This happened to me and I had an esc failure then I saw this video very helpful thanks

[@powerofdreamx]

I had damaged lead (wire) from the ecs to motor and got this behavior. Good call.

[@Rascythe]

Totally had a bad bullet connection between my esc and outrunner motor! Simple fix! Thanks!

[@colin1992]

Great short tip ryan

[@KenDebono]

I'm here because I searched KZbin for 'noisy brushless motor' in an attempt to figure out why my wood stove's blower motor was making a noise sounding like the blades were hitting the metal sides. I already knew the rheostat (speed controller) was faulty, but had no idea IT could be the cause of the extra noises. Thanks for making this video. I'll replace the rheostat and keep the motor/blades.

[@bluemoon3407]

thank u ! mine has similar problem..now it was fixed...simple as that...

[@johnheater6697]

Literally saved my day. Thanks bro.

[@RCexplained]

Glad I could help

[@taitheguy85]

Omg, thank you! It's so obvious now. I didn't solder them at all yet. 4082+150a are just heat shrinked together for initial testing. Ok... Time to solder

[@leefordham8796]

Thanks. I just got a second hand set up. I think I got this scenario. I have a capacitor on the esc that got hot quickly. I probably tried it 3 times on the throttle on the bench for about 15-30 seconds. Is that enough to damage the esc/motor please?

[@petermcalley6208]

G'day mate again thanks for your help and advice 👍 🙏 Peter

[@RCexplained]

Happy to help

[@Ethio-RC]

thank you man.. you saved my esc.

[@varmintsniper2551]

My Sidewinder ESC started cogging and I traced it to the plugs. Cleaned it, ran it for a bit fine, then every time it flipped over or came to a stop, it started cogging. I never had any issues like this before. I’m thinking I need to try a more durable ESC.

[@johnpreston7605]

My brand new motor/ESC were a matched pair and it initially worked fine but developed the same stuttering after a very short time. I returned the motor/esc to the supplier and they tested it and found it worked OK and sent me a video to prove it. I told them that it was their problem and should do more testing as it appears to work but then starts stuttering again. Still waiting to hear from them after many days.

[@rainstorm5245]

Thanks. Big help…

[@sethgreenberg7725]

Thanks so much

[@ninehunnerdriver]

Thank You! I ran out of talent newish flyer trying to complete a roll. Went to flick toggle switch to switch on the gyro nothing and I stuffed it nose first into the ground! (Helps if you flick the correct toggle switch!) I had exactly this as in the demo. Sure enough checked the three wires between esc & motor looked fine, but double checked after watching your Video and one of the (3) wires to the motor had been detached! After extensive nose rebuild (pusher prop plane ) back in the air straight away. I'd started to question if I hadn't throttled back after the impact and burnt the motor/esc out, but I had! Just a loose wire Thank You!

[@RCexplained]

Great to hear you're back in the air! Sometimes it's the little things that can trip us up.

[@xibidit]

Hey I have a problem with my sensored motor in my touring car. it works like it should most of the time, it can slowly start up without cogging and so on. But if I pull the car backwards and slowly get on the throttle, it shouts out backwards even if there is sensors and everything to prevent this happening. Do you think something is wrong or is this normal???

[@pedrocruz5375]

Thank you 🤟 was able to detect my issue

[@RCexplained]

Glad it helped

[@greenhead4673]

Good 👍

[@trentthomas22]

Thanks for the video! I am experiencing cogging almost identical to what your video showed. However, all the leads are properly soldered and connected and it's still cogging. Can't even get the rotor a full rotation. Bearings and rotor are all good. Do you have any suggestions?

[@adireitinho]

Same here. Motor sputters ans goes back and forth ocasionally starting, running perfect after that. Is you cut power, ten again same problem. New motor, new esc, everything looks ok and it works fine without the prop. As soon as i install the prop, the problem comes back.

[@h.cedric8157]

Is this the same solution when the motor can spin(I have a BLiTZ SCT) but when on the ground it will just vibrate?

[@JoyGadang]

how if after run.. at long distance motor cogging, it is reciever or esc setting

[@kamalkamalesh8235]

I have 1 bldc motor and two ESC. In one ESC it's working good, when I try to run it on another ESC it's running only in lower rpm.. I can't run it in higher rpm. Do anyone has any suggestions?

[@rcboy6s909]

For sum reason my esc won’t turn off with the switch I wonder what it could be

so what do i got to do to fix this issue

[@omega_rc]

This just fixed my brushless 144001 lol I’ve had this problem for a month and unplugging and replugging the esc was all It took holy cow.

[@RCexplained]

Excellent, I am glad this worked!

[@tonyellis4773]

Hi your videos have helped a lot and. I was wondering if you know how too fix a mamba monster x 1515-2200kv sensored combo has forward and reverse switched and when I reverse the throttle on my tx it's faster in reverse. Thanks for ur time.

[@RCexplained]

Yes switch it in the castle software.

Sir make video on charging and saify of lipo battery please

[@dejgas3691]

Hello so my rc car have quite the same problem so i checked all the connectors as you showed but they are good. If i put throttle when all four wheels of the rc car are in the air it spins normally but it doesnt seem like full power and if i put rc car to the ground and press throttle it doesnt move it sound like it is lagging but if i push the rc car and press throttle then it moves and drives but it goes very slow (before that problem it was going around 40km/h) I hope you understand the problem and i am very sorry for my bad english because i have a bad knowledge in this language. Let me know if the problem is salvable, thanks.

[@jdplayz313]

Same bro still can't find out why it does that

[@digitalguy7859]

Not sure what my issue was. 1/8 scale buggy, new ESC, used 1900kv motor, new sensor wire. First time out, ran fine. Second time out it stopped working. Motor wouldn’t move with throttle input. However if I pushed the car then gave it throttle it worked fine (until it came to a stop again). I ended up getting a new motor and have had no issues. What could it be? I did take the motor apart and saw there was dirt on the sensor board? Could that have shorted the sensors out?

[@danbekistan]

Did you ever figure out what caused this? I have the same issue: 4x4 ran fine, then came to a stop and wouldnt start. Motor whines but requires push to get going, if at all.

[@digitalguy7859]

@@danbekistan I tried a new sensor cable and it wasn’t that. I had a race to go to and jest ended up buying a new motor. I did take the old motor apart and the sensor board was all crusty. I cleaned it all with alcohol but haven’t tried it again. So, I think the motor was the issue. First though check your sensor cable.

[@tedshen1716]

My motor heat up and inrunner magnet died. Got this behavior as well.

[@nubishobbychannel6462]

i had similar issue with 7700kv & 120A esc with 2s 120c setup. Sometime when i pull the throttle it seem unresponsive. Are this connection issue too?

[@RCexplained]

Remove the pinion gear and see if this changes anything.

[@nubishobbychannel6462]

@@RCexplained i try removed the pinion. Everything seem normal.. my motor rated 97A max. Does it related to esc? thanks

[@hansdampf3576]

is this a cheap blue esc?

[@nubishobbychannel6462]

@@hansdampf3576 im using hobbywing 120A. After i change to new motor problem solved. 👍

[@shadowplayerb827]

what is the problem if the motor works by itself, it depends on how I connect the three thick wires on the motor, sometimes the motor spins forward, sometimes backward, but I, and when I press the throttle, the motor brakes instead of turning the wheels forward, I have programmed the controller several times, is it it is possible that the ESC is dead, because the engine is running, or something else is involved?

[@RCexplained]

Sounds like your transmitter may have the throttle reversed.

[@joseywilds3133]

Program the esc

[@tikkabrno]

Have you tried swapping the two outer wires connection to reverse the polarity?

[@bljrpaham]

Hi ryan, can you help me here, I have an old (5 years old maybe) esc and motor combo from HW 150a sd the blue version with 2000kv sensored motor, 1st problem is whe i punch full throttle from the start at high rpm the motor stutters a bit then goes full throttle, but if I pull the throttle smoothly it wont happen, it only happe when I punch the throttle from stop position, can you help me fuigure out what happen? Your help will save me lots 🙏

[@RCexplained]

If you are running in sensored mode, it should not do this.

[@bljrpaham]

@@RCexplained Do you think its a bad esc? Weak capacitor or bec? Because I try to run a separate bec but it is still the same, thank you

[@RCexplained]

Not necessarily. Is it running in sensored mode or sensorless? A typical sensored esc usually has both options selectable through programming.

[@bljrpaham]

@@RCexplained yes it is running sensored, but after the stutters happen the esc detect an error in the sensored port, even tho I run it sensorless it still did the same thing

[@RCexplained]

Sounds like the error needs to be corrected.

[@deinsports8328]

I just want to know how to stop my motor from shaking my boat

[@JuniorManyawu-zo8nu]

The problem with mine is that even if I don’t connect the esc it’s still stiff I need help

[@RCexplained]

What's the problem?

[@JuniorManyawu-zo8nu]

@@RCexplained even if I don’t connect to power it’s still stiff. When everything is off if I spin with my hands the motor it’s stiff it’s supposed to move freely

[@RCexplained]

Did it change? Wat does it do in an rc? I'm searching for a problem other than your sense of it being stiff.

[@JuniorManyawu-zo8nu]

@@RCexplained I don’t understand but even if I don’t connect it to power when I spin it with my fingers it’s not moving freely. But when I connect it to the esc then when I put maybe 20% throttle it moves freely again

[@RCexplained]

Sounds normal to me. The magnets in the motor do interact with the iron core on the stator. If you feel it notchy with steps of stiffnes as you rotate the motor, this is normal. Check Temps when you run the rc.

[@nathanwilliams9338]

This is happening to me in my rc car after I sunk it in water

sir my autonomous not working, how?
