    Motor runs hot

    The motor gets to about 190í, I have a 2wd Rustler that needs a new esc so Iím looking to get a new esc motor combo for the 4x4. Been looking at hobbywing, looking for suggestions.

    Hobbywing makes good escs. For motor, you could go with Castle, or even Gear Shop. I like my Gear Shop motor. Tons of torque and speed. If you want a specific esc from Hobbywing, the EzRun 60a esc works pretty well.

    After testing the 4x4 at my lhs I think this truck is a perfect candidate for the castle 2400kv! Paired with a mamba x, or your esc of choice, the motor would really wake up the truck. Seriously, this truck needs, no deserves, more motor.

    Personally I ripped the hobbywing stuff out of my trucks. Had their esc in two of them, not anymore. You won't regret castle.

    Did you have problems with them, or just wanted more esc?

    I had problems with the lvc on one and the fans on both. I couldn't keep a fan actually working on either of them. I had always gone with castle Esc's prior, decided to switch it up. They were the ezrun max8 if it makes any difference. Tmbold, that would be the one! That motor is longer than the stock one, and while it looked as though it would fit, a quick double check might be in order.

    That's personal preference, I prefer the 5mm but if you don't have 5mm pinion gears you'll have to buy them. Bigger is better though, right? Remember, gear that motor up!

    what kind of gear change would a person do with the lower kv.

    You'll want to gear up. Bigger pinion, or smaller spur.

    When I had that system in my slash 4x4 (and my 2wd slash) I used 3s for normal use. Once geared up, 3s is plenty. Every once in awhile I would throw 4s in them, just to break something or those inevitable "hold me back" moments. Instead of buying a dedicated 4s pack (which likely won't fit) think about a series adapter and two 2s batteries.

    Whoops, sorry about that ksb. I guess I should have said the inevitable "watch this" moments. Tmbold, you and me both brother! It's a deep rabbit hole and easy to get lost in it, ha!

    The vxl system is fine on 2s, the problem is it says 3s on the box! While the system will run it, it was never designed to bash on 3s. In the lighter 2wd vehicles you can get away with 3s, not on these heavier 4x4s.

    That is my very favorite motor system! Some call it the sensored El Sob special motor system. I know that will love it in your Rustler♡ I have had the sensored version in one of my trucks since it was first released. It still runs as beautiful today as the first day it was installed. 3s is good power and speed. 4s is a whole lot more fun! 6s ( even though the motor isn't rated for it but it doesn't over rev it ) is absolutely crazy! Looking forward to seeing your truck in action

    I hope you like your new system. I'm curious to hear how you like the Mamba X with the 2400kv 1415 motor. I might have gone with a Sidewinder 8th system instead. The Sidewinder 8th combo is cheaper, gives you a bigger motor (1515B 2200kv), and an ESC that can handle just as much if not more power (Sidewinder 8th). The only thing the Sidewinder 8th system doesn't do is Sensored mode.

    The "problem" with the Mamba X ESC is the same "problem" that the Mamba Max Pro had. It was designed with significant size and weight constraints in mind (at the expense of extra heat), due to all of the people using them in lightweight racing buggies and similar. If you're just bashing, then you don't really need an ESC that was designed with such a focus on being small and lightweight, and overkill with a heavier 8th scale ESC is usually a good thing. My Mamba Max Pro had similar specs to the Mamba X and I was hitting thermal shutdown with that more often than I would have liked while paired with my older unsensored 2400k 1415, before I broke the shaft (3.17mm) on that motor. That was in a heavier Slash 4x4, and I hope your results are better.

    Just remember to take temps often on the first run! While that motor is a bad mamma jamma, I don't think it's ever been run in a 4x4 rusty. While the gearing I gave worked fine in a 4x4 slash, and should be fine in your rusty, at this point it's all speculation. I'm excited to see what it can do! Make sure to report back, possibly a running video?

    I thinking about getting the hobbywing Ezrun 120 esc and 3660 3200kv motor. Anyone have experience with this system?
    My esc hit thermal the other day when I was running the 17 tooth pinion. Just doing speed runs on the road. That was with the traxxas fan on the esc and a fan on the motor

    If you have enough space, that's good.

    What I end up doing in my slash 4x4 was an aluminum plate, and recessed screws so it's all flat and use the whole area to stick my ESC as I have virtually no space constraints.

    That motor system look at home there! It has plenty of space. I personally always use a heatsink with fans on all of my trucks. You should be very happy with it

    So I take it you like? I bet that thing was beastly on an 18 tooth pinion, can't imagine 20! Keep us posted, and maybe a running video?
