RE: ezrun brushless
ORIGINAL: bhcvc
Lower kV usually requires more voltage, so you usually can't use the exact same setup. Ideally, you want the motor to have a no-load rpm of 30-40k (keeping in the 30-35k range reduces current consumption). Depending on the load, you can run lower rpms than that and still run efficiently. Whether the 8.5T (4000kV) or 13.5T (3300kV) will pull less current on the same battery setup is a guess. The 13.5T will be spinning much slower on 2s and while that usually means less current, there is a point where lower rpms will require more current to move the same load. Now if you ran the 13.5T on 3s, that will be very fast and powerful and still be in a very good efficiency operating range for the motor. If I had to guess, I'd probably say the 13.5T would run cooler on 2s if you're not gearing it for insane speeds. Or, since you run 2x 2s packs already, you can run them in series with a 17.5T motor and get yet more torque and you'll probably be able to run the big tires you have and not worry. I ran the 17.5T motor on 4s in an E-Savage without problems and the E-Sav is bigger than the Himoto.

maybe you should of tried online 1st before going to hong kong as they seem to be all over the place, tip for anyone looking
if you google and cant find them in stock and your set to english try another language and country

RE: ezrun brushless
Hello,
Is the XeRun brushless just an updated version of the EzRun? Does anyone think Ican get away with competing with a Novak brushless, or similar? Everyone seems to be using a namebrand 10.5 of some sort atmyhighly competitivelocal track.Iplan on using this setup in either my T4 or B4 on 6-cell NiMh. Any suggestions? Can Iget away with the EzRun 10T, or should the XeRun 10.5 be my obvious choice?
Thanks!

RE: ezrun brushless
The EZRun is sensorless, and the XERun is the "premium" sensored model.
The whole number motors (9T, 10T, etc.) that the EZRun uses are smaller motors. These are fine for lighter cars and people just wanting an upgrade from brushed, but they will not likely compete with "name brand" motors in off-road competition.
The ".5" motors (10.5, 8.5, etc.) are the same size motors as the industry standard and will perform much better.
Many racers prefer sensored operation for the ultra smooth starts and braking, but both EZRun and XERun ESCs will perform great.

RE: ezrun brushless
Awesome, thanks for your response!
One more question:Just out of curiosity,howabout using the EzRun 60A ESC with a XeRun10.5 motor? I understand that the ESC is for sensorless and the motor is sensored...but does anyone see any issues if I am using it to race in my B4 w/6-cell NiMh?
Thanks.

RE: ezrun brushless
on ebay i saw a thick black thing sticking out of the ESC is that a capacitor or something? it's not on my 35amp esc and i was wondering where i could stash it on my slash (when i get the money to go brushless there)

RE: ezrun brushless
I'm thinking of getting a 35Amp EZ-run ESC to use in my Brama 10b (modified the buggy)
What would be a good voltage for a motor. I was thinking 4700kv one but I'm not sure seeing I've never tried brushless.
I'm shooting for somewhere in the 8.5 or 10.5 turn range
Does anyone have any recommendations, and is the 35A ESC too little for what I plan?
And for now I plan on using a 5000mah NiMh pack I got to power it. I might upgrade to 2s lipo later on once I get some extra money.
any input or suggestions would be greatly appreciated.

RE: ezrun brushless
I ordered mine from here
http://www.hobbypartz.com/brushless-...bo-system.html
I went with the 60a ESC just incase the 35 was to small. Just did not want to chance it.

RE: ezrun brushless
What esc and motor combo would be good for a stampede XL-5. I will be using a 8 cell high quailty NIMH. thanks in advance, i just dont want heat issues

RE: ezrun brushless
35amp is only usable with the "whole integer" number motors (which are 380motors in 540 cans) the 60amp ones can be used with the half integer 540 motors... I love my 9t/35amp ezrun system which works great on my 6sNIMH pack but i havent tried that offroad... youtube has some vids of slashes using them so i guess they do work on the bigger/heavier cars...

RE: ezrun brushless
Hey guys I need a motor similiar to a 10.5 brushless motor, it's 4200kv. What would be the closest from ezrun a 10t or 9t? I think the 9t because it's 4300kv.. HELP ASAP!

just remember guys these systems dont compare to higher dollar systems, don't except the same amount of quality or speed,

RE: ezrun brushless
I think Hobbywing should stop selling the whole number motors as 540-size as they're not. That's deceiving and many people won't get the performance or reliability they're expecting from those. The finned whole number motors and smooth ".5" motors cost about the same and in any application where the finned motor is planned, the smooth motor will run better. So for anyone asking about the finned (whole number) motors, I'd recommend looking at the smooth (".5T") motors instead and whatever equivalent/similar kv rating you need.
As for the HW systems and their performance relative to "high-end" systems...the HW makes BL systems for many brands. All of Speed Passion's sensored stuff, as well as Orion's sensorless and Venom's sensorless stuff are rebadged Hobbywing EZRuns or XeRuns. And the HW's use the same FETs as the "high-end" brands. Discounting them because of their country of origin is silly and ignorant. Keep in mind that not many of these US brands make their own stuff. They *may* design them (often times not either...that's usually contracted too), but virtually all electronic items now-a-days are made overseas, often times by the same brands that end up coming out on their own to offer their own brand. Not taking anything way from the other brands, but don't discount the HW setups. The ONLY thing they lack is domestic customer service, which for many is a deal breaker. If that is your reason why they are "inferior", that's valid in terms of the overall package of product you're purchasing, but not for the electronics themselves.

RE: ezrun brushless
that's a bs call, not to start a war here, But there motors have 380 sized arms, compared to 540 sized arms in mamba motors and the vxl and neu's and such, (not saying the vxl is just as good as a neu) when it comes down to raw power, the ezrun isn't the way to go.

RE: ezrun brushless
Yes, HW makes both 380-sized and 540-sized (internals) motors. Their finned whole-number motors use 380-size internals, which is why I say they should stop marketing them as 540 motors. Their smooth-can .5T motors are true 540-size motors. Unfortunately, I think this thread as an equal ratio of misinformation as it does true information.

RE: ezrun brushless
i have a ezrun 60A with a 5.5t ezrun, in my tamiya TT-01. i just switched to 3S lipos and am having quite a bit of "phantom" full throttle at slightly long distance, meaning i will be pulling the throttle roughly 10%, but it will go full throttle in a quick burst and turn hard right.... i tested it with the regular nimh batteries i was running before and no problem, settings perhaps? any ideas?
thanks for your help.
