E-Revo dewalt conversion

I recently bought the brushed E-Revo and I love it but I've been reading about people blowing up the factory titans so I'm looking into a replacement motor. I'm not expecting brushless speed but a little more would be nice and although I've seen a lot of people using 14V dewalt motors I haven't found anyone doing it with the 18V motor. Since I have several of these already, I'm thinking that might be an option for me. Anybody have any advice?

I used the 12v on mine. Worked very well and the motor was only $28 brand new. I am pretty sure the 12v and 14v motors are the same though. There is a good write up on the dewalt conversion over on the (dare i say it) traxxas forum.

Thanks Josh, I did see a few threads about the 14V but I'm thinking more along the lines of the 18V. Will that produce more speed/ torque or just suck batteries? Also wondering if the stock speed control can handle it.

I dont know if using the 18v motor will gain anything at all, but likely not. I think using the 12v motor and pushing 18 volts through it by running 5s lipo would be your best bet because i think overvolting the 12v would produce more rpms than the other motor on 18v. I only ran 4s on mine but i know a few people were running 5s with the stock speed control with good results and as far as i know havent burnt a dewalt motor up yet

From what I have seen and read the EVX-2 handles the dewault motor fine on 4s.

I always wanted to builld a brushed big motor revo or maxx for crazy water bashing in rivers and snow and stuff.

I guess the only thing really holding me back is th EVX-2 not having LVC.

Post up some pictures will yah.

Just get a Holmes Hobbies ESC with the waterproof option...

Here is mine.

@Reno- Which Dewalt are we talking? 12,14, or 18V?
@Arct- My main goal is to keep the price down so I wanna use as much of the factory equip as possible.
@ Josh- I wanna stay with Ni-MH to keep the $ down as well and to be honest don't know a whole lot (anything at all) about LiPos. What's their advantage?

@ Reno- Yeah I know I need to put some pics up. I have a bunch but I just signed up here recently and am doing this from my iPhone. Can't figure out how to load pics from that. I'll do it though. I have some group shots of my toys. :-)

I ran a 14v in mine for awhile, and it did well, its now a winter setup though. A friend stuffed a 18v in his emaxx. His gearing was about the same and so was the performance. So I say run the 18v if you got it. I abused my 14v with temps reaching 175 at times, no loss in performance over dozens of runs, so they can take some abuse too.

@Overdriven- Good info thanks. So you're saying I might not gain any performance with the 18V? Did his run the same temp as yours or did the more rugged motor operate cooler? And what about the speed controller temp with the 18? Is there a greater risk of frying that? What was the gearing and would you say it had more speed or acceleration than the stock setup?

[Overdriven]

Top speed on the 14v dewalt with the stock gearing was slower than the titans on stock gearing. So just swapping the motors will make your truck slower. I personally ran 21/65 which ended up noticeably faster than the stock setup with a bunch more torque too. On hot days I saw about 150 on the motor and 130's on the esc. I added a fan to the esc for safety and geared higher for awhile and abused the motor to the 175 I mentioned above.

My friends 18v needed a different spur and pinion combo because of the mounting of the motor in a Emaxx. But the overall gear ratio was very similar to my 21/65 combo, and temps were very similar to mine as well. So from what I saw theres not any real noticable difference in performance or temps between the 14v and the 18v in any way. So if you have a bunch of 18v, just use them, no need to go buy a 14v. But you will need to change the gearing to take advantage of the added torque and slower speed of the motor.

I still want to see what one of these motors will do on 6s lipo though, just for poop and giggles.

I never knew other voltage drill motors fit everyone on the Trax forum from what I know is using the same motor. 14v.

Personally I would probably get a kershaw brushed motor. I don't know enough about the drill motors to mess around with them.

from what i remember there is no difference between the 12v and 14v motors, but i could be wrong. Now i cant remember if i bought a 12 or 14v lol. As far as KD stuff goes i would stay away from it, i have never heard anything good about their stuff, but i have never owned any KD stuff either. But i figured since it was all word of mouth then it must be true.

What is the benefit of using a drill motor...when you have Castle motors out there? Heck, for that matter the Castle clones in Leopard Motors? What is deal here?
