2S means 2 Cells, 3S means 3 Cells and so forth.

2S lipo for cars usually equates to a voltage of 7.4V which is the max voltage the ezrun ESC fan will take without modifications. 3S is 11.1V which is too high for the stock ESC fan to take which will either just burn or blowup if you attempt to do so.

For the ezrun ESC to run a 3S, you'll have to change the fan to one rated for 12V DC, that or rewire the fan leads to the BEC port on your reciever.

I for one would never run without the fan. I dont see any advantage by not using it but I can see a potential problem, no more esc.

No

I would not recommend any of the Ezy Run motors in a slash.

I would suggest an Ezy-Run 60A speedy and a Traxxas VXL motor

I have this combo in a Tamiya DF-03RA and on a 3s Lipo we cracked 60mph!

The ESC does get very warm if the fan stops spinning (had my plastic fan guard get caught up with a fan blade)

From what I can see on the wiring though, it looks like it draws power from the Servo wire end, ie the BEC. In that case, shouldn't the stock fan be sufficient even on 3s Lipo?

Ok, here goes:
35A, good for up to 1/12 on-road
40A, good for 1/12 offroad
60, OK for 1/10 offroad
80A, good for 1/10 offroad
120a+, good for 1/10 offroad, ok-good for 1/8 offroad

...or, spen your money at thetoyz.com and buy a VXL system for $140 new. Yes, you read that right, and check out the website... Or, snag a Mamba Max and worry about other things (like how much crashing at that speed will cost you )

Everyone seems to be making most of their comments about what EZrun fits what car. People who ACTUALLY have them seem to say or in some cases, show, that the 35A 13T runs well in 1/10 cars like a Traxxas Rustler. I hate to keep pubbing this guy's thread, but it's a good one to show the capability of the 35A, 13t:

http://www.rcgroups.com/forums/showt...ighlight=ezrun

I bought one and have only been able to run it in my basement (too much snow outside) but I can tell you that just spinning donuts in the basement, the esc and the motor stay pretty cool, while a similar 15t brushed motor was too hot to touch.

No, it's not as fast as a Mamba, Sidewinder or Velineon, but it is a good replacement for a stock brushed motor for about the same price.

You don't even own one. Also you can get a 5.5 for under 100 and I much prefer the EzRun compared to my mates VXL.......Why don't you buy one from there? as I see you are wanting to buy one

The Hobbywing + VXL is a great combo, for any rc car over 1600 grams I'd advise going a VXL or similar motor as opposed to the Ezy-Run (and Mamba Max) motors which have a smaller rotor. RPM and speed is one thing, but with more weight comes the need for more torque. You could also look at the Feigao motors here.


My DF-03RA weighs in at 1700 grams (300 grams less than my Slash did) I have it geared pretty hard (FDR is 7.1) and even on a 3s Lipo, I have never had the motor top 140 degrees farenheight. When I tried a 13t Ezy-run motor in this and in a slash, I struggled to keep it under 170!

Same ESC, different motor, makes a difference.

I was talking about the esc as i know the smaller HW motor have probs with heavier cars....

Has any one tried their 540 sized motors?
