I run a Crawlmaster Magnum 11t in my Trailwalker. I can't tell if there is any less torque than a higher turn motor. That is a brushed motor masterpiece, thanks for the time and effort put into all the small details. I wouldn't hesitate to put it up against any other brushed motor setup on the market. The control and feel even rival my 3300kv Axe system.
From a newbie standpoint, my head has been exploding since I started looking into the specs. Sincere thanks for your experience and willingness to help. You help advance the entire scope of the hobby sharing your vast experience! Thanks again!
Very interesting info. Not something I would do at home probably but actually love the explanation. I feel very comfortable with hard numbers as opposed to opinion. Obviously opinions play a role some people like X instead of Y and so on, but Love the explanations. Thanks for sharing. I've had nine different Holmes Hobbies motors And they have all performed excellent. Currently my favorite and running in two of my rigs is your puller pro 2700kv w/Mamba X on 4s. Granted 90% of the time I'm only using 10% throttle but I absolutely love that I have that available wheel speed If needed.
I won't lie, I was just nodding and smiling through most of that. To many maths involved LOL! It was entertaining and I did learn some stuff from it so thank you!
Thanks for continuing to make great informative videos for this great hobby 👍 just got a 2040kv v3 and will be testing it today. Stoked to see how it runs. First time running an out runner🤞thanks again for sharing your knowledge 💥💯🤙🏻🍺
Thanks to your videos, I am going to run a Revolver V3 2500KV 10 pole on 4s in a capra with a 3 gear transmission, and underdrive the rear diff, and rear portals, rather than overdriving the front, and if needed, play with the spur and pinion gear to get the right speed. Just have to wait for a Crawlmaster Mini ESC v2 to come back in stock locally
Can the same principles and testing you are doing be applied to brushed drill motors (Dewalt/Milwaukee for example)? Can a drill motor be used with an ESC?
I know it would be prohibitively difficult to engineer the mounting, but I wonder how different the performance would be with an out runner motor? Smoother and more torque?
Hey John! I have an axial wraith with the stock 20T motor. I’m looking to get a little more speed off of 3s. Would the 2700kv or the 3500kv puller pro be a better fit? Thanks!
@@Cooldibs I run the 3500kv puller pro with a 10t pin and its perfect. It's slow for crawling yet has the power and speed to do a backflip of small stumps and such bashing around. I have 3 wraith 2.2 rigs and love them. The 2700kv 10 shooter is another amazing motor for the wraith. Can't get any smoother slow crawling then those. But needs 4s to have the wheel speed most want. I've even ran my wraith on 4s with the 3500kv pp. It never got hot. Even ran it around the yard in tall grass and full throttle up and down the road a few time's and only got to 130° temp on the motor. Esc hit 150° witch was fine. Just gear down and injoy !!!!
Question for everyone here. I'm working on my first kit build and just wondering about the longevity of brushed vs. brushless. How much upkeep is there to a brushed motor? My only other rc right now is a Gen8 Axe version. Just curious to maybe try out something different. Thanks!
Great info I'm looking at upgrading my 540 21 t sport I see why the pro is more expensive I'll let my local hobby shop know I was told the only difference was the pro is rebuild able
@@stompindakka3222man I sure hope nobody ever gets saddled with anything more than 35t in any crawler. Otherwise they are painfully slow. My son's 1.9 wraith has almost 400 miles on a 27t 540 trailmaster sport(good balance between speed and power on 3s.) But I've also used the 12t trailmaster 550(my favorite) trx4 21t trailmaster 550 wraith,and a 12t crawl master Vattera ascender. All have tons of miles, and none were as much as the rc4wd.
Hi John I run a magnum motor in a Capra paired with a HW 1080 and it’s pretty smooth. I was wondering if it would be worth the expense to change to a crawlmaster mini? And yes I realize you might be a little biased 😄. Always love the tech videos!!
You talked about breaking in the motor. There is a guy around here that I think mixes kerosene with his water and breaks his motors in. Somehow the motors that people buy from him are so much faster than everybody else's. We are supposed to be running a stock Titan 12 turn traxas motor. How does he get his so much faster than everybody else's. I do use water to break mine in then I flush them with connection cleaner then oil the bushings. Thank you and I love watching your videos.
2 weeks late but here's the short answer, kerosene works as a lubricant and detergent, it cleans more of the carbon off the stock brushes than plain water, and it also allows for a more gentle/slower seat in of the brushes to create better contact. But this also shortens the life of the motor, however in racing it really doesn't matter since you're changing them out regularly. And at $20 who cares. Haha
So if torque is better in the 21T area and 21T can easily be geared correctly to a crawler; what is the point of higher turn motors (beyond going slower because gearing would take care of that)?
Also possibly to a small extent efficiency, higher turn motors with higher voltage will have less wasted power. Not a great trade IMO, the higher voltage also wears the brushes faster. Don't forget not all applications have so many gearing options readily available.
@@HolmesHobbies so than what about 85t to 55t those are beyond slow when geared down. Is it just the simple fact that people will buy it so there is a supply? Or is there a reason for those?
I bought a trx4 used and it came with a hobbywing fusion but it's the 1200kv motor. So that's the worst option of a brushless motor for me? Is there anything I can do to improve or help it gearing wise? It seems pretty strong on crawling but not much wheel speed
can'T wait for the results so more torque ? 3 slots 550 21T 3 slots 540 27T 5 slots 550 13T 5 slots 540 16T my prediction based on the info in the video and your comments
@@HolmesHobbies Yep it's a Krawler I built mid 2000's & was featured in RC Drive & Car Action. There's video of it on my channel I recently shot. Thank you for the info. I'm trying to stock up on some parts.
Honestly, if those motors aren't worn out I'd just keep using them unless you want to save them. Since it's not a comp rig you could use about any 540, something like a regular torquemaster or crawlmaster would be just fine.
@@HolmesHobbies I need brushes & can't find them like most parts that are broke or cracked. Thanks a lot for being honest & letting me know that! I much appreciate that! I would like to just keep using them. I built 66:1 reduction units but I can't even source an 8T 32p pinion with a normal 1/8" motor shaft so I went with a hardened 9T hopefully it works.
@@HolmesHobbies Can you turn the end bell 180 degrees to reverse the rotation on those motors you mentioned? I need to be able to do that for the Clodbuster.
@@HolmesHobbies If you had a choice to buy an X-maxx for $500 or an 81 Honda for $500 which one would you buy. Which one is more practical? I am interested in this brushed outrunner technologies 🤔
LMAO was just thinking of those "worlds simplest motor" where you have AA batter sitting on a magnet and you can bend a paper clip to make it rotate around the battery... This is totally an outrunner motor!
@@HolmesHobbies I have a 11T 540 CrawlMaster Pro in a portal rig. Sometimes I feel like it is "squishy" when I need more torque. Are you suggesting a 16T is a better balance between wheel speed and torque?
Please tell me you didn't just do a 30min video measuring motors and plan on following it up with a homebrew math chart without planning on dusting off that old dino to back it all up.
Sorry, but your resistance test has little to do with with torque. It's telling you something about the losses and maybe the efficiency. Torque of an electric motor, no matter of what kind, is related to current, number of turn per coil, pole number and magnetic flux density. That is according to some physicians like Faraday(BEMF), Lenz(negative sign of the BEMF), Lorentz(Lorenz force), Ampere(see definition of the unit Ampere), Webber, Tesla(not the company),... Sometime reading books is better than watching YT.

What if you spin the armature at a set RPM for each motor and measure the voltage produced by the motor?
So if Resistance on the Better Motors is Lower does that mean the Batteries will last Longer?
So if torque is better in the 21T area and 21T can easily be geared correctly to a crawler; what is the point of higher turn motors (beyond going slower because gearing would take care of that)?
Some people don't want all that wheelspeed. Slower motors are easier to control.
Also possibly to a small extent efficiency, higher turn motors with higher voltage will have less wasted power. Not a great trade IMO, the higher voltage also wears the brushes faster. Don't forget not all applications have so many gearing options readily available.

A comment to help the algorithm.

My absolute favorite has been a 12t trailmaster 550 trx4, or my scx10ii with a 21t 550. Always 3s.
Coming from using 2 Astro flight pullmaster motors using all old school stuff what my best bet for crawling?

I just want more wheel speed than my tekin 35 will give me.
Go higher than 1500kv or use a faster brushed motor like a 30t or 27t
@@HolmesHobbies I did! Probably too much but I’ll gear down if I need too. I got the Magnum 11t yesterday. Can’t wait for it to get here. Thank you!
I’ve come to realize it’s not speed I need. I just want quality and I definitely think I made the right choice this time in the Magnum
I still have the tekin 35 I can go to if it’s too fast for me.
Broke the Magnum in yesterday. It’s all ready to go. Can’t wait to get outside and climb
way too much too quick. barely made it two minutes... i wish i was smarter. off to find a more simple video :(
