Traxxas TRX4M Motor UPGRADES: NEW Injora Brushed Motors for BIG PERFORMANCE GAINS!

In this video I test and review the new brushed motor upgrades for the Traxxas TRX4M just released by Injora. There are two options, a 55T and a 48T PRO. Both of these motors are upgrades to the stock motor in terms of speed and torque with the PRO motor offering up more of each plus an enhanced drag brake. These are available now on Amazon through the links below, or directly from Injora!

I bought the Holmes motors already a few weeks ago but comparing to the holmes is a good question

[@paulmartinez4994]

48t crawler gear vs stock motor and crawler gear would of been what i wanted to see. Perfect video overall.

[@Sparroh]

I can’t thank you enough, comprehensive, positive, thorough and fun. These videos have helped so much.

[@greggrube2948]

You're pick of the motors seem to be spot on, I thought the 48t was the way to go also. Awesome video Adam 👍😁

[@CapeCrawlers]

Thanks! That 48t made the choice easy. Great little motor

[@bolt.22]

Injora also just released stainless steel low range transmission gears for the trx4m, good time to get both!

[@CapeCrawlers]

Yes!! I got two sets of the gears on order. So pumped

[@tundrasr5709]

I'm more into performance than scale looks. I already had the crawler transmission when I watched your Bettle video, which prompted me to run my defender with no body. Huge improvement, so I ordered the Bettle chassis. After watching this video I ordered the pro motor. I would have liked to see the Bettle in that comparison. Thanks for another great video.

[@CapeCrawlers]

Thanks for watching! I like the bettle setup a lot. I haven't tried these motors in it, but the next time I tear it apart I will give it a go.

Great video and comparison, my friend. I always enjoy your videos and how comprehensive you are with all the technical aspects. I just installed the 47T purple can into my TRX4M bronco with the crawler gears and I love the added performance of the drag brake, additional speed and the massive increase in torque. Highly recommend either of the motor upgrades for the price to anyone into the hobby. Again, great video and keep the content coming, my friend.

[@CapeCrawlers]

Thanks Mike! That purple motor and crawler gear combo is excellent!

[@drivingwiththeboyz4552]

just orderd the purple motor after installing the crawler gears lol

[@chrish9502]

Does the new motor torque negate the crawler gears or do you still get that slow speed control?

[@mikecraig426]

@chrish9502 The torque of the motor doesn't negate the low speed control. The power delivery is very smooth and easy to control.

[@chrish9502]

Thank you for this review and comparison! I had the pro motor already in my Defender and I am going to install the crawler gears for better crawling performance! Thanks again!

[@Iskremfrpupy]

I think the Injora 48T is actually a little harder to control crawling than the stock motor because of the increased wheel speed available. I have crawl gears in both.

[@paolo8768]

It's the perfect combo in my opinion.

[@anmic3590]

Hi! Which ones of the low range gears will work perfectly for the Defender? I saw on amazon that there are 4 options. 40.3, 9.7, 16.6 and 24.4. Sorry, but I’m new to this and I’m trying to build a Defender from scratch, with injora parts. Also, may I ask what servo and esc will be the best? Maybe waterproof too. As for the axles, I’m thinking about the diamond ones (4M-92SRFR), but still not sure. I will take their universal chassis with battery plate and skid plate, the shafts (4M-50BK) and links (‎4M-20) also from injora, the 53 shocks. Any advice will help me a lot. Thank you so much!

[@alexandertaggart4369]

Hell yeah thanks again Adam I just ordered the pro right now!! I've been waiting for a good motor to come out for these things so I don't have to go and put a furitek system in mine..... For now lol

[@CapeCrawlers]

Right on! These motors and the crawl gears rival the brushless system, at least at low speeds. Bargain crawling gains right here.

[@jtatkinson6825]

Thanks for doing this comparison. I've been on the fence about buying the purple motor and pulled the trigger after watching this. Bought the metal crawler gears as well.

[@CapeCrawlers]

I think you’ll love the combo!

I'm definitely going to have to swap out my 87t Holmes hobbies motor. Especially since im waiting for my underdrive gears to arrive for the rear axle.

[@cbix86]

48t looks perfect, such a shame they aren’t waterproof though 🙈 I’ve tried the 66t Holmes and it still lacks punch and high speed!

[@URsooomad8613]

Yea not being Waterproof really ruined them, Holmes Hobbies is definitely the way to go

[@petejones6827]

why would it not be waterproof? cause the board? you can just paint it with a waterproofing agent. all electric can motors can be submerged hell most people put them underwater and run them to break them in and wash out the bits from the brushes breaking in. if i remember right i did that to try it out on my fms k10 which i put the injora scx24 motor on and i ran it for a couple mins in a cup of water before i put it on and its still goin strong that was a couple years ago now

[@xiuhdj]

great work putting both motors to the test! I think I need a bronco to join the defender and have a go fast rig and a climb hard rig

[@CrivRex]

A great part two for this video would be diff gears with these* motor combinations. Looking at alternatives right now to get my speed back up.

[@jimkrug2586]

Loved the motor/gear comparisons. I currently run a Holmes Hobbies 66T/low range gear combo in all three of my TRX4M's. I'm very happy with that combo but would still like just a bit more wheel speed. I think I may have found just what I'm looking for!! Thanks.

[@CapeCrawlers]

I haven't tried the Holmes motors, but these certainly helped with wheel speed!

[@S5UPERCHARGED]

You could just run 3s. Voltage = rpm

48T motor ordered, I wonder what the 48 is like with the speed gears in the overlander🤔

[@BellaT-nu4vv]

the problem is the low level modulation of the esc with that thing. the best solution is still furitek

Hello Adam! The video I’ve been browsing for ages on the lookout for! Finally did after resorting tot he cape crawlers channel :) I only have one question, can you explain me if it’s worth it for me to go brushless?

[@ricklebel6298]

So have you ever paired this motor with the esc/receiver from a scx24?

[@chaipani7189]

would you choose the 48t pro with crawler gears. or the Traxxas brushless ?

[@boiledtea479]

ive got the purple one for the scx 24 nd i really like it. waaay more low speed control and with a lowwer gear ratio it would be waaaay smoother. defo a future projekt

[@wingnutbert9685]

@@CapeCrawlers I was just thinking to ask if this 180 size fits in an scx24. So just to be clear, you are talking about this pro size, not the smaller 050 scx24 size pro?

[@byarfy]

Hi Adam. Stok motor + low gear or injora 48T + low gear for crawling at low speed and low speed control? I dont care top speed, i like realism and low speed control. Thanks for all awesome videos.

[@Broomstickzzz]

Injora pro or big block motor with a crawler gears. Would love your advice. Thank you for the awesome videos and channel

[@CapeCrawlers]

I have not tried the big block on the Traxxas, but I have in the SCX24. It's a beast; very broad power with lots of top end. I can imagine you would get similar low speed torque to Injora Pro, but the big block would likely walk away from it at high speeds. I may have to try the big block myself to compare them!

[@Broomstickzzz]

@@CapeCrawlers awesome thank you for the help!

[@GeorgeLoch]

I just added the 48t motor and craw;er gears to my Bronco and found that it works great but is a lot louder. Did you see that change in yours?

What esc mode were you running in this video?

[@kendietz355]

I'm happy about these motors.

[@rustlervxl09]

Have you ever tried the 24.4:1 gears? Wondering if that would be the best combination of the 48t motor to get similar speed to stock gears with better control for crawling. Great videos!

[@Atmotom1]

Do you have a video of all the upgrades you have on this rig? Like other than the motor and transmission obviously lol this video is greatly helpful tho

[@stefan-norge]

Great comparison, Adam. Everything one need to know on point 👍

Glad it was helpful!

[@Atlas_FPV]

The 55T looked smoother for crawling, is that just how it seems or is it smoother at low speed?

[@Atmotom1]

I thought that as well and wanted to know the same thing. I think I kinda liked the way the 55t looked crawling more. Gonna have to watch both the runs again a couple more times I think lol but I might be ordering the 55

[@keith6360]

What a great comparison! Thank you for this. Im wondering how fast does it drain the battery with the new motor? I imagine it drains it much faster?

Thanks for watching! I have not noticed a significant drop in battery life. My son and I both get multiple sessions out of the trucks without the battery dying

[@ericcastaneda8797]

[@MRSOMEBODYRC]

I am curious if this motor will work on my wpl c24, stock gearing. I did purchase the injora 180 motor and will attempt to install and see what happens. There is no videos about such upgrade on WPL. might need to change polarities due to being revered rotation.

[@RonBernardino]

Neat trail. Space out some rocks to make it look like real trail.

[@j2themen07]

What Brushed Hobbywing ESC would you rock with the pro motor and crawl gears, plus adding the 9% OD and 9% UD for the front and rear, any thoughts? Thanks in advance.. love your videos.

After some weight on the defender, going over things and turning causes it not move anymore until the wheels are straight. Do I need a new motor? or ESC?

[@CapeCrawlers]

The closest I've seen to a reduction gearbox is the Hot racing unit, but that only overdrives the front and leaves the rear stock. I would love to see someone put some serious R&D into the gearbox of the scx24.

@@CapeCrawlers Hopefully the success of FCX and now Traxxas with spur Axial to get off their backsides and get with the program. I think they kinda blew it with the AX, from the looks of it.
