Dude brushless motors can run under water…
It is more likely that when you did that big jump one of the stator wires broke off.
I know because I fly outrunner motors on my quads in the heavy rain.
And my inrunner boat motors get soaked all the time too.
The oring seal is to keep dust out.
Interesting! The wires look okay but burnt. I'll take another look at the old stator. But I'm sure no wiring came off. All was intact.
Keep the good work up Amo well detail video👍
Thank you it's much appreciated
Great 😊Detailed video Amo
You guys make excellent content 😊
Thank you bro for your continued support! It's really appreciated!
Quite a few people had issues with the gyro. That seal don’t look great to me. I remember seeing someone add an additional silicon seal to make it water tight. Still. Great vid. 👍🏻
Thank you! I really appreciate the support!
I'm glad to hear I'm not the only one!
Silicon is a good idea, just putting the right amount
Great little channel this I just ordered mine last week, just waiting for it to come. New sub here
Thank you! Really appreciate your support!
You will have endless fun with the bike. Yeah, all rc's have their downs, and this issue should be rectified. However, this bike itself is awesome !
@thercstore. Great stuff. I can't wait. I am in uk bristol. Your channel is great pal good information 👍 look forward to more videos in future keep it up. 😊
I watched your video on this stator issue as I had been warned to keep
Mine away from water and wet grass .. I have been having a blast with the promoto over the last few weeks .. I was running today switched fly wheel off promoto sat for about 45mins plugged a new pack in and went to spool the flywheel and nothing but clicks like when u only plug 2 leads in a motor rather then 3 it was making a stutter .. stripped it down to find the stator casing extremely hot and had the same burnt out windings as yours even the same place on the stator as yours NO WATER OR DAMP .. was running on dry loose dust and dirt .. hopefully warranty will cover .. but it’s worrying that it burnt out with normal use
no way! that's crazy! Guess they are temperamental after all. I've been waiting for dry weather to use mine again. Guess it makes no difference then?
@@thercstore. watched ur vid when I first got it and saw yours had burnt out and kept it in mind to avoid water or damp .. hence I thought I would come back and explain what happnd to mine .. was running it around on flat dusty oval .. had first run of the day using only about 70% of the 2s pack .. then had to swap out an ARRMA diff for my son .. went back to bike about 45mins after switching off last thing that was done was the flywheel switch and drag brake.. it was still running fine before I spooled it down quiet and smooth .. new pack in and went to spool flywheel up and nothing but stutter so either the burn out happnd during spool down with drag brake or it shorted when I switched it back on and flicked the flywheel switch .. I will come back and update when I get the bike back .. did u lube ur chain as the only moisture I could find was around the front sprocket pinion .. from the chain lube .. I’m wondering if the flywheel is ingesting the chain lube moisture and shorting ?
@@highflying82 I did lube the chain but surely it should with stand that.
It would be good to hear what the outcome is of your one. Just to cross reference and see what is causing the issue for any future issues.
I was in the same situation. I knew the answer. A little bit of water makes it fire. I was beaten twice.
That's not good! I'm surprised Losi hasn't bothered to make a permanent fix on this.
Very interesting. Haven't seen this issue either. I have one and I've ran 4 packs through and done a lot of aluminum upgrades without issue. Great content though, best wishes! 💯
Thank you for watching it's really appreciated! A few people have messaged me with the same issue.
Strange???
Thank you for your support once again.
Really????? Crazy I haven't heard of it here in the states. Kevin Talbot recently covered the Promoto and in his video he was running it through deep water (horrible at driving it by the way). I definitely feel you had a bad seal probably due to bad installation by factory. I appreciate you putting out issues such as this as it gives me insight into what to watch for. Thanks, and best wishes bro! @@thercstore.
@themidwestconnect thank you for reaching out! It's highly appreciated!
It probably was a bad seal. Well, I hope so!
Great video.
I think when mine comes back I'm going to strip it down and put a layer of vasolene around the seal for extra protection.
I thought about this as an after thought using marine grease.
@@thercstore. Yeah, I've got some Morris waterproof grease thats used on narrow boats.
I think I'll use that.
Its back now and fully working. They also sent me a free chain for my troubles, so very happy with the service and outcome
@MarkJones-re3po oh nice!
I'm glad it's done. I can't wait till the weather improves so I can get it back out.
Hi, literally ordered mine today now that some places have them in stock. I’m so glad to have come across your “really helpful video” showing this issue, muchly appreciated 👍🏻😎 Thinking it might be wise to do some pre-preventative measures before it’s first run by using some Vaseline or marine grease to help with the waterproofing etc just to be on the safe side.
New sub here 👍🏻
Firstly thank you for supporting the channel! its really appreciated.
150% its worth taking the measures against the issue as I don't believe that a simple replacement of parts will fix it permanently or for any long length of time.
Mine let out the magic smoke on start up the second day I owned it. Was the stator. They paid for return shipping, repairs and shipped it back to me.
Its crazy hey !
That really scary I was just going to buy one I guess I'll hold off for a bit.
A few people around the globe have had the same issue.
Don't let it put you off. It's a great bike and so much fun. If the issue does happen, it will be covered under warranty. If you're out of warranty, the part costs £50.00 to buy.
Great video, mine had the same problem, just got the stator after a 3 mounts wait. Witch side the crusher goes in? Thanks
Thank you for supporting the channel. Its really appreciated. Look like the stator is a popular replacement part. Unfortunately I can't exactly remember which side the washers were on as this was filmed last year. I've not had it apart since then. Sorry I couldn't help on this particular question.
Defo looks like it was that last jump. You could hear it hit the base on the ground in that last big jump and it was running fine up until then so a bit of a coincidence that it then stopped working. I won’t be doing that with mine.
I personally believe it was the water. As it had water residue in the stator itself.
But you're right it was fine up until the jump! Or did the jump move the water into a place it shouldn't be. Who knows!
But hey, it's a fixed and good to go!
Hello super ta vidéo !!!! oui j'ai vu un autre garçon avoir le même problème que toi suite à un passage dans une flac d'eau . !!! je pense que la moto n'aime pas l'eau .. Stéphane de France . ..
Thank you!
Wow ive had mine for months now and ive had it through puddles long wet grass and sent it to the moon and mine has been absolutely fine no issues as of yet!! you must of got one of the unlucky ones..
May well be!
I'm glad yours is fine.
I guess only time will tell!
Thank you for the support. It's much appreciated!
@thercstore. hope you have more luck with it going forward dude
@typergaz82 Thank you!
Ya, long dry grass vs shorter wet grass. I've seen other creators avoid wetness altogether. For the price, it should run whithin a reasonable amount of wetness. Thanks for the update.
It's a new product. We all have a lot to learn from curve. Thank you for leading the way and showing us the internals and giving us a base for troubleshooting purposes own units. Well done.
Your welcome!
@@ghoormann thank you for the support it's much appreciated!
Same happend to mine coverd under warranty mine was
Glad you got it sorted.
Fingers crossed its not a on going issue!
AMO that's why there is Q.A. and sometimes a bad one gets by. Yeah I know bummer it's you this time. But so far for this problem it's only one.
There has been a fair few now with the same issue!
But it's cool it's a hobby at the end of the day and things happen!
Thanks for the support!
Much appreciated !
This just happened to me. I was driving it in long wet grass and it started smoking. I guess I'm buying a new Gyro.
The issue is the stator. I would go back to your retailer as it should be covered under warranty. However, if you're going to replace it yourself, it's a stator you need, not the magnetic gyro.

Mine just burned up the flywheel motor today as well. Burned up windings and the receiver lead burned right out of it. There was no water in the flywheel case though.
That's strange. Maybe there's something else causing this to happen 🤔
Seems to be a common issue.
@@thercstore. I wish I knew what caused it. My son was running it, went to pick it up after it fell over, said "the gyros not working" and picked it up. By the time he got to me, it was letting out the magic smoke lol.
@@kwiktsi1 That's such a shame. I haven't had the chance to run mine since. But I will get it out for a run as it is so much fun when running.
There will be some findings and answers soon I guess!
Have you gone through warranty to have it fixed?
@@thercstore. My LHS warrantied it for me and I swapped it out. Haven't used it yet either, just changed it yesterday, but all seems to function as it should. It's a bit more quiet now too, don't know if it's due to the new stator or because I lubed the flywheel bearings lol. I don't see how the stator would make it sound any different though?
@kwiktsi1 it's most likely the fact you lubed the bearings. I did fire mine up, and it sounds just how it did before the issue.
You need to get youself a set of Allen hex screwdivers, rather than using allen keys. That's assuming you dont already have a set.
All ready, have a set!
I use them on some bits. it just depends on what I'm doing, I guess.
Thank you for watching! Much appreciated!
Water will mess stuff up. One lil short and puff.
You're right! Let's see if there's a plan of action from Losi moving forward. I don't really want to go down the silicon route, learning now from the comments some people have.
Thank you for the support it's really appreciated!
utiliser TROPICOAT en bombe pour rendre étanche l'élèctronique sensible
Motors can run under water i got one of them for me son they great been across water logged grass the lot even washed it off with hose pipe keeping away from receiver of cause ran about 15 batterys in it already with out a proplem id put that one down too a bad motor me self to be fair probleys a one off
It seems to be a common issue. I must of had approximately 8 to 10 people email me abut the same issue.
Plus those that have commented here.
Mines was okay to begin with until I had the issue.
Wet grass didn’t do that, the puddle you ran the bike thru did that! 🤷🏾♂️🤷🏾♂️🤷🏾♂️
I believe I'm not the only one who had this issue. a fair few people have had the same issues. But hey, it's all fixed now.
Thank you for supporting the channel. I really appreciate your support.
i Had the same problem and i figured out what is happening there and fixed it myself. This flywheel brushless stator becomes very hot during startup and running. exact behind the stator sits the brushless ESC for the Stator motor. You can see it, when you remove the orange cover of the stator. So the ESC gets the direct hot temperatur of the stator and fails (shorts inside) and causes the stator to burn. i removed the esc and connected the stator to an external 20 amp ESC which i placed somewhere else in the bike. Problem solved forever. This flywheel construction from spectrum is designed very bad and waits to fail. I am very disapointed about that for this expensive price.
Be care ful while connecting the new esc to the stator. Stator motor can spin in both directions but only one direction makes the bike drive stable, if you connect the connectors wrong, the bike will not drive and fall over instantley. Than you need to open the bike again and change the connection between 2 of the 3 cables to make the stator running in the right direction.
@@veryluverylu8298 This is amazing!
Thank you for sharing the information it's really appreciated!
@@thercstore. you are welcome my friend
Where is the fire?
that's why the companie's brand is named "lossi" 🙂
lol
Probably just a bad motor.
Stator failed! Due to water ingress. We have done a tear down video on our channel!
Thank you for your support it's much appreciated!
