The Crawlmaster Pro is so silky smooth, and yet still has more torque and a better drag brake than I expected.

OMG you had the shirt made..... I can't handle you LMAO😂🤣

Wow, great video John!

John, that is the BIGGEST Wiha screwdriver I have ever seen! I have the full line of flat/phillips, torx, allen and nut driver WiHa's. Love 'em, not the best for torquing RC stuff, but it makes us stronger. Thank you for bringing back the Casio calculator watch. That was the IN thing for us geeks back in the early 90's. It was like the next iteration of the pocket protector. I'd like to see you do a video where you unleash all the electromagnetic and mechanical engineering knowledge that you have that goes into these motors and ESCs.

Do you have a video that explains the difference in turns? I appreciated your clear explanation of the difference in the torque and crawlmaster, interesting.

Another great video! I always find them helpful and enjoy them. If only we had KZfaq in the 80s!

Hey John happy holidays and thanks for the education I have come to really appreciate knowing about the quality of the products I trust ..use ..and recommend your product line is for those of us who want nothing but the best✌

Most enthusiastic video introduction in RC haha, and that shirt!

Awesome vids man keep it up. Ordering one of your motors tomorrow super pumped

I love this video thank you

Here I am in 2024 🤣. Retro sport motors are great. Really the only motors I run on my kits, other than Mabuchi. I’m old school and love the sound and feel of a brushed motor. Also great customer service from this company 👍

Great video bro appreciate the tips

Hi John. These are great videos, thanks for making them. I actually came to your channel looking for an explanation of brushless motors for my 12th scale pan car. I race these in the UK, on carpet. I am curious to find out about how I should set my motor in terms of timing, and gearing. You mention these topics, in your other videos, obviously in the context of your preferred crawler class vehicles. You also talk about the batteries and their C rating. I would certainly find it useful and I suspect others would too, whether into crawlers or any other RC hobby of what considerations you would make in determining these things. In the battery vid, you mention that if you raced and needed to be going 30-40kmph for 7 mins (I think) that you would need a higher discharge (C) battery than if just going trial running for an hour plus. I wonder if you could make a video that covers these things, in general, so I hear, torque, power, Kv (or back EMF), rpm, amp draw, esc heat. I'd love to know how it all fits together. For example, I use a Hobbywing Xerun-v10-13.5t brushless motor (30401103) with 1s 3.7v lipo battery, 8000mah, 100c. The ESC is a Hobbywing XR10 Pro 1s 120a. Typical runtimes are 4-6 minutes at full throttle. I have no idea how to gear it optimally, or get the best performance out of the motor. No idea either why the ESC needs to be 120a. I do have a Motolyser motor tester which gives me Kv, rpm, sensor deviation, magnet asymmetry and amps per phase. However I don't really know how to make the most of this information. Could you help?

Love the shirt. Lol Thank you

John Holmes, you've got my interest in building my own motors. I just can't shake it off my head now, but I can't find the parts! Have you ever thought about selling non assembled motors?

Merry Christmas to you and your Family, John!! 🎅🎄 I really enjoy these Refreshers. I've been in Model Railroading for at least 10 years longer than I've been in RC (or 47 Years!) . Maybe it's because Model Railroading originated in Europe.... But the Motors are always classified as "Poles". Oddly, the number of Turns are rarely mentioned! 😱 Obviously in RC, Turns are the Main selling point. Now, one point that you barely skimmed over, your top Brushed Motors, 3 and 5 Slot, BOTH have *Skewed Armatures,* which has quite an advantage all their own..... Back to Model Railroading, when I started (when NIXON was still in Office!!!) 😆😊, the majority of Motors had 3 Poles (Slots). Also had weak Iron Magnets and Bronze Bushings. They started from a stop like a Model T with a fouled Plug!! By the 80's, 5 Slot became the Norm. Starts got smoother, but still not great. In the 90's, we finally got 5 Pole, Skewed Armature Motors, Rare-Earth Magnets, and full Bearings. Where the best we could do for minimum Speed was 5 to 20 SMPH (Scale Miles per Hour), in the 70's.... We now have smooth as Silk starts, with a minimum sustained speed of 0.3 SMPH or BETTER!!!! MOST of that was attributed to the Skewed Armature! German Company, Märklin, was fitting *7 Slot, Skewed Armature Motors,* and the performance was breath taking!! Maybe most RC Guys don't need to know, but Skewed Armatures are considerably smoother at extremely slow speeds. Why? Because of the placement of the individual Armature Plates, there's virtually NO gap between each Slot, as the Armature spins. Due to that, any slight cogging between Comm pulses, is almost completely eliminated!! 😎👍👍 Think of the Low Speed Resolution, if all your Hand Wounds has Skewed Armatures... The Performance would be World Leading in the RC Biz!!! Carmine 💥 ⛽

Thanks for the video JRH. anyone noticed the gold plated magnets in the puller motor? Plus @ 6:58 you get to see the built in/ fixed timing ring. That's something I was really looking forward to seeing. So I didn't have to teardown my new puller motors right away. If you ever have time a video on timing a puller motor would be awesome. I understand how to time a 540 motor with 6 degrees of timing. However I'm under the impression timing of a puller motor is done off of lowest amp draw. Not just simply figuring out forward rotation and turning end bell opposite direction 6°. Or can I time my puller 500's with 6 degrees of timing without any bad effects? Again thanks for taking the time a making these videos.

It's 2022, most people have moved to brushless.. I still use a Crawlmaster Pro has nothing seems to have the same feel as a quality handwound brushed motor from John Holmes.

got the info in your tutorial there is no issue with reversing wires to terminals- I'm guessing No damage will occur if I accidently hook up both to Neg or both to Pos- Kyosho I have has like 4 terminals.

I dig the dab tool 😂

I love the enthusiasm in the beginning!!! lmao

Talk about what different turns and what effect that has on performance

Merry Christmas. Fantastic video. Are the Holmes Hobbies motors on Asiatees genuine Holmes Hobbies motors ? I'm in England if you could suggest the best place to buy a CrawlMaster Pro?

G'day have u a vid on setting up the motor i have upgrade from a standard 540 21t to a 550 27t for a 1/10 drifter it doesn't seem right could my motor be too hard up on maybe I do need to over gear a little to get the setup im trying to achive sorry for the long comment

Nice information. Can you do a comparission against a trailsmaster pro and a brood apocalypse...thanks

Is there a video which explains the relation to single, double and even triple wound motors in RPM and torque ?

It's Holmes Hobbies channel... We need some advertising xD! I'd like to see video about your motors, whole product line - pros/cons/purpose/features.

Cool shirt

Yes, John, I have more questions. My father built field & armature-winding machines for Black & Decker back in the day, so I'm no stranger to electric motors. I'm curious about the number of turns - specifically, is the number in reference to the turns of wire on the field coils or the armature? Also, is it true that wire of variable thickness is used, and if so, why? One other thing; how can there be a '.5' to any number of turns? If you can address any of these curiosities I would be most appreciative. -AL

Do I have to lathe the motor when I do a rebuild

Always love the tech stuff John. Was the bigger rotors the 550-can ones? I'm your big Revolver fan...I think I have 8 or 9 of those torque beast. What kind of magnets do the Revolver's have? I know they will try and bite you when putting them back together. Merry Christmas buddy. Tom(Tommad on facebook).

Wahoooo!.Like that shirt didn't give you some attitude. Didn't hurt to have a refresher on the brushed side of motors, still have a couple of them left..lol, and this from a guy that said he didn't see a need for brushless. So a question comes to mind; with more torque will it drain the battery faster? Keeping all else the same or if using a rig that has more torque than necessary could have a lower drain rate than the 5 slot? Happy Holiday's Mr. Holmes, sure that you will be snatching a few more dollars from my wallet this next year.

THANK YOU JOHN HOLMES! Thanks to this vid, I was able to re-time my "Un-rebuildable" stock axial motor for another rig! Was able to correct the issue with reverse being faster than forwards!

how can i use the screw connections on the motor?

Does a skewed rotor run more efficiently in a particular direction?

What would be a good sensored waterproof speed control for a Leopard 3658 2200kv 4 pole motor. Off road, about 13 to 14 pound vehicle.

There are ways to do all sorts of differeng variable especially the way you wrap the wire espcially. If youre wrapping those armature poles with more than a single wire size simultaneouly 2 at a time. Or say first one then the next . or say one for a while then so l diers onto a different othere size ??? And Skewing the armature to eliminte the cogging effect .... Will be explaining it all as soon az you ask.

What is the most popular brushed motor

whats the difference between...say a 19t single and a 19t double or triple?

Holy crap your name is john Holmes?? Interesting

Does john smoke? or is he oblivious to the fact that hes using a glass hot knife as a presentation pointer? hahah

How about the turns? It has been 25 years since my last brushed motor..😁

Hey know it all... Its not a Rotor... Its an Armature ...... Oh also did you know that when you wrap the Armature stacks , 0n a 3 pole like this , I encourage you to perform it in typical 5 five pole or stack Winding (2)two stacks at a time until all stacks have been done.. Ill explain more as I go.. But Ill show you just contact me.

I bet you still have this hat ? LOL

your showing me rotors that arent wrapped in copper that throws me off

wheres the part where he explains what turns are and how it effects performance. no one wants to sit through a 15 min video for 30 seconds of info. Edit: hard to imagine, from the bit i know about motors, that the amount of copper (number of turns) doesnt effect torque. the way he explaining it he made it sound like the only way to get more torque is to either buy a larger diameter motor or a longer motor

hey big expert. why dont you or at least talk about skewing the armature for reduction of the cogging effect .... cmon show us what you know and tell us about it and why.??? talk about those armatures??? plus why using 2 wire sizes at the same time when rewinding ... you know augment the wire size by using the guage desired then by augmenting slightly using a very very thin guage wire added to and with the initial guage you are using. ie. say a 24 guage wire coupled with say a 35 guage second wire to augment winding both wires around the armature poles simultaneously , plus skewing the armature poles at the same time to mitigate cogging . why ??? also why not wind those 3 pole armatures like a 5 pole wrapping 2 poles simultaneously thus keeping the wire closer in to the shaft rather than out on each pole causing more drag.?? why??? seems like you might be concealing this knowledge from your viewers and potential customers. why?? cmon share the real secrets. like why not wrap the 5 pole armature like a 3 pole . each pole wound individually rather than 2 poles wooven together as is usual. you know winding each pole helps eliminate the heat problem . why dont you talk about timing advance by turning or rotating the Comutator ?? why?? seems some folks might need to know this knowledge while you sell them something they could have done themselves to enhance the performance of their motors... seems kinda strange to many of us out here whom know better??? John Holmes?? how ironic. what a name indeed. if you get the drift. whos screwing what??
