    What motor an esc do I need

    I have a fiesta brushed I want to make it brushless but I don't want to use the traxxas Vxl system I want a castle Creations motor an esc combo that would fit with little to no modification. Does anyone know of one that would work

    These are intended for 1/18th scale but will work with the Fiesta but you will need the motor mount from a VXL. You could go to one of these but you will need to make sure you have some good batteries to handle the power that that system can pull. That will make it a totally new beast to drive!

    Fist off, the Micro pro is not intended for any of the 1/16 scale and there are tons of topics here that can back it up. I wouldn't get anything less than the SV2 in the Castle line up.

    How much trouble would it be to modify it for the sv2

    Please...

    DO NOT use a 1/18 system in your 1/16th...

    IT WILL FAIL.
    Whatever it is I just said... I could be wrong.

    You can use a bigger system in a smaller truck, but not a smaller system in a bigger truck.

    I have no intent of using something that wont work in my fiesta. that's why I posted on here. I just want to find a nice alternative esc to the traxxas vxl system because i've heard how easy it is to over heat the esc. I want something with power just don't want to cut up my frame to make it fit

    Are you 100% stuck on Castle?

    BTW:
    Those that have cut it was by choice, not necessity.

    There is a decent set that will give you stock 380 brushless power available on a site that we cannot mention.

    I must not be too tough on my mini stuff, never cooked an 1/18th Castle system or over-heated my VXL ESC

    Honestly, for what you can find a mini Velineon motor for on eBay that's the motor I'd go for. On 2s the power is very manageable and usable, 3s is nuts but with some finesse it works great, and 4s is psychotic. Pair that up with the SV2 or Mamba Max Pro and you should be good to go. If you do this you will need a new motor mount as the brushed motor is a bigger motor. If you run one of the motors from the SV2 combo they will bolt right up but they're tougher on batteries and will raise your CoG. The SV2 motors will not run as hot as the mini Velineon though, it's up to you.

    EDIT: I have the STRC aluminum motor mount and a heatsink on my motor with some thermal compound just for good measure and my ESC and motor both make it through ~40 minutes of indoor racing just fine in a Mini Revo which is heavier and more demanding on the motor than a Fiesta. Indoor temps get up around 90 even this time of year and very humid from wetting down the track. Just my personal input, I'm 100% content with the factory motor--you can pair it with whatever ESC you want as long as it can handle ~50 amps continuous without a problem.

    The Sv2 can be bought somewhere in the neighborhood of $70 online and is made to handle 1/10th scale RCs, it should have no issue handling your Fiesta.

    I'm not familiar with the brushed motor mount on the Fiesta so I'm not the best qualified to tell you which one to run, but if it works the way it does in my head then a regular 380 mount (such as the stock one, STRC one like I've got, or any other brand) should slide onto the mounting pin then screw right in. If that's the case I may have my stock mount around here somewhere, you could have it.

    EDIT: Found my stock VXL one:

    If it helps, you can have it. It's cheap cast aluminum so it doesn't soak up as much heat as a milled piece but hey, it's free

    28/45 is stock gearing for use with your 6 cell NiMHs or 2s lipo (I think). I keep my MERV at stock gearing on 2s and I'm pleased with the balance of speed, heat, and run time it gives. You can tinker with it from there however you like. Definitely get 2s as soon as you can, you won't believe the difference!


    This is my setup, haven't seen the temps hit over 160 even after long runs

    Can't hurt, IMO the stock setup is pretty good. There's a bunch of them on eBay for pretty cheap. I've been looking around trying to find good gear ratios for you but there doesn't seem to be much to go by so far (or I just really need to go to bed, either way). Stock ESC will get a bit hot, especially thrashing it on 3s, but if you don't have any binding in your drivetrain and your mesh isn't too tight IMO it works fine. A fan will definitely keep you in the running though. How do you usually drive it?

    Here is what you will need to convert to a 380 motor from your 550:
    7077 Gear cover/Hardware
    7090 Motor Plate
    7060 Motor Mount

    Yeah and because I'm also doing the transmitter too it's cheaper to get a vxl 1/16

    Yeah, the LINK probably pushed it over the edge... lol.

    You'll have fun with both, I'm sure.
