im currently awaiting delivery of whitie's lancer evo and wanted to pick up a nice motor.

im currently trying to decide between the atomic t2 or the evo chili motor

according to mongo the stock fets can handle 7 amps

Mongo wrote:

The EVO's can handle up to 7 amps. Tested at 9 amps but I would not push them that far.

Those values depend on how hot the FET's get. The hotter they get, the less amps it will take to fry them.

im leaning towards the new evo chili motor but im wondering if its safe for me to run it on a stock ep?

according to AM's these are the stats for each of the motors:

Atomic T2

* RPM @ 4.8V = 34,734 (1.5 Amp Draw)
* RPM @ 6V = 43,600 (1.8Amp Draw)
* RPM @ 8.4V = 59,240 (2.6 Amp Draw)

Atomic Chili Evolution Motor

* RPM @ 4.8V = 43,000(1.4 Amp Draw)
* RPM @ 6V = 50,000 (2.3 Amp Draw)
* RPM @ 8.4V = 63,300 (3.3 Amp Draw)

the evo already has a JDR li-ion setup, gpm rear diff & rear cvd's already installed
so im not sure on which motor i should pick up?

what kind of stack you got?
im planning getting a 3x2 stack on my evo that already has li-ions

let me know how it works out :D

I just received my Atomic Chili Evolution motor + upgraded FETS today. I'll tell you how it works out after I get it installed.

so true

i still cant decide on which motor i want to use
i use my xmods for mostly drag
i would do track racing but i got no one else to run against

im currently running a custom fatboy made by my friend a few years ago
i dusted it off and dropped it into evo and it totally smokes my first gen 8O

too bad i warped my comm for my favorite 40t handwound motor :evil:

anyways im thinking about grabbing the chili for use in my 4.8v setup and t2 in my lith setup for a safer setup with my stock fets on both evo's until i get some 2x2/2x3 fet stacks then ill switch the chili once i do get fets

does this sounds good?

according to AM's stats
no other motor hits as high a rpm at 4.8v like the chili

Atomic Chili Evolution Motor

* RPM @ 4.8V = 43,000(1.4 Amp Draw)
* RPM @ 6V = 50,000 (2.3 Amp Draw)

Atomic T2

* RPM @ 4.8V = 34,734 (1.5 Amp Draw)
* RPM @ 6V = 43,600 (1.8Amp Draw)

anyone have a estimate of what the chili's rpm/amp draw at 7.4v?

also looking at the t2's stats compared to the chili it seems it would be pulling less amps under load than the chili would under load

Could have been many things.

--Radio interference for a short while because of a radio, microwave, whatever the case may be.
--Your board was a little to damp and needed to dry. There might have been a slight short because of the water, and that went away when the water dried.

Sometimes things like this are just unexplainable. ;)

Re: atomic t2 or atomic chili evolution motor on stock fets?

this mornin when i decided to play with my car for a minute outside while it was still wet and tried to do some light drifting

i was gettin to much traction while trying to drift but after a minute i decided to stop because the high risk of me frying my board

When i got inside i took out the batteries and tried to tap out the excess water.

After that i slapped them in my first gen to do a lil speed run in the narrow straightaway in my room.

i then tried my batteries in my evo for an comparison and found out that it wouldnt receive any signal from my remote. :?

At first i thought it was the remote and the crystal but tried different crystals and remote with no success.

i took off the board cover to try and dryoff any excess moisture and still no success :evil:

well i decided to leave the board open while i went to sleep and woke up to find out that it worked fine again. 8O

im very happy i didnt fry it but i want to know what happened to my car?

didnt he say the stock fets limit for an evo is at around 11.1 amps?
if i remember correctly

I saw an older post from Mongo...let me grab what he said...
Oh yeah! It's the link in my signature...
[quote:0df709aa2e="Mongo"]EVO's can safely handle 7 amps. They will blow at 9 amps continuous current.

If I were you...and would rather pay another $10 because you're getting it from AM instead of RCMart...I would just buy one of Teammnm's motors.

Yes, Ph2t is the designer and (was) the manufacture of the Nelly external FET boards. ;)

He may have said that, but that does not necessarily mean that you board will withstand that amount of Amp draw, just because his did. He may have done extra things to his board for it to have done that, I don't really remember.

Would a T2 be a wiser choice? In my opinion, no. The T2 would not be as efficient as a Chili, in my opinion mind you. Get which you believe would suit you better. ;)

Have you thought of where you plasn on running this car? I ask because it sounds like you're looking for all out speed...not very practical with an xmods range.

Otherwise, you should really consider a fet stack...in a comparison test a while back ph2t ran a Plasmatomic(similar amp draw) on a stock evo and it didn't take very long for the fets to pop. :wink:

Re: atomic t2 or atomic chili evolution motor on stock fets?

i wanted to pick up a motor to run on the stock fets since i wont be upgrading my evo's fets until later on but when i do upgrade the fets to 2x2 or 2x3

i wanna hit up freestylexmod for a fet installation on my evo's when i have time

i did notice it was fashioned after the larger 1/10 scale motors thats why i want it out so much

i really want to try out the chili evo motor because of their improvements over the t2 with the new gen style motor but i dont think the fets would last long so i might just grab a t2 for safer usage

teammnm's IDR racer plus armature sounds promising also

Teammnm IDR Plus Armature

* 26 turn hand wound short armature
* Enamel wire dia. (.30)mm
* Silver Commutator

* Produces better performance at a cooler temperature
* Best used with 4/6 cell NiMh set up, May be used with lithium-ion setup

Volts Amps RPM
4.7 .99 43110
6.0 1.01 46050
7.2 1.09 52240

IDR (In Door Racer) Tall Gear Ratio Two Cell Lithium-Ion Setup 42mph (67.5kph)*
IDR (In Door Racer)

Tall Gear Ratio
Two Cell Lithium-Polymer Setup 47mph (75.6kph)*

*Actual ground speed may differ from speed test on the speed checker

what yall think bout this one?

Also, go with Chili. You'll probably notice a greater improvement with the Chili, than you would the T2 because of the different end bell configuration. (M1 style. Used in larger scales. Incase anyone didn't know. ;))

You are totally correct they are on no loadl, imposible a motor like that sucks that little current, Id also go with the chili because wath donzi said, and a FET upgrade, because this:

[quote:f618253da4="Atomic Mods"]# Requires:Minimum is 2x2 FET stack, although a 2x3 is recommended. If you are using lithium, go for a V2.

Re: atomic t2 or atomic chili evolution motor on stock fets?

It's safe as long as you stack the FETs. I would go for the 3X2 orto be on the safe side for either of them, but at least a 2X2. If you want to run the Chili...your gonna need a heck of alot of room.
