    Question Motor tabs and DeWalt 14.4 questions...

    Hey guys, the positive motor wire tab on my Titan 775 just snapped clean off! It came off so clean you can't even see where the tab was. So, is there any way to fix it? I tried soder it back on, but there's nothing to soder it to so it didn't work. So, here's my next question, that I'm that sure has been asked a million times. How do I go Dewalt? Since I plan on going lipo I'd like to get the DeWalt 14.4 motor. What do I need to go Dewalt? I know a need to dremal the motor mount in order to make it fit, and I need to soder the wires on from my Titan, so is there any thing else? Also, where do I order it from? Any one got a link? Sorry if that's alot of qeustions, I want to make sure I know every thing before I order it. Thanks!

    Dremel the motor mount
    Dremel the pinion off from the DeWALT
    Solder 10 gauge wires onto the brush box of the DeWALT
    Solder a TRX connector on the ESC for the motor side
    Solder the motor wires onto a TRX connector
    Bolt everything up, plug it in, and enjoy!
    Whatever it is I just said... I could be wrong.

    Ok, more questions. Is going DeWalt worth it? I'm looking for a little more power, torque, and speed, so will the DeWalt give me "more"? Also, is there any cons to the DeWalt, besides a little less run time? Any other Pros/cons? Thanks!

    The dewalt has more torque.
    Pretty much demands to be over volted
    Is able to be geared up a bit more(re:speed) can take a bit more abuse and has replaceable brushes(which also makes it easier to clean the motor out)
    So yes it will give you a bit more
    It's not like the jump you see going to brushless but the truck will stay together much longer.

    One source that sells the DeWalt and better wires (10 gauge or 12 gauge high strand count) is RobotMarketplace.com.

    I'm sure there are others, too. You'll be better off with heavier wire than the 14 gauge on the Titan. Then you can use just two wires instead of four.

    One question I haven't heard answered is whether you need to add capacitors if you're using a 2.4GHz remote.
    What broke, uh, needs upgrading now?

    2.4 = no caps needed.

    Figure of speech ...the 775 does not enjoy being pushed beyond it limit ,not that it should.the dewalt can take more volts and abuse in general.almost prefers to be over volted called a14.4v but we run it on 16.8 v for the first bit of the run at least.has had 6s run on it.eats brushes pretty quick but continues to run after that much voltage.Its a tough motor.

    Ok, that makes sense. I read that you need to solder on the wires, and most people take them off of the Titan 775, but my Titan 775 isn't dead... So, where can I get some wires?

    Hobby shop or online there is a thread on here about that very thing.someone was also just asking.i would use single bigger wires from the motor.i combined my sets of output wires as I am not planning to run dual motors.

    EDIT. I just got Jimmie'd. LOL

    One question I haven't heard answered is whether you need to add capacitors if you're using a 2.4GHz remote.
    Two 14AWG wires have a cross-sectional area of 4.16 mm˛.
    One 12AWG wire has a cross-sectional area of 3.31 mm˛.
    One 11AWG wire has a cross-sectional area of 4.17 mm˛.
    One 10AWG wire has a cross-sectional area of 5.26 mm˛.

    Since 11AWg is almost impossible to find, unless you are going with 10AWG, you are actually giving up a bit by not using 14AWG wire.

    ProgressiveRC also has a good selection of wire.

    How much does skin effect matter relative to cross sectional area? If number of fine strands is important the Deans "wet noodle" wire (12 ga) would be good.... 1600+ fine strands vs ~600 fine strands in other 12 ga...

    I'll have to look at ProgressiveRC wire next time. Bought my charger there! ICharger 206B.

    Progressives wire description:
    "heavy-duty 10 gauge wire is made from over 1,000 strands of pure copper"

    EPBuddies description:
    "1050strands, 0.08mm tin-coated pure copper"

    Both are true RC wire which has a higher standard than any other wire I have worked with as far as strand count, flexibility standards, jacket temperature, and price. lol


    EDIT:
    Both of the selections above were for 10 gauge... I see that the description does not change for PRC on the 12 gauge for an apples to apples comparison but for the 12 gauge on EPB the count goes down to 680 strands.
    In either case, more than enough for what it is being used for.

    Ok, lets see if I got this right...

    Buy the Dewalt 14.4 motor from... ???
    Dremal the gear off, and put a flat spot in it.
    Soder new wires on... ???
    Dremal the motor mount.

    So, what kind of pinion do I need? Will the stock one work?
    Do the new wires come with the connectors on them?

    Thanks!

    I bought my DeWALT along with an extra set of brushes from ACE tool repair.
    Correct on Dremeling the gear off and the flat spot.
    Solder 10 gauge wires onto brushes. There is a spot on them to do this.
    Correct on the motor mount.
    Stock pinion will work.
    New wires do not come with connectors. I chose to switch the ESC over to a TRX connector for the motor over the stock bullets, so I soldered a TRX connector on the motor too.


    If you want, you can desolder the wires off from the 775 and use those.

    Here's a good example of how much torque the Dewalt 14.4 has and the amount of abuse it can take: I used my Dewalt powered Summit to tow another Summit for a good couple of kilometres, going over large rocks and hills.

    Pretty much no effect, but wet noodle is very nice wire anyway.

    Ok, thanks for the help so far guys. So, could I use the Traxxas high current connectors to connect the DeWalt to the esc? Also, if I used the Traxxas connectors, would I need one for the positive and negative wires, or do I just need one for the positive wire? Thanks!

    Yes, TRX connector to connect the motor to the ESC is possible. Only one connector is needed... both black on one tab, both red an the other tab.

    Ok, I found a place near me that sells them for only $27. Is this the correct motor? http://www.mendingshed.com/dwmotor396505-01.html

    If not, I'll get this. http://parts.sears.com/partsdirect/p...-21SV/0009/900

    And if all else fails, I'll get it from here. http://servicenet.dewalt.com/Parts/S...er=396505-21SV

    $27 before shipping... and they are out of stock. They were out of stock when I bought mine 4-5 months ago too.
    Shipping to me brings it to about $37.

    The last link makes the motor $42ish after shipping.

    Not sure on the second one... might be available for local pick-up?


    http://www.acetoolrepair.com/
    $27 before shipping.... $8.99 flat shipping and IN STOCK.
    Search 396505-21 for the motor and 603754-01 for the brush boxes. Motor comes with brushes... but might as well take advantage of their flat shipping costs.

    Just got my wire in from RobotMarketplace... the 12 gauge looks great. The 10 gauge looks MASSIVE... very thick insulation. Writing on each says:

    (12 ga) Deans Wet Noodle 12 Gauge Made in the USA
    (10 ga) JSC Wire & Cable Power Force Ground Wire #1660 10 AWG Proudly Made in USA



    Returned my 150w/220w solder gun to Radio Shack today. Planning to order this instead:

    Wolf, too bad I don't live in Salt Lake any more or I'd say let's work on this together! But I graduated from U of U in 2009 and landed in the middle of Kansas... 150 miles from the geographic center of the US. Nice folks here, but miss the mountains!

    Looks to be like a nice soldering set-up.
    Be careful soldering the 10 gauge pictured... it does not look like high temp jacketing.

    Those last links will work!, but I would go for 10 gauge on the motor instead of 12.
    Whatever it is I just said... I could be wrong.

    Think the temp rating should be fine on 10 gauge. RobotMarketplace gave this description:

    "When 12 gauge won't cut it, this is a nice, inexpensive 10 gauge wire, for current-hungry applications. This is a high strand count, with a flexible insulation, for a somewhat 'floppy' wire.

    Sold by the foot and by each color. If you want both colors, you need to add the first to your cart, then add the next color.

    Strand count: 413
    Diameter: 6mm
    High Temperature rating: 105C/221F"

    Would be nice to have 200C insulation but one web didn't find a definite temp rating for the deans wire either... One site listed it as 80C... But deans own site has no temp rating listed.

    Ok, so would this work? http://www.rcplanet.com/ProductDetai...=VIP6VSPLINE04

    This is me just thinking out loud, but if I use 10 gauge wire coming from the motor, but the esc wire is only 12 gauge, won't that cancel out the benefits of the 10 gauge?

    Also, what gauge is the wires coming out of the esc?

    Right, MR was actually set as the Geodetic base point for North American Datum of 1927. It is a bit closer to you.
