    Budget Brushless

    Budget Brushless


    Ok so these days of poor economic activities is taking its toll on your hobby.
    Getting tired of babying you titans or modding to fit drill motors that only provide a minor performance increase? Well I want to help you go Brushless without breaking the bank. Donít worry about battery upgrades as the combos I am about to list are nimh friendly,
    Now onto the escís.
    Ok this is the most expensive part of going Brushless. For the best 4s esc ( mamba max ) its 130$ and I strongly recommend it . the only part about it is that from the factory it will only run 3s. so we have to mod it to run 4s. I will show you step by step
    Heres the basic look of the setup with a rx pack.

    This step is mandatory! you need to take out the red wire from the esc rx lead. And heat shrink it and tuck it away. Like so.


    once you have this step done you can relax and plug the esc lead into the receiver and plug the rx pack or ubec into the receiver

    that is the basic of getting a esc to work on 4s
    ok here is a list of cheaper solutions for escís that are tested to work.

    Easy run 60 amp 3s esc, it runs about 60$ from *********. The only addition to the mod from the mamba is that the fan cannot take full voltage of 12cells or 4s . you need to remove the fan wires and splice them into the empty rx ch. 3 like so



    Here is the link to the esc http://www.*********.com/*********/s...verse_programm.

    Now if you donít think you can handle the mod then this is the esc for you.
    It does not require the mod and it has a bec built in so no nasty ubec or rx packs.

    http://www.rc-monster.com/proddetail...rod=HW80ampesc


    its more like a mamba monster but remember its only 12 cells or 4s and its quite large .

    now its motor time.
    Now heres the touchy thing about cheap motors,
    They like to run hot! I mean Hot. Hot. Hot.
    But they do give really good out put. Its very smooth. You just have to gear correctly and watch those temps . 160 Ė 180 being normal but any thing above 180 is too hot. You will need to add one of these



    so I really suggest getting a temp gun like this

    http://www3.towerhobbies.com/cgi-bin...&I=LXEMG5&P=ML

    itís a really cool toy that has many more uses than r/c . I use mine to cook bbq and check the a/c in my house.
    Ok back to the motors.
    The cheapest you can buy is a hobby king 9xl and itís the most prone to over heating too. Quality is a trade off on a 30$ motor, so you will have to gear around 20/68 to keep it cool and you will need a heatsink http://www.rc-monster.com/proddetail.php?prod=RCM01
    You will need size XL to fit the 9xl . this also keeps the endbells clamped onto the motor.
    Ok heres the link
    http://www.*********.com/*********/s...hless_Inrunner

    Again this motor is a heat machine you have to watch your temps!

    Ok now onto another motor ,

    This one has a little more quality but is still a hot runner.

    http://www.bidproduct.com/part/Produ...MOTOR_184.html
    get the 1850kv for 9xl but I suggest a 1660kv for cooler running and nimh.

    Now here are the best bang for the buck and they are talked about a lot. And I race a 12xl
    They are feigaos. They are very nice motors and are very smooth. They will run hot if not geared correctly but they run cool on nimh so I would not be worried. They run about 70$ so they are not all that cheap. But they last a good while and are great motors for starting out in Brushless. The windings go like this.
    7xl fast powerful but hot! Lipo only*
    8xl good mix of speed and power but runs very warm. Lipo only*
    9xl this is a power monster is not as fast as the 8xl but its more fun I think. It also runs warm but not as warm as the 8xl.
    10xl best mix of bashing and cool temps comparable to a dewalt 800 12volt on 16.8
    itís a good easy on batterys motor.
    http://www.rc-monster.com/proddetail...WAND_XL&cat=20




    Ok if you want a long lasting motor fast and powerful than I suggest you look at medusa
    They are very good they are 4 pole motors and run cool they will also last the longest and will be a worry free motor when driving. The ones that work in the e-revo are the 60 and 70mm models the 70 being best
    Link http://www.medusaproducts.com/motors/036-V2.htm
    Model numbers that work
    MR-036-060-2000V2-5 lipo only!*
    MR-036-060-1800V2-5
    MR-036-060-1600V2-5
    And the 70mms
    MR-3670-2000V2SE-5 lipo only!*
    MR-3670-1600V2SE-5

    The models with the * are only to be used along with lipo batterys for the best performance.

    That wraps up the list of budget motors. Now batterys

    Batteries.

    Im going to suggest you run lipos with any Brushless setup but some motor combos can use nimh fine.
    But it goes like this

    do not use nicad , venom or any other off brand pack. You must use gp, ib , eng-c , or ep cells or your batterys run the risk of venting .
    you can get nice batterys from
    http://www.specpointbatteries.com
    and
    www.promatchracing.com

    ok on the wrap up you need 5mm pinion gears to run these motors as they all use 5mm shafts they can be got here http://www.rc-monster.com/proddetail...nion5mm&cat=40

    any of these setups will out power any brushed setup you can fit in this truck
    running any one of these combos is like running dual dewalt 800 12volts.
    Donít believe me? Here

    Unless you own a MM esc your are better off buying the MMM, as the cost of a new MM + BEC or batteries is more than picking up a new MMM off ebay or many resellers.. you can get a MMM for about 140 now w/o any problem on ebay. MMM combo's are 250ish which means you don't save much doing anything, and the only motors close to the performance of a Neu (any varient) are the MedUSA motors and they cost as much as a Castle Neu or Flux tork on ebay Sorry just had to throw that out there..

    I agree that you're better off buying the MMM. The Castle Neu is an outstanding value for money when purchased in the MMM combo. I wish everyone the best of luck with their Feigao clones, but mine grenaded in just a few runs and I had basically no recourse.
    MMM/2200 powered E-Revo - sufficiently excessive

    I have no Idea how many runs on my 36-74 6XL, even many High Speed Runs on 6s, and it rocks!

    More than enough power on 3s, and does back flips on 4s..

    I think what rc 12 was trying to say was that your really going to make some tradeoffs between price and duarbilty and the MMM for alittle more money will save you in the end.
    If you dont like it, just change the warranty.

    Hmmm, my total cost was $168

    I run a MMMv3 and a 36-74 6XL (2800kv)
    MMMv3 was $140
    36-74 6XL was $28
    Total $168

    And It Ripps!

    Lets see, trade off would be I saved 100 bucks!
    Issues I've had, Hmmm nothing but fun..
    Highest motor temp after a 15 min bash was 160*

    IMO if all your talking about is cheap , this is a hard combo to beat, http://cgi.ebay.com/EZRUN-80A-SD-367...1%7C240%3A1318 But also there's rebuilt Novak motors, which are of a much higher quality then the Fiegao http://www.shopatron.com/product/par...21.26355.0.0.0 I much prefered my 4.5 to my 8xl. Get that and a 75 dollar Ezrun and you should be good to go 45 all day long, yet gear conservatively and make nihms happy.

    Don't you need a sensored esc to use the Novak 4.5 ?

    No you can run it sensorless. But the Ezrun will run as sensored also.

    Is that a ********* motor or a Feiago motor?
    Pair that up with the EZrun 80A thats $75 bucks plus $28 for the motor and we have a $103 dollar winner!!!

    Killer!
    But that esc will only go 4s vs my 6s MMMv3
    and I'm not sure it will take the amp draw the 6xl will pull?

    Yup, it'll run it just fine. I bought the EZrun 80 as a backup for my MMMv3 and run it with the castle 2200 monster motor on 4S with no problems It's a very good esc, especially for the low price.
    Where did you get the 36-74 6X? Is it a Feiago or not?

    Cool, Thanks brushlessman. I found it on the website.
    I guess I can order it and try it out with the EZRUN 80AMP and see if this nice $100 setup will work
    If it does, I may package it and sell it on ebay LOL

    On 4s I get about 43-45mph..
    and again on 6s with 5000mah 12c bats, I managed 58.1 mph.
    I bet I could get more if I used higher amp batteries..
    all this on 20/68 gearing

    I mostly run 2 3cell in parallel, plenty fast on the track (nuts actually), and does not over work my batteries..

    Ok guys, snapped a few shots of the EZrun 80 compared to the monster.
    It's got plenty of size and has handled 4S lipos with no problems. It's huge! I really think this ESC paired with the motor filmmaker has posted will be the best low priced combo you could get. It also mounts directly to the stock holes in the chassis with no mods needed.

    I have a few questions about radios with these escs. Brushlessman did you use the stock radio or did you have to use a 2.4 radio? and with the ezrun do you have to use 2.4ghz?
    Are you an RC addict?

    Oh. I always thought you HAD to have 2.4 to run most bl systems. Thank you so much! 2.4 was one of the main things that was stopping me from going bl because of the cost.

    It really all depends on where you mount your Rx and how you wire up your antenna/tube...but 2.4Ghz is WELL worth the money, and is an upgrade everyone should invest in.

    I just ordered the ezrun 80A esc from rc-monster, along with a faigao 9xl motor. I am not expecting crazy fast, but it should be a big step up from the T-maxx I am converting.

    May I ask why a battery like This one will not work for this setup?

    I am definately going to stick with nimh, as I am not ready to go to lipo, but why do you recommend the SPC's or Pro-match? Will the above DuraTrax work?

    Thanks for the help.

    You will need two of those packs run in series, but I am not sure of the quality of Duratrax cells...I have heard they are not very good. You really need a good pair of 7-cell packs.

    But why pay $38 a piece for crappy NiMH packs when you can pay $39 a piece for excellent LiPo packs?

    The motor you are using needs lots of amps to run good..
    You need a battery that can give 70 to 100 amps cont and 140amps+ bust.

    The battey you listed is only rated to maybe 35 amps and will heat up bad due to the motor pulling more amps than that battery can put out leading to battery failure! ahhh

    I know this is a budget brushless thread, but the 150a ezrun combo does everything the mmm does and includes a fan on the motor, which allows higher gearing on a given motor. I never thought a fan would make such a dif. until I did some testing on my brushed e-savage. I was able to run a 22 tooth pinion on the same setup with a fan that only allowed an 18 at the same temp(160degrees). Not sure it would be directly the same, but a few teeth on 6s would make a huge difference.http://cgi.ebay.com/Ezrun-1-8-Truggy...3A1%7C294%3A50

    hahaha no the mmm is way better , them motor is better. it does not need a fan. it is just a better system.
    but yeah that duratrax pack should do,

    If your definitely gonna stay with NiMh, I would use these over the ones that you linked to:
    http://www.spcracing.com/index.php?productID=14

    I'm not sure how they would perform either. They may hold up if you take it easy and watch the temps, dont know for sure.
    Lipo is really the best choice though
    $28 bucks a piece for these and that combo will HAUL!!!
