know if it means the new motor is bad or what. The struggle is real.
Is it common to have a motor start working again after recalibrating in BetaFlight and then stop when small resistance from crash ... Guessing it's the motor

@@christopherlee3045 wow
Yes i believe will fly and be fine. I had a 2” micro that I flew w one mismatched higher kv motor for a long time and it did not seem to affect it.

@@dstaron3162 always take the component out of the circuit to test no mater what it is.
So why when the back left motor is bad are you testing the back right motor???

Is it always the same motor? If so, there might be a flaw in the motor that is eventually killing the same ESC.
Pretty nice, Albert! Great job! 😊
Is it going to fly? Sure. Should you? I don't think so. 😬
Gday Albert, if the kv is higher on 1 motor the quad wouldnt fly evenly it would spin up faster and crash as it did, awsome Albert great job mate.👍🛸
Hi Albert! I know it will fly...but, I can’t tell you whether you should (other than for demonstration purposes).
I made the same test and it was a burnt motor and not an esc. I bought another motor and installed it in the previews esc then I open throttle and burnt another motor. It looks that fc cannot handle 4 motors only 3.Why is that?

What does "runaway" mean on the OSD? i havent seen that one before.

Seems like a defective ESC. The runaway flashing on the screen could also mean the props are on wrong or the motor is spinning the wrong way.
Great video Albert Thanks

So did the esc turned hot when the first motor were plugged ?
no... see the follow up video
I would love to know what might be the problem with a motor acting like that and looks fine and not burnt up. I think the tyro would fly fine (a bit glitchy unless anti-gravity is way up)
Probably the winding is broken somewhere not easily seen.

I have a drone with this same problem, but when the motor is cold it spin very well but suddenly it gets hot and then spin in the way tahr yours were spinning
probably a motor problem with an almost broken winding.
after a snow crash when i plugg in the battery nothing happends. how do i know witch part is broken?
Any lights? You may have a bad flight controller. I would need more information to diagnose. Not enough info here to really tell what is going on.
@@AlbertKimTV okey, the fc started to smoke when i but the fc into the esc and got fried, when i did this the camera and reciver was still pluged to the fc, do you think motor,camera and reciver also got fried?
my esc wont make tone when startup, when i plug the flight controller up it works with battery power but i dont hear a tone
So you don't hear ANY ESC tones?

The ESC has an issue and is killing the motor.
Nice flying at the and Albert lol!!!
Great Channel!!
👍😀👍
A motor that has a short has drag solder 2 leads together you'll see it doesn't spin as free
Very helpful
thank you, Albert 👍👍❤️🙏
Yes it will fly. It will actually fly pretty good. You'd never even know that it had one motor with different kv. I've done it b4 when in a pinch. Lol
yes it will fly the FC will work that out
Is it common to have a motor start working again after recalibrating in BetaFlight and then stop when small resistance from crash ... Guessing it's the motor
You just had a dying ESC that gave out after the crash.
@@AlbertKimTV it would sometimes come back after recalibrating.
Nice education video. Bookmarked. (Y)
It will fly with different kv motors but will feel wonky
it's an Eachine
yes its fine i have one with 2 1104 and 2 1105 and it flies great lol
Yes ist will fly. Perhaps you will notice some lack of power, because the new motor have less kv
Of course you should send it ;) I bet it flies just fine, well as good as can be expected from a tyro
Yes, please fly this drone with the mismatched motors. I have a feeling that it will fly just fine.
It will fly @nickburns done an eclair build where he had 2 7500 kv and 2 10000kv motors
nice thats how i test . yes it will fly and no u shouldnt but u can .i would throttle limit to 80%
SINCE U TOKE %20 KV AWAY
With lower kv the motor will spin SLOWER, so there is no need for a throttle limit
yes it will fly -- all of the motors will spin at the lowest spinning motor.
Fly it, it will fly but motor 4 will max out while the others doesn't
It will fly fine, I promise
Just send it
my motor is doing the exact same thing. time for a new motor.
Yes send
Will .... IT.... Fly.....?? ..... Send IT!!!!
This is lit.
Let er rip!! Bet you have better crafted quads to test though... lol!!
Yes yes
i got the saME PROBLEM
o yes definitely fly.. no problem wit tat.. 😁
Too bad I can't sauter... no flying for me
Fly that thing thanks
Send it!!!
My guess is Yes it will fly. But will it fly as intended? No...8)
It should fly. But being eachine nothing is a sure thing. 🤓
#sendit!! sorry, I
had too
