You're fricken awesome Josh. Seriously. Some people have the knowledge, experience, skills, and fundamental understanding that you do, but they're completely incapable of teaching it effectively to others. Some people are great teachers and very articulate in conveying effectively to others what they know, but they don't actually know much that other people want to learn. Some people have all of the above but have little interest or enthusiasm in sharing it. But in the quadcopter, FPV, and Tx/Rx world, you DO have all of that. So rare. And SO appreciated. To be honest, we need a few additional Josh Bardwells...one for RC planes, one for RC helis, and now that I think about it, probably a lot of other topics too. Thanks for all you do man.

[@TheRealMichaelAndretti]

ferrous dust is the WORST!!! I can't tell you how many times I've had to dissemble and clean motors just like this! Toothbrush, alcohol, compressed air, blue tac, q-tips... yup use them all!!! If you can get enough PSI out of a compressor, sometimes you can blow through the top of the bell, while slowly rotating the motor back and forth.. sadly it only works about 1/2 the time and motor disassembly is required! For those that were requesting bearing replacement, I suggest looking up "Project Blue Falcon" (RIP miss ya JC) he has many excellent videos!!! Cheers and #sendit

[@ignisnatus3839]

if you have a bit of thermal paste laying around, place a dab in the screw head. it wont get in the way of the tool, and will easily squish out when you place the tool into the screw.

[@BlueDroneBlues]

Hi Josh. I have been into RC cars 🚙 and trucks 🛻 for years. When I get dirt into my electric motors and had to clean them I learned different ways to do this. Brushless motors I’d remove and disassemble and easily whip them clean with just simple water 💦. Dry them out with air or a dry cloth than spray them down with electric motor cleaner which helped remove a lot of access dirt. Finally use a clean cloth use a couple drops of silicone oil on the steel rods to keep them lubed and reassemble the motor. Brushed motors (or where disassembling isn’t an option like DJI drones): remove the props place each motor into some water 💦 with a drop of dish soap 🧼. Shake the motor in the water if motor doesn’t want to free spin due to sand and this will generally remove access problem pebbles. To really get the dirt out turn the motor on in the water and run it. The water will wash out all the dirt. Dry the motor with air or a cloth than spray down with electric ⚡️ motor cleaner or an electric ⚡️ connector spray that will remove the iron particles from the motor. Whip clean and use a Q-tip with a couple drops of silicone oil on the ends to help keep lubricanted. I never had an issue doing this, no rust and my motors work like new afterwords. ❤

[@RIDG_DIGITAL]

Late to the party here.. Thanks for the info. Super helpful because I've got some mud bogged motors. When removing the bell I ended up having to put the prop nut back on and using a pair of pliers pinched on the bell rod. Worked out perfectly.

[@danielmendoza1774]

you saved my motors josh! i was not sure how to remove these screws and had to angle grind my way through a screw once.... now i know that 3 mins of heat at 800F will do the trick too ; )

[@tonyhouk9047]

Josh, For installing the bell housing try putting a dowel into the shaft area. Use the dowel to control how fast the bell housing slides back on the stator assembly. Tony

[@pvenzELP]

I use a q tip with rubbing alcohol to wipe the bell and Also , you need to clean the stator as well , that's probably why the motor still had some "crunch". Also, its an good idea to keep cans of compressed air around to blow out the motors .

[@VideoBoat]

Hey Josh,, I know this is an old video, but I've found that using a tiny drop of 70- 90% isopropyl alcohol will wick into the threads and start to dissolve your locktight.. This will remove any threat of overheating your motor with a soldering iron.. give it a try on any locktighted bolt you have,, you'll see how it really loosens up.

[@P3nguinDarknes5]

Omg, blue tack! Why in the world havent I thought of this? Dude. Ty. So much. If I could fly a beer to you, I would - if only my drone could make it lol

[@flo-ridafpv5713]

JB a ZMX Motor Rep told me to use bearing oil if they have some time on them as grease wears away, and lightly coat stator face to prevent rust and shaft before reassemble.

[@kileyniemeyer6691]

I also replace the factory motor screws with a more robust screw when I get the motor to avoid stripping the screw in the future. 👌

[@gus8378]

I feel like twisting to get the dirt out might damage the stator if you have big particles in there. I believe the stator is composed of thin isolated sheets of metal, and rubbing them might cause them to make contact with each other. I don't know if that may cause significant performance loss tho.

[@kwyj]

i think you're right... just twisting to grind the dirt out is also grinding on the magnets and conductors. i did a little bit of twisting with a whole lot of canned air and it cleared it out pretty easily. If your lucky, the air might grab some of the mangetic stuff but taking it apart is the only way... i like the silly putty idea though... if i ever fly through iron filings, it'll come in handy.

Thank you for this. I had to drill out a screw head on my frame and got shavings in my magnets. The screws that come with a source one V5 area all junk I've now changed them all out.

[@bagofbones11]

I use contact cleaner because the dirt here in Oregon is very ferrous in my area. Just spray the motors while wiggling then back and fourth. Everything comes out after a second or two. Then I drop a little trip of lube if I've had to do it a bunch

[@scottmarshall6766]

Most of the time, if you just get em spinning, they will throw out even the magnetic particles. It's tough for a mechanical person to do, but it's really the easiest on the motors. Just swallow hard and hit the throtttle, they will grind a few seconds but in 10 seconds they will have thrown all the crap out and be good as new. I use tape to clean when I have to, any kind works in a pinch, and I usually have some in my bag. Use a 1.5mm driver pushed thru the bearings (from the bottom) to let the bell down without it slamming. Just push the driver thru all the way and put the threaded shaft over the tip. Then lower the bell in place. This is also the best way to tap the shaft loose if necessary. A drop of good oil once every 10 or 12 flights seems to help. (I like the Cobra oil, but 3 in 1 works well for 1/10 the price) Add the oil just before a flight and it will throw the excess off, and not attract dirt to the bearings. Oh, yeah, beware of the new Emax motors, they have a shim between the bell and bearings. If you're not careful it will fall in the grass and be gone. This shim keeps the bell from going on too far - the screw pulls against it. They are special, having a taper on one side to clear the shaft fillet. They didn't sell them separately when I dropped mine, not sure if they do as yet. Cost me a new motor to take the shim out of.

I use a small flat head to carefully scrape out the iron from the space in between the motors, so that the putty can easily get it out. (Not on the spacing with the mud). I also use a nylon brush to pile in up in one spot at the end of the groove so it’s easier to get off

Dang! That is what I messed up. I had a nice set of rotor riot hypetrain motors, and I had my motors get packed with mud and washing them out but that did not get it fixed. So I went to take the bells of, the first worked perfectly but the next two stripped out and I had to drill them. I was rather unhappy to say the least. I ended up buying two new bells and then this stripped out when I tightened them. Man I was mad. Thanks Josh I will be able to do better at fixing them next time.

[@diabolicallydan]

Tip for gently lowering the bell: use a plastic rod inserted up through the bottom of the stator and as you lower the bell in place you can use the plastic rod to control the seating speed of the bell... These bearings are so not a fan of lateral forces 👌

Good duct tape is so sticky that it can be used for the ferrous particles.

[@shaolin224]

Just getting into the hobby but been racing touring rc cars and buggys and truggys since the 80,s. But one essential tool we would have is a small compressor and electric contact spray like Dynamite or TA Emerald. Alittle spray and blow it out. Now they have an electric blower that isn't as strong but is more portabke. A cheap inverter from Harbor Freight ,at the field, would be ideal

There is a electric cleaner you can spray for dirt and mud. Also when you heat the screw the shaft will begin to absorb the heat which means it will expand. So try to heat the screw not the shaft.

[@Klawful2011]

I'm from New Zealand. You guys should consider yourself lucky. 95% of our beaches are volcanic iron sand. When we crash, the motor literally attracts so much sand, it looks like just a giant ball of sand. You can't even see the motor. When I clean, I use compressed air to get rid of most of it, followed by using blu-tack to grab all the excess sand particles. I use a knife to help push the blu-tack into every little gap.

Just a thought but that magnetic dust is probably the result of running motors with sand in them. Sand is super abrasive and can sand the magnets or other metal parts making magnetic dust. Also sand can contain metal on its own

Hey Joshua, What if ya got mud in your motors and windings - same process? Should I wait for it to dry or just go at it?

Wait for it to dry then turn the motor with your hand to grind out the dry mud. If it feels reasonably smooth (e.g. no rocks in it) spin it with props off to finish it up. Go fly.
