Holmes Hobbies TORQUEMASTER MINI - The Best Brushed Motor Upgrade For The TRX4M?! Run & Review!

In this video I install and review the Holmes Hobbies Torquemaster mini 180 66t brushed motor upgrade for the Traxxas TRX4M. The TRX4M Bronco is currently running the Injora 48T brushed motor, so I was able to provide some direct comparisons among these two excellent motors. Watch on to see how they perform!

I have spent the last week watching all of your TRX4M videos before I finally bought my own. I want to thank you for putting together such informative content that really makes sense and helps anyone understand the TRX4M platform. I will defiantly buy this motor when I eventually upgrade from the stock one as soon as I get my TRX4M in. Once again thanks for your amazing work on your channel. I can't wait to see what you do next on the TRX4M platform.

[@706Rocks]

Thinking I’m going to go this route for my sons truck which is more of a budget friendly build. Great video, thank you.

[@darkcloud4368]

Really impressed with the slow speed on this motor. Almost like brushless for somebody on a budget.

[@CapeCrawlers]

Absolutely!

[@juniorwest5706]

Holmes Hobbies , makes some fantastic products, I run the 550 crawl master in my RedCat 😎👍

[@rcjoe406]

That's how my 66t holmes hobby is for my scx24 sooo smooth...maybe I'll put this in my bronco and move the 48t pro over to the defender

[@joseaponte2829]

Hey Adam. Thanks for this video. I like to upgrade my motor on my white Bronco, i never knew Holmes Hobbies motor was that good. I seen it on Amazon just glancing at it never checked out until i watched your video. I was goin for the injora 48t pro. But i see why the 66t is a great crawler motor. I appreciate the video i like watching them, thanks 👍🏼

[@Matt-it8jh]

I run the trail master sport 540 in my redcat. Tons of torque work really well with my portals. Holmes definitely know how to make a good motor.

[@GD-um8fv]

I really like the 87t Holmes motor. However on downhill sections the drag brake the is reduced but that low end throttle response is awesome. I agree $16 for this motor is a great upgrade for the TRX4M

[@MikeRCWorld]

New motor is cool, nice upgrade. Cool place for crawling, enjoyable video 👌🤠

[@johnny240]

"lets not use that one" 😂 that killed me

[@CapeCrawlers]

😂😂

[@Atlas_FPV]

This looks really nice, think I'm gonna get one. The Injora 48T seemed quite jumpy in the videos and I'm all about that slow control crawl, I dont really care about the top speed

[@CapeCrawlers]

It’s a very smooth motor. I’m really happy with it

[@BigMountainCustoms]

Uh, no Adam....the higher the turns, the SLOWER the motor. That's why the basher guys use 12 and 13T motors and the crawler guys us significantly higher turn motors. The higher the turn count the slower the overall speed but also the higher the torque rating.

[@80SWoods]

I may have heard differently but I didn’t hear him say that higher turns was faster? He said that the 66 was faster than the stock 88 turn which is true.

[@CapeCrawlers]

I thought I said lower turn was faster. If not, that’s my mistake

[@_alienx_p]

You said twice that higher turns are slower and more torque and that lower turns are faster

[@gibsonlife573]

Good job man mixing it up right there that was a good one I like it

[@JeepinMaxx]

Thanks for the video! I'm curious how you like those new tires - I just put a set of those Injora 58mm All Terrains on my TRX4M & FXC24 K5 and found them to be the perfect size and nice and soft with the supplied foams

[@CapeCrawlers]

I love the tires! They hooked up incredibly well on the course. I typically like bigger tires, but these seem to look, and work extremely well on the Bronco.

[@greggrube2948]

Adam, does somebody make the stock metal transmission gears for the trx4-m? Awesome video!

[@christianlombardo8566]

Injora

[@christianlombardo8566]

At least the crawler gears but I think Traxxas has metal stock gears

[@greggrube2948]

@@christianlombardo8566 thx for the info!

[@CapeCrawlers]

Yes, Meus racing makes stock ratio steel gears

[@gibsonlife573]

Seems like a high start up like maybe if you put a smaller tooth pinion on the injora would be so much better

[@bb4l881]

I've just bought the trx-4m defender. I've got hundreds of £'s worth of upgrades in the post, as well as a furitek brushless setup. I just wouldn't/couldn't waste my money on brushed motors.

[@pickneyjoshua9295]

Dude. A furitek setup is like $150 and that’s NOT including the new radio and a receiver needed. I don’t think most people playing with 1/18 scale crawlers are looking spend that kind of money. Meanwhile, this motor is $16…

[@SysTek2000]

Hey, Adam! Great video as always. I'm having some trouble if you don't mind helping me out. I'm noticing that both of my TRX4ms have an annoying amount of slack/play in the drivetrain. I have the upgraded drive shafts and pinion gears from Traxxas if that makes any difference. If the truck is on flat ground you can role it back and forth almost 1/4" to 1/2" which gets really annoying on obstacles. Any ideas on fixes?

[@seniorxj2931]

Do you think the results will be the same on an SCX24? I have the 50T Pro Injora and am looking for a smoother slow crawl!

[@BigMountainCustoms]

The higher the turn number, the slower the motor. So, in theory, they also give you a smoother slow crawl. However, nothing will come close to a brushless set up. However, I never see anyone mentioning that adding magnets on the OUTSIDE of the can will also slow it down and boost the torque numbers. Back in the day, when all these custom motor builders didn't exist and we couldn't alter motor timing, we used to add rare earth magnets to the outside of the motor can (the stock magnets will pull them into alignment.) And, like I said, the extra magnets help slow down the motor and boost torque. Effectively just like re-timing today's modern motors that allow timing adjustments. We also used to piggy-back op-amps onto the ones inside the speed controller.. Adding an Op-Amp on top of the stock ones (soldered to the pins on the stock one) provides more Amps to the motor. However it doesn't slow it down...it actually speeds it up AND boosts torque numbers....but, modern esc's don't employ Op-Amps like they did in the past. I'm not talking about the old school mechanical, servo driven esc's. The esc's I'm talking about were the original "solid state" pre-modern esc's we have today....however, I have soldered MOSFET's across the terminals of the motor (where youd usually find a ceramic capacitor) and it significantly boosted power and torque without speeding up the motor... All just ideas that we used to use...if you choose to try any of these, don't quote me on it....use under your own responsibility. If it were me, and I wanted to try any or all of these I'd most likely try them on old pieces that were destined for the trash anyway. Ultimately, stock is boring. Just have fun! And, always always always, make it custom... and share ideas.... -Big Mountain Customs-

[@crawlerballer]

I already installed the low gear transmission, would adding this motor be overkill? Kinda curious to see, either way! hahaha Anyhoo- I'm glad you made this vid cause I just got this motor and wasn't sure about it!

[@CapeCrawlers]

For me it’s perfect with the low gears. It’s very slow though.

[@danh2608]

Great video. What front bumper do you have on orange bronco? I think im goin to get the holms motor but the other one for the stock gearing. I like the speed for tails.

[@CapeCrawlers]

Thanks! The bumper is the Injora tubular steel bumper. amzn.to/3tep65J

[@Stupidthingsrc]

Maybe I should get some trx4m’s and a couple hundred dollars in parts to give me something to do with my ankle being the way it is😅

[@JUSTHAVEFUNRC]

Sounds like a good plan.

[@RCCrawlerz209]

That's exactly what I did. Lol got me a TRX4M & spent $500 on it, something my father was disappointed on....🤦🏼‍♂️😅 My rig right? Can do what I want. Lol

[@JUSTHAVEFUNRC]

@@RCCrawlerz209 I’ve spent an unhealthy amount on tiny trucks. My folks still think I’m in the $400 all in range…

[@Stupidthingsrc]

My parents aren’t to thrilled about how much I have in my little trucks

[@laxm8162]

Awesome review! Do you have any idea how the holmes hobbies motor would perform with stock gears? I expect it to be slightly faster (maybe close to what the injora 48T did with crawl gears!).

[@CapeCrawlers]

Thanks! It would be fast. Much faster than the 48t and noticeably faster than the stock motor I imagine.

[@teachemc]

Like your work and my trx4m what about the 87t stock Moter for low-speed crawling?

[@CapeCrawlers]

I ran the stock 87t on crawler gears for a while when the M first came out. It did great!

[@RCCrawlerz209]

Question: Will this motor work, when one has the portal axles on the M? Like, you can switch the wires around, if need be??

[@CapeCrawlers]

Yes, you got it

[@RCCrawlerz209]

1. Update: I may have my dad help put screw holes into the bumper mount (holes that's not being used) to help my bumper stay in place when I clip/unclip the body on/off. 2. Who knew that Holmes Hobbies did motors for these little guys, cuz I guess I only knew they did motors for the 10 scale rigs. Haha 🤦🏼‍♂️

[@BigMountainCustoms]

Yeah, John started doing 24 stuff when it became obvious these small scale Crawlers weren't going anywhere anytime soon....lol....so, we've had HH motors available to us for a while but because it wasn't advertised nobody knows....well, very few people know...
