Ok. Go with 12v or 14v Dewalt on Summit? I have 14v I am going to wire up this weekend. But can pickup a 12v at the Dewalt Service Center tomorrow.
The preferred motor is the 14.4V version.

Very cool. Seems like a lot of work!
Bash OR crawl? No, the Summit does it all!
I really want to do this but just replaced my blown out 775 with another 775.... BOOOO!!!!!!!
I purchased a few. Robinson Racing pinions and spur gears to experiment.
GusinCA... its actually not alot of work. Its not a "quick" job by any means but its not really that hard. You just need to hit a few key points and your good. IMO... if your not unhappy with how your titan is running, this upgrade is NOT worth it. Its better but not THAT much better than the titan. If you want more power though, this is the way to go IMO>
Right now it's a cheaper motor upgrade me than a Tekin rx8.
finished installing my Dewalt tonight, used an axle C clip from a RWD Ford 8.8 rear diff (0.125" thick) for a spacer, did not have to notch it since it fits perfectly against the ft of the motor, it required a good sharp drill bit tho to drill the holes for the screws. I'll try it out this week end and see how it goes.

This is the most thorough post on dewalt conversions on the web. This guy really knows the motor inside and out. He helped me out when I was gearing my truck. After trials for awhile on the motor he found that the 21t is a good mixture of speed and regular temps. The wonderful thing about a Dewalt is it can be overvolted and overheated to an extent without damage. These things are Bulletprof and make the titans seem like they are made of glass. $5 worth of brushes every 2-4 months is about all of the maintenance they need. Go here and ask any questions you may have, there is a good chance he will know the answer if he hasn't posted it in the thread already.
Stupid question: How did the DeWalt affect the run time?
This is a signature.
With the stock nimh batts it will kill them pretty quick. I wouldn't install a dewalt without running lipo as well

Mountains cant stop me
they have tried
It certainly draws more amps... thats pretty clear from the power it produces.
Its power hungry if its geared very high. Geared for about the speed of stock though 13/68 its about
the same amp draw.
Its been cold so iv been playing with gearing. Currently have 20/65 and it still runs. Approching 4s brushed speed. Its also covered in snow though... would thermal very quickly if it was above freezing.
I have been running a Dewalt 14.4 with 68/14 and was impressed. The other day I picked up a Dewalt 12v, soldered on some leads and set it up with 68/20... Running 4s. First thing I did was launch SpeedBox app on my iPhone and taped it to the body. My top speed went from 21 mph to 30 mph. The acceleration was insane.(at least when compared to the before.
I was able to pull wheelies on the road at about 50% speed...flip the truck on it's roof fwd and reverse from a dead stop. I drove up to a curb and punched it. That resulted in a double summersault, landing on my wheels.
Bashed a ran at top speed intermittently for about half an hour. Didn't break any parts.
Crawled: a little touchy..but doable in low gear.
Temps: motor was too hot to hold my hand on for mor than 3 seconds. Esc heat sink was kinda hot too.
Batteries: temp=cool. 2 x 2s 20-30c 5000mah Tunigy lipos ($19 each) per pack voltage after run ~= 7.54
More experimenting is needed I currently have the following gears to experiment with:
Spurs: 68,65,62, and 58
Pinions: 14, 16, 18, and 20
The Dewalt's are truly the poor man's brushless
This is one of the cleanest dewalt install i have seen pave, very helpful.
hey did you or do you recommend breaking in this motor as you would a 775?
I didnt break in the dewalt motor really at all. I propped up the truck with the wheels off the ground and let it run at 1/4 throttle or so for about 10 minutes. That was it.
I figured, who breaks in their dewalt drill? No one. You just buy it and start drilling holes and they last forever.
great write up
is there anywhere you can buy the dewalt motor already set up with wires and brushes installed? so you dont have to deal with soldering, etc
how do you turn the 4 plug into two bullets?
pavmentsurfer used 5.5mm Castle Creations bullet connectors, reds together and blacks together. I used four 4mm bullets but then came around to pav's point of view.

Got this finished on new year. Excellent and detailed write up
Going to use it as a back up motor when the stock 775 gives up
You can see some surface rust forming on the can...that's from leaving it in my car for 4weeks with the Canada snow

Mine is really rusty on the outside. At first I wasnt liking it. But after a while it kindof grew on me. Looks kind of junk yard ish.
I just got my motor in it looks like I received 398505-00. When I ordered 396505-21. What motor did I get? this motor is big 1 7/8 in diameter and 2 5/8 long
this is the only thing I can find and its an 18v
