Hopefully you are only running it on 2S lipo? If it's overheating after 1 min I would gear it as far down as possible. 15/90 is as low as you can go I believe and although it won't give you the top end you may be looking for it will keep things as cool as possible. Also try running a heat sink and a fan on the ESC. Ensure your gear mesh is not too tight because that will fry things quick. And don't run the Sidewinder ESC on 3S with the 5700 motor.
In my SLash I run a Sidewinder ESC with a Velineon (3500kv) motor on 2S and turn my end point on my radio down to 85% throttle. After a single 6 minute qual race I am running around 135-150 and am running 18/86 gearing.
Hope that helps.

Glad it helped.
That should be a good combo to run and should give you a lot more run time. I personally think the only Castle motor suitable for 1/10 trucks is the 4600kv because of heat issues but also because it's able to run on 3S lipo with the Sidewinder and is insanely fast.
Are you running a 2.4Ghz radio by chance? You can also adjust the end points to keep your motor from being overworked.
The guy that told you about gearing it too low can overheat should find a new profession.
A smaller pinion turning a bigger spur gear means the motor has a lot less force being required to turn the spur. Think of it like a bicycle. The pinion is the little sprocket your feet are turning and the spur is the sprocket in the rear that your back tire uses.
When the chain of your bike is on the very smallest sprocket on the rear it's incredibly difficult to peddle but once you are able to the top speed is great. Quite the opposite when it's on the largest sprocket. Easy to peddle and lots of torque for climbing hills but zero top end. Which would be easier to do on a flat surface? That's how your motor "sees" gearing also.

I just put the 5700 in my sc10 and had to turn down the epa to 55% to make the truck drivable. It's FAAAAAASSSSSST

I would seriously consider selling just the 5700 motor and buying a Velineon motor. DON'T buy their ESC as the Sidewinder is far superior but their motors are pretty smooth, can be geared to be very fast and on a track w/2S will be plenty fast enough to keep up and win.
I just TQ'd and won my last couple races with my Slash in Open SC and raced against 2 SC10's and 2 other SLashes. Also running the 17mm wheel conversion which is a MUST to beat the better handling SC10 trucks.

That's why I had mentioned I think the 5700 is not the best choice for it. If you have to turn the EPA down to 55% just to drive it you are probably running too much motor.

ran my slash this afternoon with a 16/90 gearing and after 5min i temped at 140 on motor and 120 on esc i am running a computer fan on my esc and so far its working greathow did you get that integy heatsink fan work on the slash, i tried mine and it did not fit
