atomic stock r evolution motor review

hi folks...

did a search, but zip... anybody got this motor? mine just came in today... been itching to try it out and write a review...

but one thing is bugging me... although the website says that the basic requirement is 3010, do you think it's safe for 3004 fets?

thanks for any replies... (man i'd really hate to be a guinea pig in this situation)

from the atomic website...
Basic Requirement: MOSFET 3010 x 2 / (1 layer)
Turns: 44T
Endbell: Type M1
Body:
1.) Neo Magnet
2.) Dual Ball bearing with High efficiency cooling case

Performance (on 4.8V platform):
RPM (Non-Loading): 34000
Current: 1 AMP

Recommend Gear Ratio”
MR-01,015,02: 5.38:1 to 4.30:1
AWD: 6.38:1 to 4.97:1

from the above thread i saw some pics... looks like an older stock 3004 fet chassis... but not certain...

- the motor didn't come with any capacitors, and in some of the pictures that were posted, i saw some capacitors soldered onto the motor... is this necessary? (to reduce motor noise i'm guessing) or can you just use it as is without the capacitors? (sorry if my noobie side is begging to show)

Herman,

I don't have mine with me right now, but IIRC, it is just like the Chilli motor(but Chilli will requires more fet upgrade)--there are three SMD caps soldered onto the endball, somewhere between the two comms.

Herman. Christian Tabush posted (if I remember correctly) that this motor pushed the limits of the 3010 FETs. I wouldnt run it with 3004s.

How do you know the above car doesnt have stacked FETs?

FWIW, Im running mine in a stock Firelap with no problems. That dang thing is still slow, but I think thats a PCB problem. When installed in an AWD it is real fast. Id say its close to the speed of my 4562 2x2 AWD with Xspeed V. Its a very good motor, and the fastest Ive run on stock FETs, but Im leary to try it in my 02 or 015 (both have 3004s).

I thought they all came with micro caps? They look like a little green board between the tabs. I run mine fine with those on 3010s. I wouldn't even try them on 3004s either...

I used to run one on my awd, but have recently switched back to the atomic awd I was running before as the fets were getting real hot and I didn't notice that much of a difference with the awd stock on my carpet. I did have to switch out my usual pinion as I ruined the thread, but I don't think the plastic pinions slip that much when overheated?

The stock r tore up my rear alloys on my 02 though lol so be careful!

thanks for all your replies...

you're right... atomic came out with two variants...
the chilli evolution - which requires a fet upgrade of 2x2 4562 fets....
and the the stock r evolution - which is supposed to be for stock fets, but looking at the atomic site, i found out that its supposed to be 3010 fets

was kind of curious if anybody tried the stock r with the older stock 3004 fets...

unfortunately my motor didn't come with any capacitors soldered onto it, but it did come with a micro cap? (if that's what they call it) as pfc pointed out...
it is a very small little green board between the tabs...

warning another newbie question coming up... so if this is indeed a micro cap, would it mean that i won't be needing anymore capacitors on the motor?

so i guess... at the moment, the safest assumption is to just use the thing on a fetted car...

i will take pics of the motor soon and post shortly... thanks again to everybody...

yikes!!! what alloys were you using? what tires were you using? and where were you running it?

just took some pics earlier...

180 hk$ approx 23 us$


out of the packaging...


close up of the micro cap?


does this mean capacitors not required? thanks for any reply...

Those three small ceramic capacitors on the pcb should take the place of the leaded ones we are all used to seeing between the motor wires and motor can. There should be no need to add additional caps.

kja812 is right, you should'nt need to add additional capacitors to the motor.. They've been using these style of capacitor's on 1/10th scale brushed motor's for the last couple of years... It's nice to finally see this type of capacitor mounting on 130 class motors...

Good motor, especially when running single layer 4562 fets.

i really like my stock r as far as smoothness goes. i run one with a Spinner ESC in my Sinister and it gets pretty sweet run times with plenty of punch.


but comm oil quickly stripped my motor can sticker

It puts out lots of torque. You can feel it from the strong magnets compared to stock Kyosho. It also decelerates very strong due to these magnets. From the Atomic charts it can be seen that the stock R evo is more powerfull than a chilli over the complete speed range, but I do not know how accurate and comparable the Atomics measurements are.

I use the Stock R Evo on my AWD with stock Fets. The only thing is that the two pins with the wires attached stick out underneath the chassis and the thin wires are exposed as well. I suppose an alu or alloy motor clip will touch the pins and cause a short circuit.

Just put thin layer of tape between the motor and mount.
