Here are some things you can do to protect the motors from the sand:
Take off from a large landing pad
Hand release/catch your drone so it does not have to touch the ground
Take off from an area that is damp, so the sand will not kick up into the air
Take off from a nearby street and then fly over the beach
Basic drone flight guidelines in the United States
Fly at or below 400 feet above the ground
Always fly within line-of-sight, if you can’t see it, bring it in
Stay away from airports
Stay away from airplanes - they have the right of way in the air
Do not fly over people
Do not fly over or close to sports events or stadiums
Do not fly near emergency situations such as car crashes or building fires
Do not fly under the influence
Be aware of controlled airspace - use the B4UFly app
Your drone will need a Remote ID broadcast transmitter

Si el motor de mini 2 gira pero algo pegado esto lo solucionará y que liquido usaste?gracias
@@nelsongallo5645 Es exactamente lo que tenemos yo y otras personas, usamos alcohol desnaturalizado. Cuando arregles tu dron, infórmanos.
I just followed this tutorial, worked perfectly, didn’t take arm or motor off just dunked them in brake cleaner,ran drone for 10 mins. All told took me about 5 mins to do . Excellent tip, I was just about to order a new motor when I saw this ,so thanks for sharing .
You are very welcome. Enjoy your drone, if you like to do so, I encourage please donate any amount to support channel▶
Awesome fix for the specified problem. Took my mini 2 to Mexico for fun in the surf and sand and the things never been the same since. The left rear motor seized up almost completely, only turning with much effort. I tried this but I didnt have to dunk the motor completely. I instead only removed the props and motor mounting bolts to expose the underside of the broken motor. Holding the drone up so alcohol doesnt enter the arm, I squirted alcohol into the motor and spun it by hand until the motor spun freely. If it doesnt do it at first, keep spinning and adding alcohol. Yeah man, you got it. Good stuff Mr. Original Poster.
Enjoy your drone bro!!
I crashed mine into a palm tree and it flew again fine for 10 min. then the rear motor developed a very hard stop in either direction. I appreciate the input on this OPs vid.
Grain of sand stuck a motor and caused my drone to backflip into the dirt, freezing up all 4 motors with grit. Could only find methylated spirits out here in the centre of the Australian desert but after a while it did the trick for all 4 and now we’re up and filming again. Thanks heaps!
What an experience.
I'm very glad, there us no other way to get sand out. If you wish we are welcome support
I want to thank you for posting this video. I had a crash landing on a beach and sand got into the rear motors. Those rear motors wouldn’t work afterwards. I didn’t know what to do until I found your video. I followed your directions and fixed the problem myself. Probably saving me hundreds of dollars in repairs. I took the drone out for a few tests flights and everything is working fine. Thanks again.
You are very welcome
Your support of channel is highly appreciated.
Thanks for the hint. I just did a quick visit to my local electronics shop and got a bottle of pressurised isopropyl alcohol and another one of compressed air, almost finished both on the motor and it spins like butter now. Thank GoAsFarAs YouCanSee
You are very welcome. Please enjoy your drone! If you wish to support please subscribe to my channel, and share one or two videos from it, that you think it worth to watch. It help a lot!
Thank you for the informative video, which I used to clean my drone, which crashed by my carelessness, when I hit a big tree and fell on the beach into the sand and on the coral. Thank God not into the sea. I have cleaned it as per your instructions, it is flying normally with no problem. Greetings from the Dominican Republic...
Dominican republic! Nice to jelp you!.
If you want support our channel, support buttons is right by the video. Cheers
Wow! I’m so happy this worked! Was kind of bummed b/c I didn’t want to spend potentially hundreds on repairs. I knew it was just probably something stuck inside, but I really didnt know it was this easy!
Cost $5 and 30 mins of my time. Amazing. Thanks!
Thank you for your support channel bit.ly/ThankMePayPalLink
I very happy that you fixed your lovely drone. Enjoy.
And yes, you are totally right, the space between ROTOR and COIL in this motor is extremely small, and dust turn in to the thick clay, and there is no way to get that out of there, I guess I invented this method, since I did not find fix online.
The bearings in the motor are not sealed - i would be adding a drop of bearing oil to them after washing with alcohol. The shields in these bearings are just basic dust shields.
You would kill drone several times before bearing wears. Also it is operating fine so far.
Thanks for advice
Please explain me if you add some lubricant and then clean with Alcohol?
😊
Thanks a lot! This really helped us. We are just on our 3rd day of the DJI Mini 3 Pro and unfortunately crashed onto "earth ground". It saves us a visit to a service center.
We made sure to really make it dry by spinning (without propellers) for a long period at interval with a mild hot blower also. 70% alcohol works. Let's see if it will work tomorrow after an overnight being stressed thinking what we should do as there was no local service center in our area.
Let us know please. So like share and donate, it help sharing energy
Thank you so much for this fix! I thought I had to send my mini2 back to DJI for repairs but your video fixed the issue for me! I had a stiff rear motor and this fix worked perfectly! Thanks again 😊
You're welcome! That what I explained many these who don't belive it work - distance between motor sraud and rotor less then any send particles so it melting it in to a power that plug and prevent spinning, I've if you have send, first blow vacuum, then mulch it by hand spinning, then wash it. ThT was my original process.
If you feel comfortable you can donate in top message link pinned, or in description.

Thanks for the video! Some sand got into one of the motors of my DJI Mini 2 at the beach. Really thought I'd have to go for replacement but your solution worked really well. I used 99% Isopropyl Alc for it and did this 3 times by emptying the container as it got muddy. Got smooth motion back in the motor and have tested a flight. So far so good!
Sweet! 🙌🏻
Up in description you can use link to support my channel.
I wish your droon long work time.
Use foldable landing, hope it won't fall anymore in send. But if so, you know the drill.
I tried high pressure air , even taking it apart, but THIS is the only thing that worked. Thank you so much. I really didn't want to send it back to DJI and now thanks to you I don't have to and can use it on my trip next week! Sounds loony - but it works!!! I would suggest use 90% or higher alcohol - it dries faster. Also, no need to take the arm off, I just turned the arm down, put it in the alcohol and started the take off. First time it sprayed everywhere so be prepared to cover it quickly if you didn't.
You are right with arm off is easy to submerge properly.
I glad it help your drone!!!

As an RC car and truck enthusiast as well as a Remote Pilot there is another way.
Similar to this remove all propellers activate the drone and start up the motors. Using a good cup of water with a drop of dish soap 🧼 insert each motor into the water and spin till clean.
After you clean out all the motors and whip dry. Finally use a can of electric ⚡️ connector spray and this will remove any access water inside and will quickly dry out the motor of any access moisture left inside avoiding any possible rust.
If you can use a drop of silicone oil to keep the joints where the points top and bottom to keep it lightly lubricanted.
Seems like a lot, but it’s pretty simple. You will not hurt your motors at all using water in this process. The water will remove very quickly any access dirt from your electric motor and get it clean 🧼 fast. good luck! 😊
As an 51 year Soviet Engineer, i would reply this:
Theory is different than a practice.
In theories we can say anything that could work.
Processes you just stated, not only hurt your dron, as water is component that could shorts your circuit.
I would upload your video of doing this.
Next segment is soup, it is not necessary component, as we not washing somethings greasy, water could make components rust, and cherry on your pie is lubricant of silicone you won't be able to lubricate anything, as all tide parts are sealed, and lubrication will capture more dust, and then you will need to use my method to wash crease, as it will be much harder, and messy.
And- we waiting link for your videos please. I hape peoples will avoid this method- i won't deep my 1200 dron deep in tho the water. The best solutions is use guidelines, proper landing places to avoid these processes
It works! Thank you, you saved my day! 😊

Very smart way to clean a motor 👍
my motor literally did this two nights ago and i was scratching my head for a fix. i used air duster and held drone upside down while spraying the air in short bursts into the motor and the debree also came out. this seems like it might work better but now i know twow ays to fix the issue now lol. thanks for the insight

До чего же я люблю просторы интернета.Ваш метод просто находка.Начнём с того,что,загуглил тему-ремонт заклинившего мотора мавик мини 2.Итак,первое- замена луча,второе-просто замена мотора.Уже начал гуглить ,где купить запасной мотор,но случайно наткнулся на ваше видео.Итак,моя история.После пяти полётов,падение в сухую кошеную траву.После этого приходится каждый раз перед взлётом пальцами раскручивать левый задний мотор,надоело,да и ссыкотно так запускать его в полёт.Ваше видео вдохновило меня на разборку этого мотора,Может у меня и не совсем ваша причина,но вы убрали все страхи перед предстоящим ремонтом.Спасибо,что есть такие как вы,по сути альтруисты в любой сфере.
Благодарен за пост. Напишите, чем закончилась история починки. И да вы правы, запускать дрон с клинящим мотором, даже слегка цепляющимся за что-то, для дрона полет может оказаться последним.
@@goasfarasyoucansee Как уже говорил ранее, у дрона налётов мало.При начале эксплуатации внимания на то,что двигатели вращаются от руки с разными усилиями внимания не обращал.Падение в сухостой было по теплу,а следующий полёт был уже зимой и причину заклинивания свалил на падение и грязь внутри.Но после разбора дв-ля ничего не обнаружил,всё блестит,зазоры свободные.Заметил,что лопасти на дв-лях передних лучей вообще свободно крутятся,правый задний чуть чуть потуже,но приемлемо,а вот левый задний ещё туже.Представьте подшибник,закрытого типа с туго набитой смазкой и подшибник открытого типа промытый от старой смазки.,какой будет легче вращаться.Но смазка нужна,поэтому извините,но я не стал использовать промывку в том варианте,который вы предлагаете,лично я за избирательность.Я больше склоняюсь к мысли,что легкое заклинивание,именно в моём случае,связано с браком сборки подшибникового узла двигателя,а именно перекоса подшибника и направляющей втулки(а при отрицательных температурах ещё и просадка металла).Разбирать я конечно его не буду,думаю летом тепло сделает своё дело,а потом посмотрим.
@@denscorpio4666 лопасти на двух двигателях должны туго идти. Сними лопасти и в спирту погоняй моторы, все выйдет.
@@goasfarasyoucansee Говоря о лопастях,я имел ввиду верхнюю обойму-корпус с неодимовыми магнитами.Насчёт промывки в спирту.Работал в электроцехе рядом с обмотчиками,там всегда при ремонте дв-лей снимали подшибники и уже после промывки в солярке проверяли целостность сепаратора и шарики в подшибнике на предмет износа(сколы и т.д.),потом ставили либо новые либо старые после ревизии,естественно туго набивая между крышками новую смазку.Дв-лю без смазки никак нельзя,особенно высокооборотистым.Подшибники коптера тоже являются упорными шарикоподшибниками закрытого типа с туго набитой смазкой.Промывать спиртом в движке коптера нужно всё,за исключением подшибника,но только в случае сильного залипания слоя пыли и наличия ржавчины на полюсах статора и поэтому я за избирательную промывку.Промывка в вашем варианте может привести к гипер мобильности вращения корпуса,что и происходит,потому что очищается ни только зазор между корпусом и статором от всего ненужного, но и вытекает смазка из подшибника.Так как подшибник(обычный шарикоподшибник)при высоких оборотах испытывает большую нагрузку,то без смазки никак нельзя(смазка там специальная и обладает очень низкой текучестью,может даже пластическая),т.к. сила трения сухих шариков приведёт к износу сепаратора,перегреву и сколу сегмента шариков.Ваш метод работает при ржавчине и забитости зазора,но поаккуратнее пожалуйста с подшибником дв-ля,т.к. обычный шарикоподшибник итак очень плохо держит высокие обороты,а мы ещё лишаем его плотной смазки.
@@denscorpio4666 К счастью дрон собирался не русском цеху, не мучайте себя и дрон, а почитайте лучше о чём люди пишут, которым помогло.
Тебе сколько лет? Просто интересно?
Thanks a lot @goasfaras you can see!! My drone is up n running now🙌🏻🙏🏽
Thanks for the video man. But I expected better, did this to see if the grainy feel would go, but sadly its still there, I can still feel the small particles inside the motor when I rotate it with my fingers 😢 the good thing is that its working with no errors so yeah ❤ at least I can fly again
Awesome, little tip, what i show in my video, is to spinn, and grind metals to powder, so you can washed it out.
Sand have metal, and these extremely small, and they get stack inside.
Flight safe, in worst cas you can run it again, just to be sure, for 10-15 seconds, if not.
Then enjoy.

THANK YOU!!! YOU ARE A GENIUS
You're welcome! It was totally my idea based on my own tech experience. No worry about lubrication, aircraft will die earlier before baring seals and greases get destroyed. Also very important in this process, the send must be grinded between rotor and coils 😈
Hi thank you for the video! I have another question, what we have to put into motor after we wash with alcohol? Oils or something?
Sorry for the late response. Nothing alcohol won't wash grease from your bearings as it is sealed with seal. Just don't overdose washing
Thanks for sharing! It worked! 👍🏼
Great to hear!
Hi i watched the video.. What do you think about the bearings inside the engine and the lubricant that is used for the bearings? When you run the motor in a can filled with alcohol, the brown colour you get might be the oil that you just have washed away. Do you think that bearings are fine with none or less oil in a long term use?
I was wondering about this too. But from what read on the DJI forums the bearings are sealed.
@@patrickhdsn You are totally correct these type of equipment's build with high grade materials, including bearings. If you also try grease from open bearing and try to use alcohol, you will find that it will take forever to dilute it.

@@goasfarasyoucansee 💯 as long as you don't use anything too strong or that's not safe for plastics it shouldn't be a problem.
Oil is pink. Sometimes I clean the motor housing by moistening the cloth with 99% isopropyl alcohol due to the excessive humidity in my place. Something pink got on the cloth while I was cleaning it. But I know the bearings are sealed. Most likely, the pink oil smeared on the cloth was left outside the bearing during lubrication.
Hola, está excelente tu vídeo. Yo tengo un MINI2 y Tengo unas dudas , los motores llevan algun lubricante después de la limpieza? He visto en videos que le ponen WD40, o limpiador de contactos, o aceite sintético para motor de auto, o aceite 3en1 para máquinas de coser, no se que pensar. Alguna opinión o alguna marca o tipo de aceite? De antemano Gracias.

Thank you bro it worked!I tried to turn on the motor but it prompt error because the motors were really stucked.So I tried to ratate them manually under the alcohol and it worked!
First of it it turn in to the dust. Second of all it washed out.
Awesome thank you so much It worked!
Thanks for your comment.
I glad it did.

Just crashed my Mavic Air 2 an hour ago, didn't know what to do
I haven't tried it yet but this will be my first time trying to "repair" it by myself
I just need to dip the motor into alcohol and let it spin until it's smooth right? Looking forward for your reply. Thx
Yes.
Prepair it all, as preparation procedures take lot more then a cleaning.
Watch video few times, and you will see, that, taking all blades off, loosing damaged arm, so you can rotate, and place in alcohol properly, so spinning won’t spread all the alcohol all over, you will feel when it spin free.
Before spining, you can rotate by hands first, to mulch large pieces in to powder.
Let me know, how it goes.
I have, larger Mavic as well Air 2, luckily, clearing smaller, and large is never crashed.
Nice thank you, great video and instructions.
Can I ask though if what would you suggest be done if the particles that get stuck in the motors are somewhat magnetic and stick to in stator magnets? And what if some particles get stuck on thr gimbal head?
Thank you God bless
Particles in the sand are obviously contain metal, as we are on earth, it is metal planet. So the sand when it crash between rotor, and stator it create dust, the sand dust is flight out, but magnet dust is attract to rotor, that why we use alcohol, as particles very small and they just wash out. As far as Gamble head, this is good question, there is hiding motors, I would use air dust blower from Office depot or home Depot, see if it will help, I would defiantly not touch head much, as it s very sensitively adjusted.
Let me know if you fixed it, it kind 7 month past
@@goasfarasyoucansee appreciate it, thank you God bless
You ROCK dude!!
🥰🙃
my question is, does that cleaning solution wash the lubricating grease out of the bearing?
Does not. Bearing usually sealed, and grease and alcohol is not easy to mix, grab plate and dry to diluted thick grease and alcohol.

I had a whine in my Mavic Mini on takeoff, and the controller reported "Prop too fast". Before trying this method, I removed the props and blew the motor out with compressed air, and it worked, so I suggest trying that first as the simplest method.
Thanks for sharing. I try mini powerful vacuum, as well air blow, the finest staff is impossible to clean, you will have 1 piece of sand stack in air out from somewhere where was stock, and your drone is gone. ,
I have some small metal particles inside, which are hanging on the magnets.
Is it possible to remove the motor bell from. The mini 3 pro ?
Yes it is possible.
As far as metal particles, they are everywhere in sand.
Sand is the minerals contained metal mixed in most sand, we are on earth, this is metal planet. This method should help you.

@@goasfarasyoucansee thank you.
I mean to remove the bell from the motor, not the blades.
What sort of screwdrivers did you use?
Small hex bit, not remember size
if i put a motor of xiaomi fimi x_se 2020 in wather it will stil working ?
Yes it will.
Remember this is not water, it is alcohol, but you can put in water as long it is not salted water.
Awesome😊
Good idea. But I'd suggest manually starting the motors with the sticks instead of auto take-off so it won't be so messy, and you still have the option of throttling up alittle if you feel like you need the motor to spin faster. And 90% iso alcohol is better for electronics.
Excellent suggestions, Please subscribe and share the video.
Would it be much better if I use 99.9% iso alcohol? I can't seem to find a 90%
Wonderfully solutions. Thanks ❤
Thank you for posting this! I fly my drone in a marine environment, so I suspected corrosion or sand. I used Boeshield T-9 instead of alcohol and it worked. Hopefully, this will keep it working for a while. 🤞
Excellent solution!
I sadly had a crash with my Mini SE and it went into the sand, I kinda started to clean it, so then when I tried taking it off again to see if everything was ok my right front motor wasn't spinning, I got a little scared so I started spinning the motor left and right, which kind of started to free the sand out a little bit, and I kept doing it until the motor was completely free of the sand, I am not sure if this affected the coil or the magnets, can someone confirm this to me please?
Edit: I also forgot to add that the drone started to fly a little weird, it was not stable at all, It flew either to the right side or left side without me doing anything to it (This was when I tested it back home, windless conditions to make sure 100% that it is fine, which right now it is clearly not)
You drone is acting weirdly because of the sand is crashed to dust, but dust is the one that stops spin well.
You needed to clean with alcohol
GoAsFarAs! iteresting .🤝
Used for 3 hours. Work like a charm.
Thanks a lot. Now i know how to clean motors after using my drone in sandy and dusty enviroment.
@@januszblamowski1651 You are welcome 😊
How to do this for front motors?
Same. You just need to detached it.look for bolts for arm
I will try this and let you know the result
Dunking a motor in liquid? Seems like a great idea to me until your 2 miles out and you lose your drone. Never heard of compressed air?
Lots of smarties! At least my drone is still flying and if you tense up and read the comments, you might lose the desire to write nonsense.
And yes, ask your favorite siri about compressed air, I'am no Wikipedia 😉🤟🏻
Works great…. I did it manual and I use 95% alcohol… thanks men 1 of my engines was 100% stuck
You are welcome

You mean saved?
@@goasfarasyoucansee Yes LOL! Hi work as a Wedding and Real Estate Photographer and Filmmaker and I was filming today on the beach and a little of sand got into a motor and you can imagine the situation, thanks so much brother!!!
I wonder if you could just have used any sensor cleaning spray? It probably would have flushed everything out
Uou cant spray. You need to run. Sensor cleaning is evaporate extremely fast if you crack the can- and it is explosive hazardous
DO NOT USE acetone instead of alcohol!!! There is a plastic structure inside the motor that holds the magnets. Acetone dissolves plastic easily.
CORRECT! DO NOT USE ACETONE, AND TECHNICAL ALCHOHOL IT CONTAIN BIT OF ACETONE
Sir if possible you can use contact cleaner for cleaning the motor. Instead alcohol.
Very rarely is alcohol cleaner really 100% pure, but it's available cheaply enough at 99% or higher, usually the remainder is pure water or something equally safe. Contact cleaners tend to leave a lubricating / corrosion inhibiting residue which may or may not be welcome on a connector as it may attract dust & dirt
im afraid to apply any sort of liquid to my drone motors😊, maybe an air duster (pressurized can) will do the job
Your bearings is sealed inside. To washougreas, require you to remove cover of the bearing, take it apart, and spin it in gasoline, or similar liquid like mineral spirits, alcohol won't wash it out, as bearingbis sealed.
It take me recently to washout grease from makita grinder that I restored, alcohol wasn't the best solution to use, it simply did not desove grease, I have to use first wd40, then soap water, then alcohol when crease was out, to remove, and dry water from bearing compone, then I used new grease, again it all was open, in large bearing.
There is no way alcohol even get inside drone bearings over 1 minute. It is impossible technically PERIOD
This is what is bearing look like. Partical of alcohol is so large to penetrate trough seals in the bearing, I would not use acetone, as it can cause damages, not only can penetrate in bearing quickly also can washout liquor off wires, and dissolve plastics.
Unfortunately air won't wash particles that shredded and stack between rotor, and coil

What kind of alcohol did you use?
70% Isopropyl Alcohol Wallmart

Let me know how it is goes.
I fixed mine without taking apart the motor and leg. I used QD ELECTRONIC CONTACT CLEANER (Red bottle spray). First I removed the propellers on the defective motor with the little screw driver, and the I hold the drone upside down with one hand and spray a bunch of QD contact cleaner while rotating the motor with my fingers and used a paper towel to dry the inside of it. It worked so good 👍🏻 Just keep spraying since it gets a good pressure wash from the can. 🧼
Good technic.

I would’ve taken the foam backing off the motor then tried compressed air first. Unless you did. Seems kind of sketchy, tbh.
It help hundreds, air won't blow off sanded dust, plus you do not have to tear a part more.
No more grease on the bearings
Incorrect, using for year now, almost every weekend,
great, after such a wash the engines are not lubricated at all and noboidy know long they will live
If you don’t know how dron motor is assembled, should not say that. Drone motor have no contact lubrication
Drone motors dont have lubricant, they are no contact 😂😂
Thanks man, this video is a life saver, crash my drone in a beach and all the motors are stuck with sand. will definitely try your method
It will take long time, but at least it less expensive. Please subscribe and Share my channel 🙏🏻
Thank God I found your video. I just went to Parangtritis Beach in Java . After calibrating imu on the sand my dji mini2 prop SUDDENLY stuck . A Bit panic but I am sure I will find a solution on youtube. Thank you for sharing diy fix on such problem. I will go home and fix it your way... I hope I can fly again soon.
It will take time. But carefully you can. You might have to grand this by manually run motors. Please help my channel share and subscribe
No relubing of the bearing and bushing, that motor is not going to last very long.
Bearing is sealed and lubed. Try to diluted Alcohol and any greas prior judge. 100th of happy try it, and it work just read the comments. I'm using my more then a year now😄
@@goasfarasyoucansee it's sealed from dirt/sand, not liquids. These cheap motors only have a top bearing, the bottom is a bushing, and nothing sealed about that. The other thing is iron shavings, as you know rubbing a magnet in dirt or sand will pick up iron shavings, your methods will not remove these from the magnets. I have been building, tuning, modifying motors for competition for 4 decades, I know what I am talking about from experience.
Work with gadgets for last 45 years, 35 years ago I was soldering microchips with solder station that powerups from gas burner 😂 Usually there is no metal shavings in this motor, space between rotor and outside magnet that thin that even microns of the sends can't get in between. If few get inside, then they turn in to the powder by crashing between surfaces. There is only one affordable and many time appreciable by hundreds of watchers method is to use liquid, water is no-no, alcohol is perfect, and remember you not spinning. I do not have time, but I more then happy would record video under microscope in that area, to bust thoughts. You have to sit and spin motor for hour in order to wash anything from bearing. Of course there is other methods, this is just a quick that everyone can perform.
Thank you for your thoughts.

@@goasfarasyoucansee your link posted does not work, repost please.
You’ve got sticks down there in this controller - you know? ...
Hi. Can you explain what you mean?
На русском можешь написать что случилось?) такая же фигня
Да. Приземлился на сухой мелкий песок, частицы застряли между ротором и катушкой/обмоткой. Крути пока в порошок несотрется песок, и вымается спиртом
70% isopropyl is 30% water. Perhaps use compressed air?? If the sand is not magnetic it will fall out if you rotate the motor when pointing the opening down, and compressed air can help get it out. If it is magnetic particles then it won't come out so easily and will require further disassembly and removal using something like blue-tac or sticky clay or tape to grab it.
You do not have to use method that helped hundreds of users ))
@@goasfarasyoucansee You said you did not want to use water, just noting out that you did use 30% water. Water may or may not be a problem, but there's a lot of water in 70% iso, and in many cases 70% has other unwanted things mixed in it. For example in 3d printing we avoid 70% iso because these unknown chemicals often cause problems to adhesion. The 92+% iso doesn't have these problems. The motor has a very narrow magnetic gap, and it has a bearing which has some lubrication, and the stator iron may be subject to rust but is passivated against corrosion to some degree. I suspect compressed air and 92+% iso is a safer approach. Others have removed magnetic particles which are very stubborn by disassembly and blue-tac or something sticky that grabs the particles when compressed air fails to dislodge them. I fixed mine without using iso at all. Iso may damage the lubrication so might be a problem in the longer term. Hopefully I won't need to fix them too often by avoiding flying too low, crashing or landing in dirt/sand. I will use only compressed air if possible, any liquids may cause long term problems to the motors.
@@alanb76 And that why I recommend to use what I use, exactly based on what you said.

I think you could’ve save so much time using a small vacuum and a air duster! Just my thoughts.🤫
NO- NO- NO. It won't work, it is nearly same to vacuum from the motor that is size of the matches head) Already try it, and come up with better solution, if you would read comments, it helped hundreds.
Now that you flushed ANY lube out of it's bearings...
