Which one is better for the E-maxx cause the Dewalt motor is a little cheaper thean the Titan 775 motor. Bye the way I'm talking about the 14.4v Dewalt motor, I would be doing maily bashing with the E-maxx but a little bit of crawling as well so I need as much torques as possible. I would probaly run the E-maxx a 14.4v but might just do the regular parrale series wiring. The main thing that I need is speed and torque.
 
I'm running the 14.4 in my summit more torque and speed I'm running 16t pinion 68 spur.much better motor, bearings instead of bushings easily overvoltable,Replacable brushes. The new style requires very little modding to make it fit I'm very happy with it runtime is a bit shorter not much running 2x 2s 5000 30c lipo I'm never goin back to the titan 775:)

I need to know which one you are exactly talking about, beacuse there are several different dewalt 14.4v motors on ebay so if you could please post a link to it on ebay that would be appreciated. "thumbsup" So I need just 1 or 2 more peoplew to chime in and tell me there thpoughts not that i don't trust you but i wanna make sure I do it right the first time with my E-maxx.

I couldn't agree more with everything said, dewalt motors are the way to go. I so happy I put a 14.4v dewalt in my summit over the stock 775.
 
Pawn shops have cordless drills for 5 bucks most of the time I bought a 14.4 and 18 volt Drill. the 14.4 was a 550 series motor and the 18V was the 775 motor. After ALOT of searchin the spec for 14 V was 27 turns limited to16 volts and I burnt it up after 4 11.1 v battery runs in a 2.5 revo that I built a motor mount from scratch to crawl with and it was walking speed at best. The 18 V was also 27 turns and can handle 36 volts max. I ran it on the same rig 11.1 lipo and it had the power to pull a steeper gear ratio so I got about 20-25 mph.
TWO BADS for 18V 1 it had A pinion pressed on that I could not change but it was .8 mod so I used Jato spurs to gear it. 2 while I was charging the lipos my charger caught fire and burnt it and my accord into a pile of scrap dammit.


Sorry so long but there's alot that needed written
 
I am debating now about actually just sticking with the cheap 18v circular saw motor. It has a lot of torque, I think the 14v would be faster though.
 
To get the most out the 18v motor it needs 18 volts or more. Which isn't possible with the EVX2 you'll need a different esc that can handle that much voltage. You're right the 14.4v has a higher kv rating so it will be faster. I'd suggest getting the 14.4v.
 
Thanks for the info, It will be faster, will it have more torque, or at least as much? Thats the thing I don't want to loose, I have other rigs to go fast, and this one rarely sees high range, so I don't worry too much about the speed.
 
Torque is not an issue. I ran a 12volt (the lowest torque of all three popular dewalts) and it was simply crazy with power. Enough torque to pull a small house. I once ran it on 5s lipos (just for testing and speed runs) and was getting in the mid 30mph range with high gearing, I think is was 22/54 - but she was hotter than hell. Then one day I forgot I had it geared so high, took it out to show off to my friends and burnt the internal wires. It was smoking like mad but still running. Lesson learned - don't show off - heat is definately your enemy - tall grass add to the stress of over gearing. With that said it was a 12volt, the 14.4 volt runs cooler and I heard it was faster still.

If you already have the 18vol then run it. You can gear it high (much less heat) and still hit 20mph on 2s lipo. I would suggest 20/58 or higher for good results.
