Got a scx10 with a 32p 56t with a 10t pinion. Got underdrive gears with gripfab arb lockers in both front and rear axles. Looking to have ultimate crawling capability as my number 1 priority. I don't care about top speed, but I would like to have some oomph for those loose dirt hill climbs. I was looking at the crawlmaster pro 20t (or a 18t if I could get John to build it for me) or do I get the puller pro stubby 2200kv? Will the brushless set up have down low start up like a brushed motor? Or as a wild card (my friend has this sitting around) a tekin 40t pro with fxr? (My Holmes motors will be bought with matching Holmes esc) please guide me towards the right decision. Thanks!

Which motor should I run for my scx10

My brushless experience is very limited, but I'm VERY happy with how my HH Trailmaster Pro 3500kv crawls and the power and speed is incredible as well. The puller is a 4 pole motor and should be even better, combined with it's lower kv.
I made a short video comparing my 30t TM pro bushed motor with my brushless setup with the same 17/80 pinion/spur ratio, as I wished there were more of these direct comparison videos online when I was trying to make the decision. Most people will tell you if your one and only concern is crawling then brushed will be better, and I don't disagree, but brushless is a whole new level of fun.

Tekin or Holmes are both great options, but I would stay at 35 turn or more motor if you go brushed, the lower turn motors don't last long even crawling. If you run 3s lipo, the Traxxas 550 can 21 turn motor is a great option paired with Tekin FXR or Holmes waterproof BXL esc.
Lower turn then 35t?? I wanted the 20t crawlmaster (if I can get a custom 18t crawlmaster pro so it'll be a 40t equivalent I'm assuming. I'd go that route), isn't that equivalent to a 45t? I had a tekin roc412 3100kv before. And wouldn't mind going brushless (if I go brushless I wanted the Holmes hobbies 540 stubby 2200kv) but I have no interest in wheel speed for this build. Just want the motor that's gonna give me the best low speed control with nice hits of torque to get up and over things.
Yes, motors with less than 20 turns (except for Traxxas 550 Titan 21 turn) don't last more than couple months in my experience. Power equivalent, but shorter life, they tend to go through brushes and commutators quickly, needing rebuilt every couple months or less. Then you know ROC412, HH is good brushless too. What batteries are you planning to run?
The Crawlmaster in 20t would be about like a 40t in a regular motor, and thus would last a long time. Natedog is correct about faster motors wearing out sooner. 35t is a nice balance, or 16t in the CrawlMaster line. CrawlMaster motors wear better than equal speed TorqueMaster counterparts, because the 5 slot arm produces smoother commutation with less arcing.
I have one 18 turn armature here that I made a while back as a custom, and the customer changed his mind. If you purchase a 20t and put a note in the order that you want the 18t arm that is hiding in the "random" arm section, we will build it as 18t.
The Puller Pro won't quite have the smooth startup of a CrawlMaster, nothing does except the 5 slot Puller brushed motors. But it is dang close and you could always use a little more KV or voltage and then gear down to get that startup butter smooth.

Pretty good comparison of the two. Did you find a preference for the brushed or brushless? It's not a fully fair comparison since the BL motor has a ton more wheelspeed, but it does showcase the wide range of control possible with a properly designed motor and quality ESC. Folks don't believe the TrailMaster Pro is two pole sometimes, it is just so much smoother than other two poles sold as crawler motors.
So what would the 18t motor be equivalent to for a 3 slot motor?

I'm definitely in the brushless camp now. My first trip out I didn't have my drag brake set high enough so I was struggling a bit, that and I had to get a bit creative with the curves so I could quickly and smoothly transition from forward to reverse to keep the rig from rolling where I didn't want it to, just all a matter of taking to time to tweak settings. If anything I swear it crawls even better than my 30t TM Pro.
35ish turn. 18 turn isn't a standard offering because 20 and 16 can have better copper fill, the one we made was between regular and X heavy fill.

I've got one of each of most of your motors now (Crawlmaster Pro 13T & 16T, Torquemaster Pro 35T, Team Puller 500 Crawl 13T, a couple of the old Trailmaster BL blems that you cleared out a while back, a couple of Revolvers, and new Puller Pro BL Stubby 3300). There are some personality differences, to be sure, but all of them are terrific. I am really impressed with the new Puller Pro stubby. Hard to believe it's brushless, and that's coming from someone with multiple ROC 412 3100s. Your advice to volt up and gear down regardless of the motor is spot on. Add in an exponential throttle setting on the ESC or radio, and all of them are super smooth on the low end with plenty of punch when you need it (or just want a giggle). I can honestly say that, regardless of which of them I'm running, I never find myself wishing for anything other than what I have. To the OP, you really can't go wrong with any of them.

Thank you for the kind words sir. I try to design everything as good product for off road use, with each having unique purpose and cost for a full range of choices. You certainly have a good sampling of the same stuff I like to drive 8)
However, I feel the Revolver stubby and Puller Pro stubby overlap too much, with the Puller edging out overall utility because of the wider RPM range and snappier response (lower rotor moment of inertia) . But, if the Revolver 540 is compared to the Puller Pro Stubby, which is more fair when considering size, the outrunner is an absolute beast and will produce far more torque than tires can hook down.
Your thoughts?

The Puller Pro is where it is at. Coming from some of the machine wound HH motors to the Puller Pro 3500kv isn't a fair comparison, but this motor is by and far the best I've used. Low speed I couldnt discern a difference between it and a brushed motor in my tests last night. High speed, well, I may need to replace some of the carpet in my house now:lmao::shock: Quality is bar none. I've always been a fan of HH products and this only reaffirms my choice. Couple that with the on forum support John gives it's a win win. When it came time to go brushless it was a no brainer whos motors to pick. My only complaint is it didn't come with stickers to plaster my rig with!:ror:
No stickers! maybe you got it at a hobby shop or another retailer? We should start including them in all the product boxes to avoid this mistake!

RPP, had to take advantage of the 15% off they had the other weekend!:ror: It probably goes fast enough to peel them right off though:lmao:
Thanks for another quality product!"thumbsup"

If you have the cash get the stubby 3300 kv waterproof. It will be everything you will need in a motor.

This is most likely the motor going in my C1, already got the S300's to withstand the abuse:lmao:

I put the full size Revolvers into my heaviest rigs (a Beast and a D110), and the torque is insane, esp when combined with the low speed resolution and top end on 3s. Maybe enough to tow the minivan, lol.
I could see the potential for overlap, but please keep the Revolvers around (even if only for limited runs a couple of times a year). I have the Puller Pro stubby in a China Jeep Skeleton, so it's not a direct comparison to the full-size Revolvers in the heavy rigs. It's not hard to imagine that the performance of the Revolver stubby would be very similar in a typical 6-8 lb rig and perhaps eclipsed by the versatility of the Puller. I can say that after my initial testing of the Puller stubby, I don't find myself craving a Revolver stubby in the lighter rig. But I have a hard time imagining anything else working as well in my porkers as the full-sized Revolvers do, so I sure as heck hope that you'll have more full sized Revolvers when I build my next 10+ lb rig.

Considering HH esc and maybe brushless motor for my Ascender, how would this motor be on 2s?

Lemme plug one of my 2s packs in tonight and play around, I cant imagine it's going to be terrible. I generally run 3s packs though.
I'll be going with a BLE in my C1 build, probably with a Stubby Puller.
