I feel like someone somewhere in the comments has already mentioned this, but since I scrolled and didn't see it I'll mention it again for anyone else trying this.

The reverse rotation on the Titan 12T motor is actually partially why it's getting so hot in this video. The original motor that was labeled specifically has inverted fan blades. Since the Titan motors have internal fans, the reverse direction motor has the correct fan rotation to help cool the motor. When you run the standard Titan 12T backwards the fan is running the wrong direction, so it's not properly cooling the motor. It's not a huge deal, but the increase in temperature will be quite noticeable.

This used to be one of my go-to upgrades when Axial first released the wraith years ago. It was honestly my secret weapon at the local meets (I didn’t actually keep it a secret, I think that’s silly). Got lots of “brushless?! Must be sensored right?”… many jaws dropped upon hearing it’s a $15 drop-in upgrade they can snag a block away at HobbyTown.

That said, i had stepped away from the hobby for years until just this year when I decided to dive back in. Exactly as expected, I went from “I’ll maybe get a micro to mess with and see how it goes… nothing too crazy”.. to now owning 4 different scx24’s, two are Furitek head to toe, fully upgraded, one is stock and one is a Furitek Rampart conversion, an element enduro gatekeeper, a Losi Hammer Rey, a couple mini-z’s, an FCX24, and I just ordered a TRX-4 K5 blazer last night…

All of that to say, it’s good to see this upgrade is still viable!

No prep drag racing in a TRX4!! Now there's an idea!! 🤣👍🏻

[ThePhotographerMax]

Honestly, you could probably turn down the throttle response from 100% to 50% (on your transmitter if you have the option) and it would be excellent for crawling! Just an idea!

[Nardo_stpierre]

I’m running 2S, 12T with a heat sink. & I love it. I can lock up the difs and crawl in low gear or unlock my difs hit trails in high gear. Lots of fun.

[Riverdale__Murrrland]

A fast crawler is actually a great idea, that’s my specialty favorite! Nothing and I mean nothing compares to Crawlers scale features and only if it was fast. I love bashers, but they aren’t realistic looking. So a fast TRX4 F-150 High trail edition or a 79 K10 or a k5 Blazer High trail edition with a minimum 30mph would be a hits

Thanks for the advice Mark. I had a 12T in my toolbox. I had a whole new TRX imo. The crossing of the terminals was the best RC advice I’ve ever been given that worked perfectly. I didn’t want to reverse the transmitter. Problem solved!

[oscarmike]

I don't know what's up with your videos, but every time you upload new vids its just draws me in. your vid are so entertaining. thanks for a great video.

[homergonzalez]

When I had mine I upgraded to a 2 speed transmission and you will get the speed you are looking for and still be able to trail it no problem

[bobtierney]

The 12 turn is a zero degree advance motor so it runs in either direction just fine.

[hartleyglenn]

I’ve run some huge brushless motors on my TRX4 and my sons the portal gears take the most abuse when jumping

[tomdewitt]

I've been doing this for a while, the reverse rotation 12T from a 16.8 E-Maxx pops right in. Same color wires and "Titan 12T" facing up. if you use a traditional rotation 12T just flip the motor over a have the red wire on top, the sticker will be facing up and it won't look like you have some Frankenstein motor in there

[derricksazrc]

Wow hands down that is a lot of bang for your buck. For some reason I thought the TRX-4 had the 12 turn in it till I built a slash last weekend and felt the motor in my hand like you expressed it’s hefty.

[michaeldorich]

Good video. It gives some drivers another choice with a low cost. I would like to see a video of the boys working their cars.

[jarroddurham]

My trx4 crawler kit has a castle sidewinder4 esc and 3200kv brushless motor. It screams and crawls

[martialsix]

You just told me why i have gone through 3 motors on my traxxas raptor. Never knew you weren't supposed to use 3s on the 12 turn motors

[SliverRc]

My Daughter Runs the Trx4 Sport 12T Titan Motor with 11tooth pinion and hobby wing 1080esc. the 3s works great.

[rmarkley]

Great Vid, Melissa driving had me smiling, you guys rock!

[ragsixracing]

Swapping the wires on a 12t, it will have advanced timing in reverse. Faster in rev.That is why the 21 turn is the reverse version in the trx4-6 trucks. The 12 t may run cooler since it has retarded timing in rev(May last longer). Holmes hobbies has an 8t 5 slot that will outlast, outperform, that titan and it is a zero° timing motor, so you can run it in a slash, or a trx4, it won't matter. It also comes with bearings as opposed to the titan, and costs 2$ less.

These motors last on 4s too. It's a no brainer Mark.

That is if your really looking to bash the trx4... I would love to see a brushed motor shootout for the trx4.

I just bought my first crawler 3 weeks ago, and I really enjoy them turns out
