Ive been running your trailmaster sport 27t for about two years run it in mud and water all the time best i do to it is try n run through a "clean" mudpudle and its still going strong
I'm drawn to creeks like flies to manure so for my SCX10ii RBK I bought the Trailmaster Sport solely on your recommendation--no explanation, just trusted your judgment. Now I know why it continues to work so great. Keep up the awesome service you provide to the hobby community. Cheers and thanks.
I'm glad it's worked out for you!
Great video.
You confirmed my driving style: no water above axles, no splashing water!! (Staying away from water...)
Thanks
The George Clooney of RC!
Thanks for the info!
just ordered a torquemaster expert 550 21t from you. Anxious for that beast 👍👍
John keep up the good work with the video's. I'm running a Holmes sbm and mamba max pro esc. In my k10 vattera. The motor and esc. Are water proof but i only run in shallow water never above the axles.
Really great info. Going to buy some Holmes motors tomorrow.
Awesome, thanks for the support!
i love your videos thanxx so much i have learned soo much about crawling and motors and about the esc
Thanks, plastidip on sensor harness and all connections does a good job and stays in place for quite some time before peeling away and at the same time, exacto knife or even a steel pick will quite easily remove that stuff for maintenance or diagnosis inspection.
nice informative videos 👍
Man you had me rollin when you made yourself laugh 👍🏻💯
Same lol
Would like to see more videos. Also will be buying another brushless sensored setup from you soon.
Very clear and understandable, thank you so much!
Vasaline works good also (cheaper longer lasting )
Nice video!!
Hey John Holmes, what's the best motor for my wife's vibrator?
10,550 Kv brushless.
Diesel.

This is great info 👍
I have run my R/C trucks in salt water. Ocean water is very destructive to almost everything in your R/C truck. I use the cheap Tamiya Mabauchi non-rebuildable brushed motors. I can usually get several runs out of them before they die. Ocean water also destroys all the metal parts in my R/C truck too. I spray WD-40 in my motor and on all the metal parts. This seems to slow down the damage done by salt water. I will do a complete tear down of my truck. I clean and re-lubricate my motor and all the metal parts. I also lubricate the bearings too. This is a lot of work but necessary if you want to keep your R/C truck going. Motor spray can also be used to clean parts too.
Keep going brother. good video
Thanks!
When I first started rc racing we would put a balloon on our motor and esc when we wanted to run around water. Of course that was over 30 years ago too.
I used to do that too!
@@Shadows-RC that was a risk we had to take.
love the duber ;)
the secret to life is a clean tater!
We know who watched more than a few seconds :D
MMM taters
And 're-lubing your bearings'.
My son, tater tot
Lmao i can tell you're trying your hardest to be serious throughout the whole video. You deserve more likes than what you actually get man. No cap.
Ok I use to race back when the jrx2 first came out donuts been a few years sun I’ve raced. So I’m getting back it into it again but I’m playing catch up on technology saw your video on brushes vs brushless motors very helpful. And I’ve seen vids on batteries. But why did they stop running nicad batteries and can you use nicads in a rig that uses Lipo batteries
Your videos rule!
Thanks for all the good info and I guess I'll be getting a couple inexpensive throw away motors.
What do you think about WD-40 after cleaning the mud and grit out? It will displace any water and stop rust in the short term.
better than nothing! We make the TrailMaster sport as a premium quality "throw away" motor.
I have a Bomber that I Iove to go fast with but want to get better at crawling so I put a two speed transmission in it. I have two spur gears and a handful of pinions to play with so which Trailmaster motor would you recommend? It is a heavy beast. I have a Hobbywing brushless setup right now but we get so much rain I think I'll use it in something else.
2700 TrailMaster Pro is a good all around choice for brushless. 21t TrailMaster Sport is great for brushed.
Do you use water proof synthetic grease on the bearings? There are many brands of marine grease that work well in water. Also wouldn't you just change the battery and load up your motor so it gets how and evaporate all the water then clean the motor with rubbing alcohol and regrease ?
I bought my tamiya CR-01 kit 9 years ago. Put it together and never ever did any maintenance on it. It is not used very often but alwaus take ot with me every year on wimtersports holidays, summer holidays and just wil drive it now and then in the house or the garden. Drive it in water with the transmission and motor totally submerged. also drive it in loose sand and mud. But never let mud go up the motor or gearbox. after the drive I just make sure there is no mud left that will keep the metal moist. Just hose the wheels and axles. But it is still going strong. Only the motor barrel bend lips get light rusty and nothing more. To be honest, the rigg starts to ride a little louder than ot used to when it was new. But again. never ever did any maintenance on it. So I think just try to not get mid in it bexause that will damage ot more easy. Just water in my case not so much
.. What about the out-runners? I'm genuinely here looking for how your revovler would fair with such conditions. I guess it wasn't around back when this video was put together? xD
I'm here for the exact same reason.
you get jam in dem taters! lmao
I just bought y'alls new stubby Rock Crawler Motor WaterProof 3300KV Puller Pro BL 540 Stubby i hope it last longer than my first motor
Thanks!
My Tater is working fine and I run it in my TRX4 everywhere - Holmes Hobbies 21t Brushed - 😎👍
Super old video obviously, but I have had extremely good luck running my brushed motors in the mud and dirty water. It seems that the trick isn't keeping the water out it is making sure it can get out once it is in. I had tried a brushless system in my trx4 because "it would last so much longer" I was told repeatedly. Well it didn't I found that I had a false sense of security since it was "sealed" well just like you said the water found it's way in and then it couldn't get out. I am awful with maintenance on my vehicles, I tend to wait until a can't stand the squealing and squeaking and do a mass maintenance all at once. My current motor is about a year old I have never pulled it out, never oiled it, never done anything for it and it hasn't died yet. It finds water or mud nearly every outing and several times it has been stuck rusted where I parked it. I am a holmes believer, I appreciate you making a motor that has withstood unimaginable abuse that it was never intended to endure. Did I mention I bought it used?
How will your outrunners fair when submerged? Also very curious about when we might see a full sized Crawlmaster ESC and if it have the ability to run outrunners quietly.
They can rust but run underwater just fine
I will try to make this short, but this issue needs some explanation,
I buy the low end vehicles, and rebuild them for durability, and hopefully more speed.
I've purchased a couple of $20 ESCs for two current projects. 1/12 Virhuck L01, and WLToys A979B. The issue is with swapping out the electronics. I bought receivers, Servos, ESCs, and Motors. The A979B was already fitted for a 540 motor, so I bought a 540 4300kv motor, and 60 amp ESC. For the Virhuck I bought a 2845 5900KV motor and the same 60amp ESC.
Both setups have the same issue. When I pull the trigger from a dead stop, they stutter and jerk for a couple of seconds before taking off.
I've switched every component including Transmitters and it is definitely the ESCs.
Yeah they're cheap, but I'm turning 70 in a few months, and only run for fun in the back yard, or open areas (empty parking lots, etc)
So my quetion is, what ESC do I need to look for that will stop the motors from stuttering on takeoff.
I pulled an older ESC off one of my other trucks, and there's no stutter at all.
That esc is also a no name, that I'm pretty sure i paid about $20 for,
There's no visible difference, and I've run the cars for as much as ten minutes and nothing heats up.
Help Me Please - Mr. Holmes.
Castle and Tekin are the best ones for launch, but being USA manufatured will be 5 to 10x the cost. Probably not worth it for your use, just roll into your throttle a little slower and deal with the cogging.
How do you oil the brushed sealed motor bushings and bearings? Also could I clean the motor submerging it in brake clean? Cheers
I just got the trail master sport 55t should I do a water break in before running or just wire it up and go
Just wire it up
I was curious if you had any tips re: your revolver motors? I'm super keen to replace the traxxas 21T in my truck with a SW4 and a revolver but I was curious about taking care of the Revolver motors? I have to admit with the 21t traxxas motors being 20 bucks a piece I typically just douse them in wd40 after a water run. from what I can see it doesn't look like the revolver motors are sealed?
They are pretty easy to clean out. WD-40 would be fine. Just be sure to keep the bearings lubed!
What is the best ‘motor for running in water?
Thanks for the education can't wait to try your products..✌
What if you run in dust? Like sand? What would you recommend?
I got a Leopard 4082 1600kv motor wet in salt water, lubricate the bearings but I don't know if I can pour 656 or oil into it through the grids that you see, what advice do you give me?
What is the recommended bearing lube for brushed or brushless motors?
0w or 5w motor oil is fantastic.
I tried hooking a tater up to my rc. It would do anything! What am I doing wrong?
i just buy new scx10 ii kit, and now i should make decision of choosing 1 motor and esc (combo better). i already watching all your explanation about brushed and brushless motor. but i still confuse to choose what is the best motor for my new kit. i always playing in water and mudding crawler. for me, price is not a big problem, bcs i want the best. i already open your website and really a lot of choice. can you give me what is the best choice for me? motor and esc for my new kit? i want high torque, dont care about very fast speed. thanks a lot for your advice. Good video and have a nice day
What if we open the sensores motor and spray plastidip in the sensor port. You have any experience with that?
Hi I'm john Holmes and if I don't see you later, goodmorning, good afternoon and goodnight! Alrighty then. I come here when I need a manufacturer view on things.
between yourself and The RCnetwork I am fast becoming a pro at this, lol
I noticed that many modern brushless motor leads come out the motor with a rubber boot, leaving no metal exposed. Other older motors have open connectors or tabs to solder wires onto. Is the completely sealed booted a better option for moisture or does it not matter, since you mentioned moisture being drawn in jackets?
really doesnt matter either way. its cheaper to pull the wires out of a boot. Its more expensive to have a nice solder tab
What about using a r/c boat with a brushed motor in saltwater? is there a way to clean it out after the run? I'm not saying the motor will get super wet, but it could get drops of saltwater into it. Is there a way to clean it nice and good? or is it doomed?
Hey Holmes, what's the best battery to use to make the stock summit run faster.
Don't have a summit ,but more voltage is normally a good answer.
Anything that's not a Traxxas battery? 🤣
So you started getting into it and then you got interrupted by the tator. I have a right that's fully waterproofed and did a lot of water crawling, not when I got to crawl with it, it kills batteries super fast. Do you think that's because of gunky brush arching?
Yeah, brushed motors lose a lot of efficiency once the tator gets gummed up
What would you recommend for a trx4 and a 3s
TrailMaster Sport 21t 550 for a stock replacement. Puller Pro 540 2200kv with BLE or Mamba X ESC for sensored brushless upgrade. Or Revolver 540 1800kv and sidewinder 4 for lower cost sensorless brushless.
What about your Revolver Outrunner motors? can those be run under water and/or mud?
Yes, but mud can be pretty rough on them. water, no problem. Just dry and relube so it doesn't rust
Can chop out std bearings and e clip for sealed stainless steel replacements
Thanks boss. May be worthwhile exploring ceramic bearings too, dam good stuff if you know where to look.
I see others showing your revolver sensored out runner motors but on your site it says they are sensorless
We had quite the difficult time making them sensored and reliable. The new firmware on the TrailMaster BLE and the mamba X controllers have much better sensorless control though, so now it is possible to run them sensorless and still have great crawling ability!
Hi john , I have a few 1/16 scale rigs , but have been out of the hobby for years .
I want to know your recommendation for an upgrading Motors an esc's for my Mn 90 land rover and others
Thinking like 380 motor with good range of lipo battery voltages. Love the crawler scale driving with trails , and abilities to get totally wet n muddy ..
Now I know you have the the Homes Crawlmater pro , do you have anything with outstanding performance like the Crawlmaster in a 380 ... looking for your thoughts and recommendations for this and esc..
Thanks much .. Cheers from Alberta Canada.
Working on a 380, but don't have one in the catalog now
@@HolmesHobbies so what setup would you recommend then John , ESC and Motor wise , what would you use if it was your 1/16 crawler.. ty.
What about making a water proof enclosure?
I'm sure it is possible if you have the gumption.
what gauge motor leads Yall put on torque master expert 550 21t?
14 or 13ga. dun forgot what we currently have.
+HolmesHobbies if my esc wire is a smaller gauge than motor wires will it be bad?
nah, not a problem.
+HolmesHobbies meaning my esc wires is not as thick gauge as motor wires. will it cause trouble are harm later on?
gonna wanna get a motor from u guys pretty soon and i was wondering whats best for some good speed to get up them dirt hills but still have that slow rock crawl ability
Puller Pro 540 3500kv all the way
man see i had brushed motor its worked in rain, and it was fine
after 3 days i flip it then its worked but with time slower and slower until it stop work
its meagre 500ohm and its dc motor, when i connected it to powersupply power truned of because of overcurrent
is it mean that if i dry the motor it can come back to live or i lost it?
Comm is probably shot, maybe brushes too short
If you try and shoot a gun underwater it will blow up. lol.
I thought that only happened if it's not fully submersed aka just the tip
Are brushless motor on rc car waterproof?
Is water break in still a thing for today's motors?
Are the motors in a drone water resistant?
by nature, yes. But not rust resistant.
How many blooper reels did u have just trying to make this video?
I pretty much one-take every vid and aim for little to zero editing.
i thought you will put in water test .
What ifff it never shut off lol then it couldnt cool off to condense
The best advice always comes from a dude with a beard.
Think with your dipstick Jimmy!
At one point when I was little I thought brushed motors had cleaning brushes inside them lol.
Thought this was a motor video then we get wet add lubes start talking cans and sucking. Lol
The green one doesn’t like water 👌🏻
Wait a minute are you THEEE John Holmes?-
Theeeeeee
oh shoot, thought they were BFF's
Why not a realy waterproof brushed motor (completed sealed) for crawlers? Even water wear out brushes and muddy water wear them out quick.I think heat is no problem under water.
Water still seeps in around the bearings. Hobbywing did a pretty good job on the axe and fusion for water tightness but they still come up rusted after about a year of water use.
I am working to make some more resilient motor housings, but long term it will still require occasional cleaning. There is no such thing as waterproof motors. They actually survive better in clean water when open frame. Mud just kills everything in time.
@@HolmesHobbies many thanks explain why.I hope for a brushless smooth waterproof motor to can service easy for though conditions.
I like tater tots too, with eggs and bacon !
Cool Crawlin RC I.n.c., what is a tater tot?
Brushed silver motors and the other ones cost pretty much the same
Clean it after every run who has that kind of time I crawl through mud and water them place my car on the shelf till Iam ready to run through mud and water again and I haven't had a problem . But some people need constant CZcams content .
I don't know why, but you remind me of Robert Downey Jr when he was playing Tony Stark for some reason, only you know about the wonders of clean taters, dielectric grease and lube.
its quite easy to waterproof motors........ i have an outrunner motor, and its nearly impossible to waterproof it since the outside turns. and so far, there are NO waterproof outrunner motors.
Tater
I never thought I'd laugh that hard to a motor video.
CAn't stop thinking about taters!!
Im from Ireland i know what you mean P tato's :)
Good hygiene if you get your tater wet...got it :-)
*muffled laughter from the bottom of a creek*
Hey napoleon, let me get some of your Tators.. No! Go get your own! Gosh!!!
Eat up yur meat and taters son.
i know what im about to say is a big NO NO for some people ... but a plastidip bath will solve most if not all problems with water... servos and ESC included to... mud on the rigg not in the tater
plastidip doesn't adhere to the components. Part of the "removable" aspect of it. Get one hairline crack and that water will surround the entire object inside the dip job. We have seen way too many failures come through because of plastidip.
@@HolmesHobbies I've used Corrosion X spray/dip to waterproof RC and other electronics and I've never had a problem. The hard part is proper disassembly to get adequate coverage.
