just wondering what kinda speeds u think u are getting with the 2826/8?

im thinking about trying them out on my emaxx. cause at work i get the kms ones but the same rating for cheap.

Here is my current setup plugged into Brian's speed calculator. It seems like it's alot faster I think. But maybe it's because it accelerates very hard and tops out quickly.

It is a really fun setup. :yes:

Differential Ratio: 2.8461538461538462
Transmission Ratio: 1.84
Other Ratio: 1
Spur Tooth Count: 40
Pinion Tooth Count: 22
Total Voltage: 14.8
Motor KV: 1130
Tire Diameter (inches): 5.75
Tire Ballooning (inches): 0
Motor Current Draw: 0
Motor coil Ω: 0
Spur/Pinion Ratio: 1.82 : 1
Total Ratio: 9.52168 : 1
Tire Circumference (inches): 18.06 inches (458.83 mm)
Total Motor Speed: 16724 RPM
Vehicle Speed: 30.05 mph (48.26 km/h)
Effective Speed Rate: 2.03 mph/V (3.26 kmh/V)
Estimated Adjusted Speed: 29 mph (46 km/h) - 4% loss
Effective KV Value: 1130

As you can see from the pictures earlier in this thread, it is a rather small motor. At only 36mm x 54mm, it's putting out some power.

AXI quality is hard to beat IMO. They use some of the strongest Neo Magnets around.

If you use a cheaper outrunner, it may not perform so well.

The AXI first appealed to me because of the optional cooling fan to help control motor temps.

I tried this on 5S and it just screams, but it was on the verge of overheating the motor even with the fan.

I think I found one of the KMS motors in this size: http://www.hobbypeople.net/gallery/108512.asp

Are there other turns available? I also wonder if the AXI fan would fit this?

yah those are the motors but i well be using a 2826/04. i get them for like 40$ and if they ever go out i can just defect it out lol and get my money back or get another one haha. (good thing about working at a hobby shop and your boss is really cool)

Heres the 04 motor like the 06you linked to. 1000kv!

Half the price of the axi. wonder if it is any good. You gonna buy one sike?

Hey that is a pretty good deal! :yes:

Can you get me a good price on one too? I wouldn't be looking for a warranty or anything. LOL

Got any pictures of the butt end of the rotating can of this motor?

Yeah, lets see the butt end!

Man I need help!

yah i can get you that deal. just u got to pay for shipping. i well get some pics for you tomorrow.

I might! hehehhe

Something that makes me wonder here, in comparing the turn count to the AXI, these are ratings are just about the same for half the turns. I wonder if this KMS motor is a Wye wind?

THAT would make it even better IMO. It would be especially nice if the fan will fit. Does it have the 3 screw holes in the endbell?

1090kv! :yes: Every little bit counts. LOL

I would like to get one, install it and compare.

Excellant Dr Kros. I appreciate that. Not a problem on the shipping.

I can get some side by side comparison with the AXI this way. :yes:

yah i think it does have the 3 screw holes in the endbell

I took the E maxx out for a run again today on 4S. 4S is perfect for this. Motor temps are in range, ESC is cool, Lipos are cool.

A couple of guys at work are getting into the hobby. I plan to run them with this setup.

One guy just bought a new T maxx 2.5 and the other is picking up one of the new E maxx's tomorrow.

I'm not gonna show them how this one runs until they get their's out. LOL

It's gonna wax their butt. :rofl:

Just a thought, how about a pair of them, since they are using the same spur you may be able to wire them to the same esc. Griffinru did it and I have a pair of aveox motors that i wanted to wire to the same esc, but could not figure out how to time them the same. Someone recently posted to hook up a battery to two of the leads on each motor and they would be timed the same.

That's very possible. I might try that. It would work with much higher gearing then for more top speed. Use the 25 tooth pinions with a 36 tooth Revo spur. :yes: Hmmmmmmm..............

Dr Kros, I want the 4 turn.

In comparing the internal resistence values:

AXI 2826/8 is 30 mohm's

The KMS 2826/4 turn is listed as 64 mohm's.

If I were to speculate, my guess is the KMS is a Wye wind. This might make it even better than the AXI. I wonder what kind of magnets it uses?

Another thought here is, I bet the AXI endbells would fit the KMS stator assembly perfectly.

You sure about that resistance? This page lists it as 32!

http://www.hobbypeople.net/gallery/108510.asp

The KMS resistence value at that website must be wrong, another site I found lists it as being 32 mohm's.

The AXI 2826/8 shows 2.8 amps no load at 10v

The KMS shows 3.2 amps no load at 10v.

Something isn't right about these figures.

Greater amp draw usually means higher kv and lower resistence.
