Cons
Hard on transmission and diff gears
Almost impossible to get a 540 can motor in a mini
Huge weight problem that means excessive heat and batt discharge curve
I use 1/10th ESCs in all my 1/18th but use mini motors as designed for the vehicles
whats the pros/cons to having a 1/10 esc/motor in a 1/18
PROS =
Starship Enterprise-like warp speed capabilities.
Learn how to use a dremel.
CONS =
Free membership to your lhs's Frequent Buyer's Club (because of increased crash damage).
Increased tire wear.
Having to explain why your car is slower despite having a larger motor than your buddy's (from doubling the weight of your car) and living with the humiliation.
Having local track operator ask you to submit urine sample for drug testing.
Increased drinking while spending time thinking "WTF was I thinking?"
Pros:
Better Throttle feel.
More Torque. Depends on motor.
Access to faster Motors.
Higher Voltage set up.
More reliable ESC.
Electronics can handle more throttle abuse.
Cons:
Weight Can be negated with Lipo set up.
Space, very little space to play with so you have to playe around.
Diffs and gears need to upgraded, it will be hard on the car.
Heat the bigger motors tend to get hotter.
Well I don't know about 1/18th but heres my 1/16th with a mamba max.. I know its kinda cheating because its just a 10th scale touring car just made 80mm shorter, and not a proper 1/18th scale car.. but you can't have everything...
To be honest with 3s lipo in my experience you can get more than enough speed out of a mini scale brushless sytem, and it will be a lot less work and a lot more reliable and better handling than a 540...
And if you mount the motor facing the same way I have (longitudinally along the chassis) then expect insane torque steer as the whole car leans over to one side when you accelerate.... This is so bad that my rear tires wear unevenly
I'm using a mamba max 5700 and a 3cell a123 battery and I can't use more than 3/4 throttle, it will just flip over...
But for me it was more about building it that playing with it... So if you like experimenting and building and testing... then it can be great. Just don't be surprised when your result is an uncontrollable part (and wallet) destroying monster.
Sorry guy's not to high jack the thread, but since were talking about installing a 1/10th scale ESC in a mini. My question is can a 1/10th scale vehicle be equipt with say a Mambe mini max pro ESC and a normal 1/10th scale brushless motor? It would be nice to just buy a 1/10th scale brushless motor for my XX4 & be able to share the ESC between my RC18t & the XX4??
i was thinking about a 1/10th esc and a 370 or 400 motor both brushed would this decrase runtime or performace or would this be in the best intrest of the car

I would imagine the bigger, heavier car would melt the wires right off your electronics or maybe even melt your speedo if you were to try it. There's a reason the 1/10 scales use the fat wire, because they pull and eat alot of juice (electric).
Deonte - I just put a lrp quantum 2 and the stock 370 motor in my rc18t. The esc fits excellent, works flawless, and has a little better brakes. The stock esc in from the 18t rtr though is no slouch. I honestly don't think there is much difference between the two performance wise besides the rtr having reverse. But there would be no motor limit on the quantum 2, but also no reverse.
Wouldn't you gain more punch with a good 10th scale esc ?
There was a post of 2 M18 in the M18 thread Packed with 10th scale electronics ! CRAZY LOOKING !
If you was to use 10th scale elctronics, would you still be allowed in official Races ?
I'll start by saying I'm no electronic engineer or anything, just an avid rc racer learned by trial & error.
You may get a little better punch by upgrading the esc, but most likely that would be due to upgrading to a better grade unit than would come with the car stock. The motor is only going to pull so many amps, and as long as you're not exceeding the stock esc's ratings they should remain pretty close. Now you may gain some runtime though if the esc is more efficient and better able to provide the needed power, and running cooler while doing so. And ususally whith an upgraded esc you will get more choices in how you set it up, so you could gain more punch by having different profiles you can change on the upgraded esc compared to a stock which generally all you can do is set the throttle/brake and neutral settings.
I couldn't tell you about racing and legal problems with minis, I'm new to the mini scene myself. But I don't see where it would be a problem unless you were running a stock or spec class. But you'd be best advised to ask the place you plan on racing about what you can and can not do to the car and remain legal.
i am using 12T brushless with 25A ESC for my 1/18 micro, with 14T pinion & 38T spur gear, the problem is my motor comes very very hot by only 2 minutes of running, any body knows to solve it..
My first 1/18th came with a motor but no ESC. I used 3 different 1/10th ESCs just to test them in the car. Compared with 3 other identical setups with 1/18th ESCs, I was a noticeable amount faster out of the corners, and I had more runtime. Getting 18 min with the stock stuff, 22 min with the 1/10th. I know with mass production some motors may be faster and more efficient than others, but they guys I ran with insisted they thought it was the ESC, and I can say theirs got warm, mine never got 5*F over ambient temp. I didnt run stock for long, so I never got to do a control test with another motor.
