    1/10 esc with 1/18 motors?

    is it possible to hookup a 1/10 ESC to a 1/18 motor? if not, why not?
    From what I can see 1/18 ESC's doesn't have thermal shut-down, and looks to generate a lot more heat then there bigger 1/10 brothers.
    Isn't the technology the same, only on a smaller scale?

    really? so it is possible? what car are you using it in? what setup do you have?

    The only thing with using a 1/10 esc Is make shure you have extra brushes..I have a mc230cr on my mini-t and it is sick fast!! But about every 8 runs on a 7.4 lipo im changing the brushes..

    hi scooter1985, cool another person to run this setup. I'm actually looking at brushless setups

    You shouldn't have any problem running a 1/10 esc with 1/18 motors. The only time you would have to worry is if you ran it the other way around.

    I found a deal on a Tekin R1 for the same price as the MMP/Quark. It actually has a smaller footprint than the Quark

    Brushless Is the way to go!! Maintence free! and super fast! Also longer run times..I think towerhobbies now has the new mamba system for $100.00 u.s. I know for fact that if you run 1/10 esc on 1/18 motors it sends extreme power to them,and runs very fast but eats brushes like crazy!

    RE: 1/10 esc with 1/18 motors?

    wow that's awesome, I might try a vxl esc with my xcelorin 9200kV 1/18 motor... if it's possible, why do people even use 1/18 esc's? the price is about the same, but with less features... the weight can't be that much different to justify it

    A 1/10 esc just handles more amps and it's bigger and heavier - that's the only drawback. it wont GIVE more amps, it HANDLES more amps.
    you MAY find smoother utilization on very powerful motors that may be limited by a small esc, but expect that from larger/faster/more loaded motors.

    RE: 1/10 esc with 1/18 motors?

    Quark roadster here
    When I was pushing a 666w monster (Jae introduced me to trying new motors really. His list of comparisons racing multiple motors on the detta was inspiring), 3 A123 2300mAh cells and a 3200kv 28mmx56mm can...
    http://beomagi.ath.cx/pics/rc18t/bigbl/P1000275.JPG

    Still I do feel safer using this than using my mamba or even quark when I'm pushing higher voltages on larger/faster motors.

    I'm definitely going to be investing in a sidewinder system. It's not the amperage of the mamba max, but it's nearing that league with the ability to push 540 can motors up to the 5700kv mamba.

    NOTE - If amps and how much a speed controller can handle seems like dark magic :
    amps increase with voltage - so 2 lipos being the limit on a mamba 8000kv motor means that's the amps it should take.
    amps increase with the decrease in motor resistance. less winds = more kv = less resistance = more amps.
    amps increase with larger can motors - a large motor like the ammo 5100kv 28mm draws much more than the 5400 mamba.
    amps increase with cogging! If you're cogging you're wasting FAR more power than you may realize, as the motor jiggles itself around.
    amps increase with load - a heavy chassis, binding of drivetrain, getting stuck in mud/rock and forcing yourself out (beware rock climbers!), constantly accelerating and braking, wheels too large, gear too high. If you motor works harder, there's a lot more current than free rolling.

    Even if you're running a motor IN spec, and you're cogging, forcing your wheels free when stuck, or stopping and starting roughly, you can damage the esc. Even if you're motor is out of spec, but you're driving well, smooth drivetrain, smart choice in gearing, you should be ok!

    Thats probably in part because the mc230cr is not using as high a frequency as a full competition esc. Lower frequency esc give more torque and are cheaper; but they are not as smooth, make the motor get hotter, and wear the brushes out faster.

    Well I have a car that will only fit mini batteries...will a 1600 mah battery on a bigger esc for a mini-t still make more power?

    I think beomagi explained it already, but a 1/10 esc is able to handle more power before giving out. It won't give you more power.

    Not true...A 1/10 esc WILL give more power to the motor...I have several hi end 1/18 esc..and they are no comparison to even a cheap 1/10 esc

    I'm pretty sure that might better firmware or better build quality. Having better quality fets will have less resistance. The motor is going to demand the same amount of current on the same gearing no matter what esc you use, its just a matter of will the esc take it. If thats what you mean by more power then, I guess so.

    However, most high quality brushless ESCs(mamba, quark, Losi, tekin) have enough current handling capabilities for 180-280 motors when you go by their recommended gearing. They could easily bring up max current handling capabilities by stacking fets in parallel, but for practical and normal use, the 25-35 amps continuous current handling is good enough

    I've tried a mamba and a quark and I couldn't tell any difference in power. I'm moving to a Tekin 1/10 R1 esc, and I doubt I'll feel any noticeable difference. Its just with the gearing and drag brake I have set for high speed runs, I don't want my esc to let the smoke out like my Quark did

    RE: 1/10 esc with 1/18 motors?

    from the responses it looks like people have tried this setup. But now the interesting thing is why do people choose 1/18 esc's over the 1/10? why compromise so many features? The only reason i can come up with is that the 1/10 esc can't fit in their mini's. I'm sure a little modding can fix this...?

    Does anyone have any pictures of their 1/10 esc with 1/18 motor setup?

    Yea, I guess it was size at first, as well as price. I think most 1/10 and bigger competition ESCs use to be over $150.

    Thats all changed now. You can pick up a 1/10 sidewinder for $70 shipped, thats cheaper than the MMP. I just looked on tower, and the MMP and 1/10 sidewinder are the same price! Its kind of on the big side, but you can still fit it in most 1/18 cars. If you can get a smaller rx, a 1/10 esc should be able to fit with the extra space the smaller rx provides.

    So like you said, theres not really any reason not to pick up the bigger scale ESCs now. Tthere seems to be a lot of bigger scale escs that are meant for people who want to go brushless for cheap, but aren't in competitive racing, so they don't need the high dollar setups.

    I think once sales start slowing down and more people start realizing this, Castle will be forced to reduce the price of the MMP to the price of what the 1/18 sidewinder is currently selling. That will then force other 1/18 escs to come down in price to stay competitive. It actually almost looks like that right now as 1/18 sidewinders are hard to find.

    Anyways, in a couple years, their won't be a need for 1/18 escs as 1/10 and 1/8 ESCs will probably be the only thing manufacturer's need to sell.

    I was about to pick up one of those Quark roadster ESCs. One just ended for $60 shipped last night. Car looks good! By the way, what chassis is that?

    Custom rc18r chassis cut from 1/8" high impact polyethelyne. Modded steering to go with a sorta upsidedown xray steering setup.

    Running with my baja body.
    http://beomagi.ath.cx/pics/rc18r/baja%20red/ (large pics warning)

    That motor is the ammo 5100 28mm. Running the baja and rc18r leaves a
    lot of room for 1/10 esc's. unfortunately, quark is now in my m16tc, so i'm looking at a couple sidewinders.

    Just got my 1/10 Tekin R1 esc, which has the same foot print has 1/18 mamba ESCs


    You can also see my hi-tech water cooling motor heatsink :P I just calibrated the radio to it and will try and get runs in tomorrow

    You know guys,I got to thinking..1/10 esc's are big,but you have to take the good with the bad..2-wheel drive cars flip very easy..Mount it up front so it ads weight!! Also when this thread first started we were talking about brushed esc's the got on the topic of brushless..
